OJoe!
Joe:I am not sure how the H'34 is set up but our 1985 H'31 has a lazarette under the helm seat. I placed the compressor on the starboard side of the locker. Plenty of air circulation around it. I then built a fence out of polyboard from TAP Plastics. This keeps the fenders, anchors etc from comming in contact with the compressor. By the way, we went with a Technautics Marine unit. It is their coastal unit that is DC powered ONLY. Their newer Cool Blue units are one of the most efficient units on the market. They use a holding plate.
