Richard, yes, it looks quite familiar. I even ballasted mine (650 pounds) to get more of a shippy feel to it. Tony.
Low speed outboards. I built a 24 foot lobster-style boat 4 years ago, and have run it at displacement speeds (say < 6 knots) since then using a...
These were very well built boats, so I agree that the cause is most likely a point load given by the trailer. Nice boats, sail well and handle...
I relied on it, and the boat still floats 4 years later. Nothing's broken. Tony.
I have had a Sun-Mar composting toilet for the past four seasons. Works fine, because I also have an 84 watt solar panel which lets me run a fan...
I would not put any fasteners into a bulkhead from the outside of the hull. With a properly tabbed and epoxied join running the whole...
Gonzo, how narrow is "narrow" in that context? Putting my w/l beam at 3 ft, and the w/l length at 16 ft, that gives a w/l ratio of better than 5...
Well now, here's a seasonal question - how fast is a scalded cat? Presumably we have to settle on units first. How about kittens? Fur balls? We...
Well Gonzo, I used to think that, until I was hit by a gust when running free in my 17 ft modified Whitehall. It took off like a scalded cat, and...
D'Artois - it may be that like the polyester on epoxy behaviour you mention (with which I agree) some polyurethanes do not stick well to some...
D'Artois. What problems have you had getting epoxy to stick to a modern PU (such as PL Premium)? It has worked just fine with me. Tony.
Water addict. Thanks for the comments. The polar plot is exactly the sort of reasonably hard evidence I was looking for. Assuming that the...
Interesting. It may be that some PU glues should not be glued to epoxy, but perhaps the other way round may be O.K. Probably room for a Master's...
D'Artois, what do you mean by "they bite each other" (epoxy/polyurethane)? I made a strip built sail/rowing boat using PL Premium between the...
Nice long message with plenty of good information! I think you did a useful job in nailing the trade-offs with junk rigs. Jester, by the way, was...
The standard work is Junk Rig, by Blondie Haslar and another guy (can't remember his name). If you are talking about small boats, Todd Bradshaw...
Guest 249 - I mean measured in controlled conditions on the water or in a test tank, and not just "go look at any good boat and you will see", or...
"Nominal 45 degrees". Hmmmm. Some time ago I was firmly told in this forum that modern 12 metres can point well upwind of that - 35 degrees off...
Glue for strip planking. I have used PL Premium (a one part polyurethane) for this purpose. It is stronger than the cedar I built with, and...
Thanks PP, but I don't have any problems! The boat is planked now, and I am at the fairing and epoxying stage. If I had thought that scarfing was...
