Bottom Siders

I wanted to find some ethafoam mats for the lounging pit on the lunar lander project (a house built like a modern boat). I imagined something like the wrestling mats that I recalled from high school would be great. And would be good to work with local company. http://www.bottomsiders.com/
It turned out each 15 square foot cushion would be $1265.00 before tax. That’s $84 per square foot. Yeow. All six cushions would cost as much as a new Hyundai. I have to keep looking.

Trimaran Ferry

Thursday’s job was to create some updated renderings of the 149′ passenger ferry design. They never real till they real, but this one might go. Interesting irony that it might start in Africa first.

I recall that Richard’s excellent presentation on it was soundly rejected by Washington State Ferries some 25 years ago with the words “If it ain’t steel, we ain’t doin it.” Its foam/glass. Aiming for 40+ knots and 2500 hp. 149 seats.

Silverthane

I got to use System 3’s Silverthane polyurethane sealant this weekend, in place of 5200. http://www.systemthree.com/store/pc/SilverThane-SA-2100-c58.htm
It is a 2 part product so that seems to solve my two main complaints about 5200; that my $17 tube hardened in just a few weeks, and after seems like days, the part I sealed was still wet.
I lose 5200 tubes after they opened even though I try to seal them up.
The two part poly self-mixes in a special nozzle. I’m guessing each use ruins the nozzle, so get several if you work like I do, with several small jobs. And my job was functionally cured the next morning, which was the soonest I tried it.

Only comes in white at this time.  So I still have to bear with 5200 for black jobs.

Captain’s Nautical Bookstore

I finally tracked down the book I needed to verify the design rules for the 149′ passenger trimaran. It’s the IMO HSC Code 2000. I faced the expense and the month wait for it to be posted from UK. Then I saw on the IMO website that their publications are also available at Captain’s here in Seattle. www.captainsnautical.com  I had forgotten that they have everything to do with boats there. They are now carrying my Design Book also. (and at less cost as there is no shipping cost)
