Gotta disagree Manie. The crew at the time were in a better position to assess risks and skills than anyone on this forum. They thought they...
Thanks Eralnd44, do you know if this is based on bridgedeck clearance, or downflooding or something else?
I may not have been very clear on this - The narrow bows means that i have less pitchpole stability than a typical 12m cat, so my sail carrying...
Thanks Alik. A solid reference is great. 1/17 puts me a little on the low side. Upping to 0.7m sounds feasible. I don't think downflooding is...
The pod can accomodate taller hulls - I just want to avoid increasing freeboard for the sake of it.
Thanks for the reply. There is a bit of a dearth of pod cats out there. I'm aiming for a more modest beam - the very narrow hulls reduce my...
When is low hull freeboard too low? I am currently desiging a small sailing catamaran suitable for cruising, including offshore. Because it's a...
Very true. I would expect at least 25hp in an average 40 footer and 40hp isn't excessive. I would assume there is a low drag configuration for...
I don't think anyone has yet mentioned out the easy way to produce thrust to windward, at least in a sailboat: Use the keel. Motor and/or sail...
I agree for a typical fixed propeller thrust won't increase nicely as speed goes down, but surely a big variable pitch prop is a better solution...
Jonr, force and power are not equivalent. Power = force x speed So you only need 50hp if you want to make the full 6knots into the wind....
This has to be the most interesting project thread I've read :) Fantastic project Jeremy, thanks for sharing it with us.
Apologies in advance for slight thread hijack. Is there a good insulation alternative that is lighter than Armaflex for those of us who have to...
I find it curious that BS1088 has no strength specification. The local (Australian) standard AS2272 has minimum strength requirements (F14) as...
Aerodynamically, best bridgedeck is no bridgedeck. The only use I know of for bridgedeck sail interaction is having a low boom and using the...
The crew and passengers did a good job by all accounts. Follow up stories seem focused on SAR delay, but I'm more curious about the sinking....
Thanks for the input Korvasieni, I'm just about to read the link you posted. The more I research the more I think that the capability of any...
Very cool design, it looks both efficient and easy to handle. I can't understand why people are so anti anything unusual in rigs, as in my...
The aust ultralight federation has an excellent materials section on its website, http://www.auf.asn.au/scratchbuilder/contents.html most of...
Mainly, why not? It is slightly less efficient than a single rig, true, but the difference is smaller than many other refinements that cruising...
