I ordered one at iboats.com that was specific to the year and model of a Stratos I had. They had a lot of patterns available and 3 or so material choices as well. They are an outlet for one of the big custom supplier's. For long trailering trips you do want a custom fitted cover made with a pattern specific to your make/year/model for the fit it provides. You might look at options at iboats, but they are obviously only one possible source.
