Anyone know how much gasket material is need to replace all original hatch gaskets on h34. One Forward main hatch, two small hatches, and midsize cabin hatch. I want to order on this sight and but I lost my measurements I took last time I was on the boat. The gasket on this sight is sold by the foot at about $6.00 per foot and don't want to miss order. Like to order it for this weekend project.
