Ok, I've found a early 90's 310 that seems to check a lot of the box in what I'm looking for and has amenities my wife wants. Problem is that it has the shoal draft keel, 4' 3" in stead of standard draft 5' 11". Since one of my requirements is a boat for local racing my question is, how much performance would I be giving up with the shoal draft model?
Shoal draft is a cruiser's option. My experience is that whatever adjustment that you get in your rating will not be enough. Not many shoal draft boats are competitive in PHRF racing. The First series may be an exception but I would be surprised.
