Re: Full or Shoal Keel on New Oyster 575?

There is no substitute for draft.
To say the performance difference is negligable is not correct if you are looking at VMG's.

But if draft prevents you from going where you want to go I would consider that "poor" performance.

I would ask the builder to provide you with VPP print outs, not just polar plots but the entire print out and then you can see for yourself to three decimal places exactly what the difference in performance is. No need to guess. Be scientific about it. Wear a white lab coat. Put something important looking in the pocket.
