I'm getting leaking running down the compression post inside the cabin. Calking around the plate on the deck has not helped. Has anyone encountered a similar problem?

Common problem

This is a common problem with certain model Hunters. First you have to determine if there is permanent damage. Then you have to fix the problem so it doesn't happen again. Do an archives site earch and you should turn up lot's of info, it's been discussed extensively here.

Bad design..

.. as I hade same thing on my 29.5 and aware of many others on HOW with similar occurance. It is due to water passing via opening in the mast wall at lower part, for inner vhf and electric cables to pass thru. This opening should be tightly waterproofed with silicone or similar.

33.5 Compression Post

Steve, I had the compression post on my 1988 H33.5 replaced last year. The wiring harness entry hole beneath the mast became unsealed, allowing water to seep onto the post. The teak/mealamine covering the post became stained and the small irregular shaped piece of teak and holly sole delaminated. After pulling off the teak/ melamine board covering the compression post, I discovered that the entire wooden compression post had rotted and disintegrated. Thankfully, there was no serious problem to the deck, deck core, deck plate, or bottom plate. The yard fabricated an aluminum post and we reattached the teak/melamine covering. I had Hunter fabricate a new piece for the sole. We resealed the wiring race beneath the mast prior to restepping the mast. If you boat is exhibiting signs of compression post leakage, pull off the teak covering immediately. This is the only way, unfortunately, to adequately inspect the compression post. Obviously this was a very poor design.

I had the same problem.

Steve, I had the same problem on my 1989 33.5 and corrected it this last spring. We had the mast down to install radar. We installed a new post using the existing teak veneer, refinished the shower wall with a sheet laminate from Menards, and resealed the wires at the deck. Removing the post is not technically difficult but it is a bit of a jig saw puzzle. If you’re a do-it-yourselfer let me know and I can give you more detail. Charlie Fritts charlie.fritts@gunite.com

More on this

Once you r&r the comp post, you still need to fix the leak. Drill a 1/4" drain hole in the mast step, and put a short length of appropraite sized tubing around the wiring and hose-clamp it to the wiring entry point to keep water out.
