<DIV style="font-family:Arial, sans-serif; font-size:10pt;"><DIV>Hank,</DIV><DIV> Do you know how big the shaft is that goes through the top of your hatch? Have you every had to disassemble it ? My hatch is pretty much identical to Gamma's, I'm in the process of cutting in a little viewport in and also that rotating hatch closure shaft / thru hull deal. Seems like at least a 3/4" shaft would be in order.</DIV><DIV> </DIV><DIV>Brian</DIV></DIV>
