Well, the Hurricane II Hydronic furnace is pretty nice (despite my current non-start problem). Mine came with the boat I bought so I didn't choose it, but have been pleased with its performance.
A dockmate (same one that lent me the compressor) ended up replacing an 18 year old Hurricane with a new one. Like me, his came with the boat he bought a couple years ago. He could have chosen anything, and has done a number of installed of other systems, but has liked the Hurricane so much that he went with it again.
