I'm using my Starboard race foil

I would have thought the SB race foil would be too unforgiving in the ocean??

Neil Pryde Glides are pretty good for cruising. You have three wing options but I don't think you need them all. The medium would be fine if you're not too heavy, and its very stable as well as very carveable.

Im usually an high aspect advocate, but you seem like the perfect candidate for a low aspect / Slingshot type foil. Those do all you want them to, if you ride small sails. Just note that the speeds are going to be about 2/3rds of what you're used to, and the foil is gonna feel draggy because of that. Never the less, its one of the best foils for surfing swells with a windfoil.
