    As ugly as they are, crocs can be a back saver in choppy conditions.

    New Olympic Dinghy Selection

    Not sure why there is a moral debate, for me, it's pragmatic because that's the way bids will be evaluated by the IOC, not on moral or ethical grounds, unless there's a big moral cheque attached. Can a proposed class share the same facilities, courses, and personnel as the established yachting events? If not, then is it yachting?

    C31 or c28r ?

    Yes. Particularly if clearcoated.

    Any experience with the Arroworthy rollers?

    Tthe debate over whether windsurfing is yachting is long over, they have successfully shared courses, rules, regattas, and sailors for decades. Foiled windsurfing wouldn't be that different, just faster and more tech involved. Kiting is where it diverges, imho, and kite foiling as well, particularly when it's dependant on ram air kites for light air succcess. One test might be can the "vessel" safely launch and recover from a standard dinghy facility, in all wind directions.

    Traveler strength over span

    I probably overdid it but the calculated loads for multis seem to climb fast, went with 32mm, need more purchase at times for 1 handed ease. About a 24" span, I think, seems pretty solid to date.

    cost of glue for 2600sq of plywood

    Right, when I have wanted a more waterproof subfloor I have sealed all edges as the sheets are laid with the subfloor glue, just gets messy, use shoe covers, minimize walking, harder on a roof. Could do 1 course at a time, let set up.
  8. Not sure what all the fuss about language is, for the Hawaiians I know, using the Polynesian name is second nature, if not first. They say and think them automatically and when it comes to canoes it's fine, they fit. For multis with different proportionality do as you please, menefreghismo. One can appreciate different aspects without politicizing it. Newick didn't always get volume, rocker, and clearance relationships perfect, tended to work better with larger vessels. His lines changed over time as he learned more, as did everyone. Some of his solutions still work well.

    Nice how he can make hard cutbacks and keep speed.

    545 is pretty good
  11. If you go with rivnut rather than Fleetwood's method (best), is the deck cored?

    How to properly design a rudder cassette?

    Actually it was problematic: post too small, broke, doubled in D and carbon. Also fuse was overloaded constantly, looking to upsize to a 3/8 or + steel pin; total absence of bearings so changed in to a graphite/glass lower and delrin upper; linkage doesn't really like to be tilted even with a couple of universal links: tiller/1/2 quadrant was glued on so couldn't be disassembled/serviced, changed to bolt and key; just replaced the whole thing, hope it works. But conceptually being able to raise it is nice, just think the Farrier design is less problematic and cleaner though I've fixed those, too. Not sure the underslung rudder is worth it, I like the French designs.

    Question for Vegas: any info on relative sensitization between Proset and WEST?

    Epoxy is smelly? didn't know that. Fill the voids? what voids, thought you were putting metal over it all? Are you planning for what if all the metal blows off? If low profile screwed down metal blows off I'm not sure what you can expect from the plywood substrate.

    I think that you are over thinking this. Good that you have looked at the dead weight loads, 2 layers of 5/8" just seems a bit much, adding 1 makes more sense. Building it like a building rather than a boat makes more sense, using standard techniques like subfloor adhesive (big tubes), deck screws if nailing isn't good enough, looking at steepening the pitch to reduce lift if it's flat, protecting the edges with metal flashing maybe backed up with polyurethane caulk bedding where you think it wise, using architectual flat metal roofing screwed onto the sheeting, have a vented ridge cap, closing your soffits in, doubling up your fascia, these seem like common sense solutions in addition to having a proper strapped load path. The ridge strapping common now seems redundant, just don't see that many roofs that fail at the ridge but it doesn't cost much so why not. Using a self adhering underlayment sheet, adding isnsulation and ventilation, these are all standard commonsense approaches short of a building a pillbox or coldmolded boat. But each to his own.

    With all due respect, and I am a metal roof fan also, have you considered what happens to your dead loading? Triple layer of ply because of impacts? There is a tension between reducing overhangs for wind and fire safety and the loss of comfort and shade by reducing overhangs, generally closed soffits improve strength and reduce uplift. Pitch is also a factor. Increasing fascia strength is a cheap way to add strength, rafters also matter, particularly in the tails. Plate tiesare good, H7s are pretty strong, spreading out your nails matters. Industry standard is 4' load path. Best glue is going to be subfloor adhesive for this application, as noted.

    Proset is a bit thinner.
