I can see where the safety ama really comes in to play: sailing broadside to big waves -- there seems to come a moment before the windward (and primary) ama...
Thanks for all you for responses. The idea is that it is just the windward hull (ama) that is designed to make use of aerodynamic down force. Not the beams...
How much dynamic lift does a deep V hull produce compared to rounded bottom vertical sided hull when both are heeled 10 -15 degrees? On some of the traditional...
... I have to ask...which way? This "water surface gravity wave effect" more pronounced with less width or visa versa. Enquiring minds want to know,...
It's interesting to see this in the context of the levels of abstraction we are working through when say sitting at the computer. When I get up from the...
More interested in benefits over hull forms not what a certain canoe can and or can't do really. ex. heeling to leeward a round bottom and a deep V and now I...
The simple Plyboats program I have been using for the past 10 years has a similiar function but it really doesn't prove one way or the other in dynamic lift....
I'm getting ready to mess with my Tamanu canoes again after taking a year off of boat building--new boy and so forth... Anyhow, I put up a new page at wikiproa...
I'm wondering what's the practical value has wetted surface analysis here. Wetted surface is responsible for friction, which is significant part of resistance...
The way I see it like anything else it's give and take flatter/hollower sections equal high wetted surface and high planing power round equal low wetted...
... I was already to pitch the simplicity of (1) or (2) but reread the entry and realized you were getting ready to reuse the existing hulls. So expounding on...
One of the big challenges for any of these options is finding good lumber to make beams out of! I had to laminate the 8'6" beams rather than go with box beams...
What does the Woods folding system look like? I have seen the Janganda/Sea Clipper system -- interesting. I will be interested because in the short term I may...
I suppose the woods setup would work for a tri just as well as it does for a cat. The nice thing about building your own is that it will simply be built to...
Im looking at building a asymmetrical shunting proa and have the offsets for it but am thinking to speed things up to build it out of ply instead of strip...
... We are talking apples and oranges here in my opinion. Ply lends itself to square or trapezoidal cross sections and is hard to beat in this venue. As soon...
Here's something I came across on the world wide webs... http://www.youtube.com/watch?gl=AU&hl=en-GB&v=_qeevNSk-7E http://www.dantucker.8m.net/rich_text.html ...
This is interesting from the blog about their failed proa journey (lashings rule!): "After a thorough inspection we have concluded that what had happened was...
Combine your foil thinking into hull form. Can you expand on that? What would be your impression of a lifting hull form then? Note based solely on low wetted...
Great to here from you... mighty silent one. What say you and your experience with your asymmetrical hull proa. Any lifting effect from hull when at speed. A...
If you are looking for s&g panel layouts for a proa; go to multihull.de,look in the proa section there is a complete set of building plans there and it's for...
Certain bare woods do very well in salt water. Teak is of course the prime example since it gets used a lot on boats for this purpose. On my dad's boat we used...
