NMEA Data Sharing Across Applications and Platforms

Posted on Fri 23 September 2011 in Coastal Explorer

Systems - Electronics Slug: nmea-data-sharing-across-applications-and-platforms Status: published

With a Maretron USB100 NMEA-0183 Gateway and an Actisense NGT-1 NMEA 2000 gateway I was struggling to get the NMEA data to all the applications on my PC, iPAD and iPhone. Many applications can not only connect to the an NMEA data source but also share the data on another TP Port or Virtual Com Port. Originally I was using a complicated stack of software all connected to each other to get data to some of the applications but couldn’t really use them all at once. More importantly which ever app I felt like using at the time might require starting up two applications!

Well in comes GPSGate Client (\$40) which lets you connect to a data source and then share it with many other applications.

You can see in the graphic below that I’ve dedicated the Actisense Gateway to Coastal Explorer. GPSGate is then connected to the Maretron Gateway and then it is used to serve up the data to 7 other applications some on Windows and some on my WiFi iPad and iPhone.

Also of note is that my preferred iOS navigation application Navionics works fine on the iPhone since it has a built-in GPS, but on the WiFi iPad there’s no way to get the NMEA data into the application. I’ve contacted Navionics about this and we’ll see if they add the functionality.

NMEA Data Sharing

This is greatly simplified from the way I was doing it before and I’m very excited to not only have all this finally working but to have it working simply! \$40 for GPSGate was worth every penny!


Setbacks and Problems

Posted on Mon 05 April 2010 in Projects

Systems - Hull Slug: setbacks-and-problems Status: published

This week was full of unexpected issues and problems and very little movement forward on projects.

It started out when we noticed the some leaking with our newly installed portlights, which is fine really, a bit of tweaking was expected. However the leak got into the new wood (which was not marine grade) and caused it to swell. So we’re going to have pull down the new cabin top wood and re-seat the portlights to do that. We are not looking forward to that as the new wood was put up with epoxy, much grinding or demolition is going to be involved in that. New marine grade plywood has been ordered, if you learn one thing from me do not skimp on materials. I don’t normally skimp we did this one time and it bit us hard. Take the time to do it right and use the right materials.

This next one really pisses me off. When I had the yard install the conduit in the mast I also specified that they pull messenger lines to the masthead, spreaders and foredecksteaming light. Well they did that but they didn’t make the holes big enough for the wire. I didn’t specify a size and they didn’t ask so this is really a communication problem (one of many with the yard) but I’m not sure why they would drill any holes without explicitly knowing what size. So, I had to drill new holes in the conduit and snake new messenger lines. Once that was done I find out that I still can’t get the wire to pull through because at the angle I’m pulling (90 degrees right out the hole) all I can do is flex the tubing once the wire has exited. I can’t get any more vertical pull. That lead to an almost complete meltdown on my part. I was thinking I’d had to eat the cost the boat cable and pull primary wires instead. Now I’m thinking maybe I can pull back several feet of the insulation and still pull the wire. We’ll see. I’m sure it’s going to be another week of dinking around with that whereas I expected to be done pulling wires this weekend.

Dawn did make progress on some painting though. When we originally pulled down the hull lining and painted we left all the teak in place that covered the chainplates. We have since removed that teak and pulled the chainplates to clean them up and we’ve decided we’re going to not re-install that teak instead leaving the chainplates uncovered so we can see them and any leaking or corrosion issues. So Dawn has been painting that exposed fiberglass white to match the areas we had previously painted white. This is good because now I can start rebedding the chainplates. I’ll have an entire post on that process.

I didn’t really want to write this post, but I figured it was important so you can all learn from our mistakes and see that doing a refit like this is a lot of work and despite planning things will go awry. So with that unpleasantness behind us we are ready to kick much but in the next couple of weeks with our complete focus on everything needed to re-step the masts.


More Wiring

Systems - Rigging Slug: more-wiring Status: published

I've been updating the drawing so it's more detailed than the original version. I'm getting to the point of needing to determine the number and size of things like terminal blocks, ring terminals, heat shrink tubing, etc.. Along with this I'm also getting ready to dry fit everything to the spars down at the yard before the final prep and then painting of the spars. I'm spending a lot of money having these things painted and I'd rather bounce the drill off the unpainted sand blasted spars than the newly painted spars.

And We Fell Off the Proverbial Horse!

