looking to crew ''''n learn around boston

Speaking strictly downtown Boston:

You can do it the informal way by crewing on racing boats. Look for a club with an active racing program. Call a couple of clubs and ask about posting "Crew...

Celestial Navigation? Forget it!

I agree that this is a dumb argument.

Consider the following three statements:

1) Celestial navigation is obsolete.

jibsheets while spinnaker''''s up

It''s all about leaving yourself options.

You never know when something is going to foul up and require a last minute tack right before the set, or a quick tack right after the takedown. And you...

Tiny rust spots from nearby grinders

It wouldn''t hurt simply to state the facts to the yard owner. Ideally in person, phone is OK, e-mail or letter is right out. Just the facts, no accusation or request for redress, no hysteria. ...

knock downs

As others have said, it''s much harder to knock down a 34 foot keel boat than a 16 foot centerboard dinghy. And, even if you do manage to get knocked down, it''ll probably pop back upright as soon...

Quickstop COB recovery

gstraub, I had the same concrn you describe. Being used to dinghies, it struck me as a sure formula for knockdown or uncontrolled broach, to try to bear off and gybe with the main strapped in.

Quickstop COB recovery

Thanks both of you for the comments. The "oval" comment is helpful to me, as is the idea of heaving to at the top of the circle and just drifting down onto the victim. Using Quickstop the boat...

what''''s up with sail twist?

what''''s up with sail twist?

There''s another aspect of twist: More twist makes the sail more forgiving of minor changes in apparent wind angle or speed (such as those caused by waves acting on the boat, or by a steerer who is...

Factors influencing boat balance

Thanks much. And without resorting to graphics, too.

Of course you can steer a boat by shifting weight to alter the...
