Re: Centerboard position - keel/centerboard Tartan 37 upwind

I think you are referring to moving the center of lateral resistance (CLR) to help balance the helm (usually to tame weather helm).

Here is a good article on the subject:

Helm Balance – Center of Effort, Lateral Resistance, Centerboard, Mast Rake - Waves « Jordan Yacht Brokerage

We haven’t found a condition yet that moving the centerboard was the best answer. Adjusting the vang, Cunningham, outhaul and/or reducing sail are our first choices. Since the backstay on my boat is on a turnbuckle and not easily adjustable underway, we might put a couple of turns on it before we leave the slip in heavy air, and have to live with the results. If you have an adjustable backstay, throw that in the mix.