This post was written by Dawn, edited by Patrick

Everyone has heard it before…if you have ever purchased something that moves fast or could potentially be dangerous. You always receive the standard advice from just about everyone, “Just be prepared when [insert bad thing] happens, because it’s not a matter of if it will happen but when it will happen.  I’ve heard the warning as kid, while I worked at a horse farm where I rode and cared for horses. “It’s not a matter of if you fall off, it’s more when you fall off.” And I did, multiple times, and yes, I always got up, dusted myself off and got back on that proverbial horse.  And I also heard it after purchasing my first motorcycle at the age of 21 and yes, I dropped my motorcycle, a couple times, and yes, I got back on.  And, both Patrick and I have heard it since purchasing Deep Playa, “It’s not a matter of if you’ll run aground, it’s when you’ll run aground.”  And so here is our story of running aground in Deep Playa for the first time.

After we peeled off the raft up at the Lats N’ Atts party in Poulsbo a few of us continued our wonderful sailing trip and headed north towards the San Juan Islands for another week. Our first stop was in Mystery Bay State Park, according to the website, is a “10-acre marine park is reachable by car or boat. The park features 685 feet of saltwater shoreline on Mystery Bay and offers a spectacular view of the Olympic Mountains.”  It sounded wonderful and peaceful especially after the debauchery of the weekend. Since we were the first boat to leave Poulsbo we arrived at the mouth of Mystery Bay a few hours prior to the other boats in our raft up.  The entrance to the bay winds through a narrow and shallow channel and then opens up to the bay.  We decided to motor all the way down to the bottom of the bay and drop anchor and wait for the others to arrive.  Absolutely no problems! After having some very “mysterious” things happen to the other boats, such as batteries not charging and transmissions getting stuck in reverse. We confirmed that our fuel tank gauge wasn’t functioning either.  Luckily, before we ran out! We decided to wake up early and head over to Port Townsend, WA to fill up the fuel tank and to top off our water tanks.  After pulling up the anchor we headed out of the bay and thought it would be a great idea to leave on an ebb in hopes that as the tides shifted to a flood that it would push us quickly over the Straits of Juan de Fuca.

Something that we learned early on after purchasing Deep Playa was there are a few poor design decisions made by the previous owners. One of which, is the depth gauge is mounted on an interior bulk head.  The helmsman must bend over and remove his/her sunglasses and look 6 feet through the companion way to read the digital display.

We were feeling comfortable (maybe too much) about our perfect navigation of the channel the previous evening, so I hopped down below and started making some food and getting ready for our trip.  Bad idea! All of a sudden I felt a jerk.  I knew that wasn’t right and by the time I ran over to the companionway to see what happened, we had hit a sandbar and we were stuck!  YIKES!  After a few choice words, we both hopped into action, mentally and physically preparing ourselves and the boat for whatever may come.  We hailed our friends to attempt to pull us off of the sandbar but they weren’t powerful enough and they too were concerned about running aground.  So we hailed Vessel Assist and they were there in 20 minutes!  The captain showed up and told us that he needed another boat because his wasn’t powerful enough.  So we waited for another boat.  As we waited, the wind started to pick up (blowing us into the sandbar of course) and the rain started.  Perfect!!!! Patrick and I felt uncomfortable of the heeling that was increasing due to the tide moving further and further out but the captain from Vessel Assist assured us that that was nothin’!  We felt a little better due to his presence and his reassurance.  He told us that we should check the sea strainer since we were running the engine in shallow water.  We did, and it had some seaweed in it but it wasn’t too bad.  While we waited he said that the plan was to have the second boat tie to the main halyard while he pulled us off using a bridal off the bow cleats.  The heel from the second boat would lift the keel free and he would pull us into deeper water.

Twenty minutes later the second boat showed up and they prepped to pull us off.  Our biggest concern was potentially damaging the mast head and the bow pulpit.  As things got underway we just sat back and held on for the ride.  As she was being pulled off and we were heeling over to the point that the lifelines and portlights were in the water I began to get nervous and in response to that anxiety, I began to chant, “She’s a good boat…she’s a good boat…she’s a good boat.”  Patrick looked over at me and said “What the heck are you saying?”  I responded, “I know she’s a good boat! So why not chant it!”  Our new tagline for Deep Playa: “She’s a good boat!” After several attempts she finally popped out of the mud and we were once again in deep water!

After this, we sprang into action, checking all of the systems and starting the engine before the Vessel Assist guys left us.  I ran down below and opened up the door to the head and whoosh!  Water flowing down the hull and onto the floor!  I ran over to the bilge and checked, not too much water, we’re OK!  I ran back into the head and tore everything from the storage areas to investigate the leak.  The clamp fitting for the hose connecting the sea cock and the drain from on deck was spewing water everywhere.  It had become over loaded by the copious amounts of water coming from above deck.  (Just add that to the list to fix) Luckily we didn’t take on too much water and things settled down very quickly.  However, I did lose a hair dryer to the sea that day. :-( (RIP) After we cleaned everything up and checked her over, everything seemed to be OK! (I told you she was a good boat)  We grabbed a mooring ball so we could decompress and talk about what happened and what we could have done better.

