So c'mon boys which is it Hygroscopic,Hydrophobic,Hydrophillic? and yes I knew it was banned after I tried to use it in the early days of windsurf racing (It was ok in offshore powerboat class racing.).

Used to sail a boat called Hydrophobia, but if you sail with someone called Raby*...

it was a quick un too. Perhaps this is why





* being afraid of water is a symptom of rabies

The old AC boats for a while used a sticky-back plastic with grooves, carefully applied so the grooves were at 90° to the predicted water flow. I think the groove size was the same as 400grit sanding.
I don't think you are allowed to sand the hull finish of most one-designs - ( def not lasers ).

If you score the bottom of your EPS with a Stanley knife in the right directions you will thrash those Miracles and Solos once and for all ... I recommend deep scores 90 degrees to the water flow. Best achieved with a rusty blade, remember always cut towards yourself and use your thumb to mark the point where you want the score to stop ...

How can you say that? Totally illogical, l

Wrong as usual. It's perfectly logical.

Because when one person does it, to compete everyone else does it too and we are all back to square one, but poorer. The only one who gains is the person selling the stuff. Where is the sense in that?

The idea (for most of us anyway, we know you have special needs) of a sailing race is to be better at the sailing. It's not supposed to be like formula 1 where an army of techies spend millions making one car go imperceptibly quicker than another. We don't care. We just want decent racing - racing that is about the driver(s) not the vehicle.

Furthermore, how easy will repairing a golf-ball surface me when some muppet sails into you or you get shore-dumped? Clue: next to impossible. So budget your insurance costs increase several-fold, as every decent bump creates a hull write-off. No thanks.

As my dad used to say, when you can come ashore and say you got the start, every tack, gybe, wind shift, sail-trim adjustment, hoist, drop, mark rounding perfectly right, then perhaps you could spend some effort on that. But if you get all those things right, you will win by so far anyway, you won't need to bother.

You can sand most one designs - it is just a few SMODs that have such daft rules.

I've had to sand my 30 year old Lightning to try and get the worst of the gouges out. Maybe leaving them in would have been fast?

Actually, I love a smooth bottom... but enough of that kind of thing - back to boats.

You do know Mark made that bit up about his 'tache?

Hyrdophobic substances repel water

The difference between hyrdrophilic and hygroscopic is a bit subtle- but "hygro" relates to moisture whilst "hydro" relates to water.

Racing is about going faster, faster through efficiency, faster through guile, through skill, through intelligent action.
If that were not the case, why buy your book?

If someone buys your book, to follow your fuzzy logic then everyone has to buy your book, what's the difference?
Buying a book or sanding a hull, or buying a spray can full of go faster fairy dust.

There is just so much hypocrisy in sailing you can do this but you can't do that or we'll all have to, shut up will you?

But isn't that for the class to decide what they can afford, not the ISAF? Those Merlin folk are loaded...
