OK, I like a hydrofoil on a boat, I have tried the stingray on a 15' boat & it made a big improvement, I now have a 17' Stratos 273 with 115 HP, it came with a poor designed one (Hydro-tail ?). I was wanting to a SE Sport 200 or the 300. Has anyone tried this particular one ? Do I need the 200 or the 300 ? thanks,,GC
