Framing Wooden Hulls With UHMW-PE
Wooden boat building, like all construction methods, continues to evolve with availability of skills and materials. But I have to come down against the wholesale replacement of bent oak ribs with UHMW-PE. As a semi-temporary sister frame repair in isolated cases, the use of UHMW-PE makes perfect sense. It’s easy to install and holds fasteners[.....]
LOOKING AT STABILITY CURVES
Stability information presented to the public is usually simplified to the point of being useless. When I see a published stability curve like that above, my reaction is “That’s nice and it looks good, but it tells me almost nothing.” It’s a nice graphic but key information is missing, mainly data on the conditions under[.....]
BLUENOSE AND COLUMBIA
Bluenose and Columbia raced against each other in only two races in 1923. Bluenose was then 2 years old and Columbia brand new. Bluenose won both those races but the committee awarded the second race to Columbia due to Bluenose rounding a mark improperly. Angus Walters took exception and left Halifax without the issue being[.....]

Sheerline Problems
Many think the sheer is the most important line on any boat. Get it right and all else is forgiven, get it wrong and nothing else matters. To some extent this is true, this one line in 3D space, must be attractive when viewed from any angle. If it’s filled with humps and hollows from[.....]
Change in Stability with Dinghy Aboard
I’m often asked about the advisability of adding a heavy dinghy stored on the roof, people wonder how much difference this will make to stability. The answer always involves a lot of questioning about the particulars of the boat and load condition. So today I made a study of a typical 1985 “trawler” yacht, the[.....]
