Positive buoyancy is great insurance, but like most, we don't want to be in a position to collect!<br /><br />Shoal form stable boats get away with a lot lower ballast totals, too, which really helps.<br /><br />BTW, In terms of R value, our ply/foam/ply decks have been 2 1/4in thick with 1 1/2in foam between cedar 2x framing. Dew or frost quickly evaporate off the framing, and quite a while before off the foamed areas. Pretty dramatic demonstration!<br /><br />Dave ZDave Zhttps://www.blogger.com/profile/13241033623115158564noreply@blogger.comtag:blogger.com,1999:blog-3252341255542272869.post-32356052218806437322016-10-13T19:32:57.453-07:002016-10-13T19:32:57.453-07:00Well there is one other benefit to the foam.

I was reading some regulations about minimum flotation required in home built boats, and realized that the foam made boat the buoyant enough to prevent sinking even if holed. Not that I want to be holed, but it is nice to know the ship won't be going straight to the bottom if something happens.

Most of the year it's not needed where we are... any fire kept us plenty warm on LUNA (1/2in walls) except for a handful of days below about 20degF (-5C or so), when we'd stoke it up.<br /><br />What tipped the decision for us was that, in older age, getting wood in will likely be more of a challenge. Being able to tick the fire over on the coldest days will save fuel when we need it most. But our winter on ME should have clued us that foam is luxurious overkill... not wasted, once in, but hard to pay for the construction time.<br /><br />In SLACKTIDE, we built the sides all at once, with foam framed, foamed and faced before erecting as hull. In WAYWARD, we hoped it would be quicker/easier to back-fill the spaces. In some ways, it was, but the savings were slight. <br /><br />Overall, I think I'd rather lay in that extra wood, now and then, and get sailing now!<br /><br />Ah... sarcasm. Hard to be sure, sometimes, so I over-explain by default. Treat every question as serious. Bad habit, Anke says. 8)<br /><br />The deck 'iron' is cast bronze salvage; a gift from our host. It had been brazed to a steel column. We built the outer stack/cap from copper off-cuts from the sides (lotsa uses for that stuff!). The inner stack runs to the inner top of the bronze casting, snugly fit under a cuff of flashing that then folds over the bronze rim. The outer fits over both. Smoke, then has no chance to blow back down through any gaps, a problem we've had on other installations.<br /><br />May I just say that POP RIVETS ARE THE BOMB! Can even get 'em in copper!<br /><br />So far this is the best system we've managed, though I'd like to do a better job with the fold at a real sheet metal shop.<br /><br />If I get back to posting, I'll be doing one on this whole bit.<br /><br />Dave Z<br /><br />Dave Zhttps://www.blogger.com/profile/13241033623115158564noreply@blogger.comtag:blogger.com,1999:blog-3252341255542272869.post-38798881981029136262016-09-07T10:30:11.671-07:002016-09-07T10:30:11.671-07:00I worked out the R value of 1 1/4 plywood to be ab...I worked out the R value of 1 1/4 plywood to be about 1.5, while a 1/2"ply/1.5"foam/1/4"ply sandwich should be about R8.5. Do you see any other benefits other than lack of condensation on the better insulated walls? I forgot to put the sarcasm tag around the skeg comment, you actually explained it pretty good in the write up. I am interested in how you did the deck iron for your chimney though.

No air space.<br /><br />We noticed on LUNA that we got lots of condensation on 1/2in ply walls, but little to none at the buttstraps, which doubled thickness to 1in. In ME's case, the walls are for the most part below windows and generally low in the hull. Warm, moist air rises above them, further helping reduce condensation.<br /><br />The logs under WAYWARD are temporary. Our host is a heavy power equipment operator par excellance, and he REALLY wants to launch us. So the logs for the launching sled. <br /><br />He'll drag us down to below the tideline, where we'll remove the cross beams. Once floating, we'll roll the logs out from under us.<br /><br />What could go wrong? 8)<br /><br />Dave Z<br /><br />PS. We're hoping for a draft of 1ft, but can take 16in in stride. After that, we'll start dragging our aft transom corners when heeled. But its about 11K @ 1ft and about 17K at 16in! Big diff!Dave Zhttps://www.blogger.com/profile/13241033623115158564noreply@blogger.comtag:blogger.com,1999:blog-3252341255542272869.post-14043797024402826842016-09-06T16:57:52.167-07:002016-09-06T16:57:52.167-07:00How did the walls on ME go, a laminate of two ply ...How did the walls on ME go, a laminate of two ply sheets, or with air space between? Also, what was the final on your chimney? Those big round wooden skegs should help protect the bottom, but it doesn't look as shoal draft as I expected:) Dennis Dhttps://www.blogger.com/profile/04525900170454935174noreply@blogger.comtag:blogger.com,1999:blog-3252341255542272869.post-3818907089081936102016-09-06T13:03:12.069-07:002016-09-06T13:03:12.069-07:00Hi Alan,

We are keeping all spaces on Autarkia open to the boat's interior, including under the side, fore and aft decks. No deck hatches, and any ventilators I may put in later will be doraded. Mold can be a really big issue here too. We are going to count on our woodstove to keep things dry too. <br /><br />Love that dory! Keep plugging away, and post when you can. We love to see how it is going and hope that luck stays on your side. Wayward is looking great!Alan Joneshttps://www.blogger.com/profile/17633386901505182550noreply@blogger.com
