Oooops. How old were you when you went down the yellow brick road to Oz?

Re: Pros and cons of steel sailboats

I don't really remember and everyone who knows is dead. I recall seeing a pic of me standing on the quay in Sydney just off the ship and to my eye I would say I was close to 2 years old. I have that photo somewhere and perhaps there is a date written on it.

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?

In all seriousness I have often wondered what having a coating like some of the new non-stick ceramics might do for a hull. I know it is retarded, but I was imagining marine life kind of sliding off of it and the water slipping past it like it was greased....

Re: Pros and cons of steel sailboats

I seem to recall some bottom paints having teflon or something similar in them......... With copper going out in many area's, there will have to be some creative thinking on keeping the crud off the hull bottoms.

Hmm.. actually I did grow up eating it. And by the time I was about nine I couldn't stand even the smell of the stuff (or, even today, the whiff you get from the Kraft factory as I drive down the freeway to get the boat).

Still, it's one of this country's greatest exports, so it can't be all bad.


Next time you have some, think of this... because you're spreading what's left on your toast:

Re: Pros and cons of steel sailboats

THOUGHT SO

Altho it is not a true anti fouling paint per the directions. only for limited use or trailer-able boats in the water for short periods of time.......but it HAS Teflon!

Re: Pros and cons of steel sailboats

Oh, after a few minutes of google'ing I came across this stuff. It is supposed to be a non-stick marine coating. I am not sure if it is a slippery as crisco, but it probably is less fattening. This stuff is supposed to be good for long term and also prevents zebra muscles and what have you.

Re: Pros and cons of steel sailboats

Out:

I think it is pretty clear that you and I like the same kind of boats. I'd be happy to own your boat. I want performance. Some sailors don't know what that means. I do. You do. We can be an "elite" group. I am convinced that when we say "performance" that a sorry lot of crusing sailors have no clue what we are talking about. I will strive to change that.
