Hi Gang,
Sally, Congratulations on having the Gunboats use your units. I would have used your equipment on our1990 Catana 42 one side engine replacement but as you know you were a bit out f my price range. I ended up going with an AC34 from Thunderstruck in California. I was able to make a bracket that bolted to the existing Volvo Penta sail drive and it seems to be working out. There are still a few bug but they are all working out. I can get up to hull speed with the electric alone but, as I am sure we all know, not for long. 4 to 5 knots works well and I think I'll be able to get the generator to handle that load if I need it long term. Plus I still have the old Volvo Diesel in the other side. All in all it is proving out for me.
As for the 10 year project, so far I am 17 months into an 18 month refit project. I figure another 6 months and I'll be close. Now a couple sailboat races and race boat deliveries (still need to pay for this) plus taking the summer off to spend some time at home with my wife, have extended this time table so I actually feel like I'm close to my original estimates for the refit. Isn't tunnel vision and the ability to ignore reality great!
Cheers,
Ric
Can anyone point me to a thread regarding propane hot water heaters?

Gunboat is now using the Oceanvolt electric saildrives on their G4. The Oceanvolt saildrives are very state of the art and high quality - so is the G4. If you haven't looked at Gunboat's site, do so. That boat is crazy fast!

The Tang Electric System was put together by Dave Tether who built and developed the Solomons System I have on my boat. Last I heard Dave was not doing it any more but his site is still up.

Don't be afraid of higher voltages (Mine is 144V) on board. This is just like working on an Electric Panel in your house, don't stick your fingers in a place you're not sure of. When working on my pack I break it down to 48V's when I'm doing maintenance. All the High Voltage equipment and connections are in well protected boxes and I know to prepare for going into them.
Jason the Tang wasn't a Gunboat. It was built by TAG YACHTS. It had somewhat of a bad rap on its Electrical system do to many quality control issues with the boat. I talked to Dave Tether extensively about it and he was not happy with the builder. Main problem was the rush job to get it on the show circuit. I have heard of the "dumping power" issue with the 410 though I haven't experienced it yet. It's probably only going to happen on extended cruising times.
Now Gunboat did use the Electric Marine system in their boat "Moonwave"

I believe the boat is in charter now which unless a Hybrid was to be a Captained boat by the owner I would never do.

A couple of years ago, I had the pleasure of talking with the systems engineer for the 60' Gunboat catamaran, Tang! while it was moored in Fort Pierce, Fla. on their recent Atlantic crossing, they had to dump power they were generating so much. So whichever way you go, make sure that regen power flows are considered. You may just have to order hot showers for the crew, twice a day in order to handle the extra power.
Cheers,
/Jason
