Fenn Tarpon S deep seat should fit the bill, if you can find one. Btw, the letters “LS” are used for the name of Fenn’s more tippy spec model, so if you ask for “LS Tarpon”, some may think “LS”, while most would probably know you mean “Tarpon”. The Tarpon S deep seat is much more stable than other spec skis I’ve tried, seat is nice and wide, and as is the case for all specs, they are more durable than ocean skis. That said, smashing waves in shallow water can destroy anything. I bought my Tarpon S new (shipped to US) soon after they transitioned to the “S” version (did not even know that’s what I was getting until it arrived), and soon before the fire. So I’m not even sure if they are making Tarpon S right now. I’m surprised there are not more stable specs out there for those that like to surf on bigger days and maybe not enter official SLSA races. The huge swell that hit Australia a couple months ago had nothing but specs go out to surf. Good luck.
