Because this hatch cover is no longer available, I purchased the Dagger oval hatch cover and the Dagger 10 inch round hatch cover to replace the hatch covers on my Mainstream Biscayne 14.5, which is the spitting image of the Dagger Stratos 14.5. Since Confluence Watersports bought Mainstream many years age, I reasoned the Mainstream mold was used for the Stratos, or at least as a model for the Stratos mold. The hatch covers fit perfectly, and I couldn't be happier with the fast service.
