Has anyone with a seidelmann 34 (or 37) replaced the center salon hatch. Just wondering if you replaced in kind or used a different model and your experience on removing it. Mine is leaking some, arms corroded and just generally in need of replacement. If you replaced in kind - did you use the curved or flat hatch from Bomar (assume it's the flat cast series 100 (model C150----STD-B). I'm very interested in maybe using the ones from Mariner's Hardware but always liked the security of the double arms when the boat is bouncing and the support under the Lexan in case you step on it.
