#1 Re: General discussion » C&C 27 Cored Hulls? » 2010-07-04 02:07:49

The decks are cored so you have to watch for water intrusion around fittings and so forth.  Worst case that can result in the need for substantial repair (see Black Arts).  However, the damage in my boat was not that severe and repairs were done fitting-by-fitting at my pace over the course of several seasons. 

I prefer a solid hull and would not worry so much about the deck.  To me cored construction beneath the waterline represents the possibility for much greater problems than simply a soft deck.

Regardless a good survey will be well worth the money.

Presently I have a 1/2" thru-hull fitting that terminates in a 1/2" gate valve.  This feeds raw water cooling to the inlet of the water pump.

I would like to change the gate valve to a new seacock (a ball valve with an integral flange that bolts to the hull for added strength and safety).  However, I am having trouble finding a seacock in 1/2" size.  Most (perhaps all?) start at 3/4".  Groco is an example.

Does anyone know where I can find a seacock (with flange) in 1/2"?  I do not want to use a standard ball valve.  Apparently there is a safety issue mating the NPS threads of the thru-hull to the NPT threads used in most ball valves.

I have some portions of my cored deck which are wet and require repair.  The worst is around the stern rail.  At this time I prefer not to go to the expense of removing the deck and replacing the core, but instead will rebed the stern rail fittings to slow down water entry.

However, I am concerned about new water entry through the deck where there are very fine spiderweb like cracks that lead from the deck fittings.

Can anyone tell me if these very fine cracks will allow water entry?

This is a C&C 29 Mark I by the way, so I hope you don't mind but I find the advice on this site very useful.

Thanks