After decompressing for a bit we decided to take advantage the weather window that was upon us and headed off to Port Townsend to get a slip for the night.  We wanted to haul her out and check the keel, rudder and prop before heading across the Straits and to the San Juans the next morning.

The guys at Port Townsend Boat Haven were great!  They took us in early the next morning and we hung in the sling while we checked out her hull.  And like, I have said before, she’s a good boat (this is a recurring theme).  No damage to the rudder or prop and minimal damage to the bottom paint.  Thank goodness for her modified full keel! We planned on hauling her out anyway this year to do the bottom paint so we were happy campers to say the least.  To make our experience even better, the guys at the yard informed us that they were having 50% off all haulouts that day!  Seriously???!! Sweet!  We told him, well, for that price, let’s do it all over again!

After we splashed, we headed to the fuel dock and filled her up and we were off to Westcott Bay on San Juan Island to meet up with our raftup!

Things we learned from this experience:

  1. Deep Playa: can be translated to “deep beach” in Spanish; the irony is not lost on us
  2. Move the bulkhead mounted depth gauge to a visible location
  3. Don’t get cocky and too comfortable even if you have been successful at doing [insert verb] in the past.
  4. Patrick and I make a great team and work well together under pressure. We didn’t yell at each other nor place blame for mistakes. We both had our responsibilities to take care of and we trusted each other to handle them efficiently and effectively. (It’s always nice to reaffirm this belief)
  5. All sailors will respond to this story in the most positive and comforting way: “See, it was a great learning experience for you two!”

So much to learn…. so many tools to buy…

Posted on Tue 17 March 2009 in Boat Shows

Seattle Maritime Academy Slug: so-much-to-learn-so-many-tools-to-buy Status: published

One of the things about making this decision to go cruising is all the cool stuff you get to learn.

Tonight was the last of our Marine Diesel class at the Seattle Maritime Academy. The class was 11 weeks long (roughly) and was about 1/2 rambling lecture and 1/2 hands-on completely unguided lab work. The class could have been much better run and organized but in general coming out of it I feel like I know a lot more about Diesels to the point of being knowledgeable enough to do some of my own work, to have an informed conversation with a mechanic and to have a sound basis for doing research to figure out how to do things I can’t do right now. I’d give the class a C+. I' was going to go lower, but I think the fact they actually have smaller diesels (like we have) was worth the C+. So it was passing, it accomplished the goals, but it also had a lot of wasted time. Judging by the amount of people who dropped out and frequently didn’t show up; I think many might score it lower.

One of the big outcomes of that (and of the Brion Toss Rigging workshop) is that I put together a big tool order tonight and will stopping in to get some Craftsman toys tomorrow. I like Craftsman tools, I’ve never broken one yet, they are reasonably priced and if I did break one they’d replace it! Did you know on www.Sears.com you can order things and pick them up in the store? Very handy and saves shipping since I wouldn’t have been saving sales tax. I’ll post some list of things and pics of things when I do a full tool inventory.

Next on the course of learning is the Mahina Offshore Cruising Seminar 4 April 2009 in SeaTac, WA. I have good things about this seminar, I’ll let you check out the site yourself and I’ll post more when we’re back.

We stumbled on to the upcoming Mahina seminar because we’re also going to the Strictly Sail Pacific show in Oakland, CA 17-19 April 2009. I didn’t want to invest a whole day in SF on the one class so taking it here in Seattle is ideal! We’re very stoked (they say that in CA right?) to be going to the Strictly Sail show as we’re going to also use the time as a little mini-vacation as well. I’ll post more about that when we’re down there or when we’re back.


