Re: Pros and cons of steel sailboats
Bob I think your still being an Aussie at heart explains everything. For BS everything you think or say is just upside down for him. Different perspective for him. Too bad as I still think it would be fun to know more about +/- of steel construction not just hear repetitive diatribe about origami. Spent last week ghosting in light air. My SA/disp is adequate so didn't have to run the iron genny that much. Admiral wanted to go slow and chill so set them and forget them. Still, wonder about issues in designing a moderate to heavy displacement vessel that retains the ability to perform in the light air all too common in August on the east coast while remaining able to tolerate the weight us cruisers carry along. My slip mate is in an IP. I weigh a bit less but loa the same. He seems to need to power most days. Admittedly, I'll tolerate 4-5kts sog as long as I don't hear an engine and he won't tolerate less then hull speed from what I see. Is just sail area? What makes for a slippery hull? Is it possible with origami? From what little I know that's the limiting factor in origami. You can't get fully developed shapes so other hulls be they in steel, glass, wire reinforced cement, what ever cannot be as "slippery" in an origami shaped hull. ?I s my thinking wrong in this?
Also note in past have had boats that perform better on one tack then the other. Assume they come out of the mold symmetrical. ?Why does that occur? Look at the bottoms-same number of thru hulls or other sources of drag on both sides, boat floats on it's lines. Don't get it. Doesn't happen in current boat. Read the Metal boat discussion about inability to control details of the folds in origami. Does something similar occur to GRP boats over time?
