Bomar hatches
Marc,I have a 1983 H31 and also looking for a replacement hatch. The cutoutopening on mine is approx 19 1/2in x 19 1/2in. This Bomar hatch modelnumber is C139-MED-STD-S. The C150- -std-s is almost the same model.Either would work on my boat... but the cost is anywhere from $850.00to $1070.00. The best price I have found so far is from Redden marine.(I think their wed site is www.reddenmarine.com). Also these hatchesare from the Bomar 100 series... Good luck.Eddie
