Re: Sail Trim

Do you mean more hydrodynamic lift on the keel?

This is an important aspect of boat trim many people miss. A slight rudder angle makes the combined rudder/keel act more like a wing, and produce lift to weather. Without any weather helm, the boat might feel well trimmed and seem like it is sailing well, but will be making too much leeway.

Too much weather helm, and the rudder turns into a brake, and slows the boat.

Re: Sail Trim

Very interesting! I knew that leeway is what turns the keel into a wing, but not that rudder trim was involved. Thank you!
