H37c Liner

[Val]

I am considering purchasing a H37c and have a question on the liner structure.A 37c that I recently looked at had a hole in the forward part of the engine pan that went down to I don't know where.Does anyone know what the liner and hull structure is in this area and in general in the aft section of the boat?There appeared to have been a lot of water entry into the boat, possibly from leaking exhaust hoses.I am concerned that there is water trapped between the hull and liner.Thanks,Val

HULL lINER

I sail a 1985 H37C and have not found any areas in the hull liner that collects water. My hull apperas to have weap holes where needed. The pan under the engine does collect water from a variety of entry points. On my hull they came from the main hatch(solved when dodger was installed), a cracked crack in the exhaust hose leading up to the elbow, and from a leaking packing around my shaft. When the boat was sailed with water in the pan, it would leak out onto the sole. The hole you see may be a attempt to divert that water directly into the bilge where the bilge pump will take care of it, instead of fixing the source of the water entry. I check my pan everyday when sailing. Its a very good indicator if anything is leaking and needs attention.

Factory hole?

My '79 H37C has that same hole. And I believe we had that discussion here on HOW a couple of years ago, others had the same hole. The drip from the stuffing box should go under that pan but the spinning shaft will throw most of it on the pan. I solved that problem by installing dripless packing. As Alan said, there are numerous places for leaks that will find their way there. Another one is the pedestal to cockpit sole mounting, easily unbolted and recaulked. Some have mentioned traveler leaks if the boat is old enough to have it on the bridgedeck. Engine leaks and sweating can deposit a fair amount in that pan. You can only do a test sail or have a surveyor find it before you sign any papers. It can be dry, mine is.

These boats don't have true liners.

I do not believe that the Cherubini boats had true liners. They had and engine liner but that was just a way to keep oil out of the bilge.The liners were introduced on the next generation of Hunters. The liner was used in place of glassed in stringers. Most of the production boats use a liner now adays. I'm sure that it is a way to cut down on mfg cost and still provide a rigid and stable hull. When you start looking around you will see Hunters, Catalina, Beneateaus, Bavaria and most of the other high volume boats are using this method. One exception is the Jeanneau.

Hull liner

The Cherubini boats do have a type of liner but they do not have the grid system of the later hunters. The grid incorporates the liner and provides the basis for the structual strength which the heavier Cherubinis have in the hull. The grid on the later Hunters supports the engine, keel, mast and standing rigging. The hull liner on my Cherubini is from gunwale to gunwale from the companionway aft with a cutout area for the engine drip pan. From the companionway forward the liner is from the gunwale to the waterline. There are no stringers in my boat except for the short engine bed. The "floors" (verticle athwartship supports) in the keel area could trap water if the opening at their bottom was plugged.
