but on the bright side, you have other complaints with the boat. A lighter weight fin keel will sail in a more lively way and you can still have an AP that has a tacking function. The Raymarine AP units going back to the beginning of time had this feature, and I'd be surprised if the other leading companies don't have the same function, even if called by some other name. (Even the old tiller pilots ST1000 from the 80's had it).
