There's a snap dragon that will fit,,, It's a medium deck, but it's the model with more stretch than normal,,the deck has a mesh covered neoprene. I bought one for my Mariner Express and found it fit the larger Coho coaming just fine albeit a tad snug. It's not the standard Extreme or reinforced deck,,the sewn in bungie is stretchier than standard and the neoprene is stretchier,,has a standard neoprene tunnel. It's a good fit. I think Snapdragon recommends the large size but this works.