Flu Impacts Productivity

Systems - Hull, Systems - Plumbing Slug: flu-impacts-productivity Status: published

Two weeks ago I took off work on Friday to work on a bunch of projects one of which included using epoxy and I wanted to take advantage of the warmer weather and have an extra day to get things done. That Friday went pretty well and I worked on cutting the hole in the cabin top and sealing the edges with epoxy so I can install the mushroom vent for the composting head (more on that to come) but about 11pm that night the Flu (or maybe food poisoning) hit me and I was down and out for about 4 days. Well this weekend I’m feeling much better and Dawn and I are ready to tackle the to do list. Here’s the goals:

  • Finish Installing the mushroom vent in the head
  • Wire up the DC power to the fans in the composting head
  • Change the Oil, Oil Filters and Fuel Filters, remove sediment and water (don’t think we have any water) from the RACOR catch bowl
  • Check the Port water tank for a leak. I think one of my fittings is leaking :-(
  • Check the Propane tank overboard vent – I’ve not expected this since the purchase. I want to make sure its not clogged or broken
  • Secure the Plumbing – All of the plumbing is working great but all the lengths of hose need to secured under the salon floor. Not hard, but time consuming since the work space is so confined

That list feels a little ambitious, but I think we can get it done. I have a bunch of pics from cutting the hole in the cabin top for the vent and I’ll take some more as I get everything installed and do a write up about the installation process.


Installation Weekend

Systems - Electrical, Systems - Entertainment Slug: installation-weekend Status: published

This past weekend was a good one in terms of getting things. It started out with a personal economic stimulus package when we dropped some coin at Fisheries for supplies. Mostly I stocked up on spare filters, electrical wiring components and 100’ of wire I’ll use when I put in the new speakers that I bought elsewhere, more on that later, here’s what did go in this weekend.

LED Lighting LED Lighting

When we were cleaning the boat this summer we pulled out the reading lights in the salon. We didn’t like how they looked, some of them didn’t work and they were a bit rickety. At boat show this year we looked at all kinds of lights some with built in LEDs and other that could take an LED bulb. There weren’t as many choices as we though there were going to be, and in the end we ended up going with two lamps from ABI. One is a classic bulkhead bell type reading light and the other is similar but is mounted on a swivel, like a podium microphone.

For LED Bulbs, we chose Dr. LED bulbs for these new fixtures and LED replacement bulbs for all the existing reading lights as well. The Dr. LED bulbs put out a nice light and they aren’t nearly as hot as the old bulbs which were so hot you could burn yourself on the fixture when pointing the light. They’re a tad expensive (ok a lot expensive) but they also reduce the energy we use which means running the engine less!!

Sirius XM Radio Antenna Sirius XM Radio Antenna

When I put the new stereo in this summer, we were using the little hockey puck style antenna which we ran through a hatch and let it sit free on the cabin top. The new antenna is a Shakespeare SRA40 which I have mounted temporarily on the dodger hand railing. Eventually I plan to relocate this, the C.A.R.D., and GPS antennas, which are mounted on the other side of the dodger, to the mizzen mast or a stern mounted antenna pole. I’ve not decided yet. I think the Mizzen mast may be the only option give the mizzen boom’s swing through the stern area. I’ll decide all that when we starting working on the rigging and hauling the masts. I think the radio already holds the signal better and we’re just sitting at the dock.


We've lowered the property value on D-Dock

View from the cockpit

We made is safe and sound (no pun intended) from Blaine to Ballard this weekend. The first three or four hours of the trip while we crossed the Alden Banks and until the very northern edge of the San Juan Islands we're pretty unpleasant. The seas were very disturbed (i.e., going in all directions) because of the 4 foot swell out of the N and the 1-3 foot wind waves out of the South. It us made us buckle down a bit and get serious about the trip which was good. At that point we were preparing ourselves for a repeat or worse as we crossed the Strait of Juan De Fuca. But as we we enjoyed the peaceful coastal waters of the San Juan Islands and entered the strait, we were pleasantly surprised that the water was calms as could be. You seriously could water skied out there. To top it off the sun was out a bit; it was still a little chilly but nice to see the sun just the same. We spent the night in Hudson Point Marina at Port Townsend and had a nice walk around the town, some wine, some food. Port Townsend is a great little town and one I look forward to visiting again.

Sunday we departed for Shilshole and actually sailed for a few hours, but the winds were light and we were on a schedule so we fired up the iron sail and motored into Shilshole Bay Marina. D-Dock is our new home temporarily while we wait for a permanent slip. We may need to sublet again or move around the sound, but for now until the end of August Deep Playa is a scant 15 minutes away as opposed to 2 hours!

Sunday we stayed a The Dinghy (our condo) but Monday night after work we visited Deep Playa to have dinner and we had our first visitor. Our friend Anna stopped by and shared some wine and food. It was great to see her as she will be soon leaving town for a few weeks. So now we have a guest book photo set on Flickr, hopefully you will stop by and join Anna's photo in the archive.

With the boat closer to home we can focus on the chores to be done, first and foremost ripping out the toilet and holding bag (yes bag) and putting in the composting head, more to come on that for sure!
