Hi Ann and Nev,
If I don't take the opinions of the rest of the crew into account, I will hear about quickly - have no doubt.
Here's a question for everyone (especially Ann and Nev as they have the most extensive Tiki 46-specific live aboard experience (in the world, I would figure):
Can 15hp outboards be set up to recharge the batteries to run all electrics on board (with solar and wind assistance)?
The reason I ask is this: I would not want to sail into a nice quiet anchorage and have to fire up a deck-mounted diesel generator.
The thought of an electric drive that can be hoisted clear of the water that can be recharged with a small diesel gen to minimize the number of batteries required is appealing until I envision that gen running when all should be quiet. That said, I would rather carry diesel than gas and it's not like the outboards are quiet. So many considerations...it will end up as a compromise of course and I'm glad we have a few more years to think about it.
Thanks so much for your comments. We hope to be gluing up our backbones this fall and I'm not sure we're prepared to put the tube for the shaft in at this point. We are still committed to a propulsion system that lifts entirely free of the water. We realize we are sacrificing some manouverability with this decision. I"ve read with interest the developments in the carbon foam 3-D architecture that allows for quicker recharging etc. It will be interesting to see what comes onto the market in the next 3-5 years. In the meantime, we'll be cutting wood, mixing epoxy, and sewing our sails. I hope Cynthia and Jean-Paul are enjoying themselves. Perhaps once they have fully transitioned to cruiser mode, they can be persuaded to make a report on their electric drive set up. Their building blog was one we followed from very early on and its nice to see them out and sailing now (Dave Vinni and Beat and the Kittles and so many others also). It's so encouraging to see the piles of plywood and dimensional lumber and then, one day, a vessel floating on her lines.
Ann and Nev,
Budget Boater makes an excellent case for a quiet Honda generator, listing all the systems it powered on their Tiki 30. I'm looking very carefully at that. Tess wants 'some' refrigeration if we are to be liveaboards and we are going to be homeschooling the boys, which means computers etc. When I was in engineering school, I had a professor who claimed his children were allowed to watch television only if they 'pedaled' the generator. Something to think about
