Bow Reinforcement?
« on: 31 May, 2007, 19:31:48 »
I'm busy on the Contest Yacht Forum Board today! The starboard side bow of my Conyplex 29 has a puncture through the side, half way between the waterline and the deck which originated from the inside hull. I climbed up to the area and found a heavily reininforced area which looks to have been a slurry mix of with epoxy and metal (lead fragments and other metals) mixxed together forming a diamond shape (if viewed looking forward) with a hole drilled through the center where the anchor locker drain tube runs through to the bilge area.

The metal appears to have corroded and pinched off the drain tube (1.0" diameter plastic/rubber hose) and finally the water started to corrode the metal fragments expanding them and forcing the fiberglass section of the hull outward fracturing it. I spoke to a surveyor about this and he thinks it was a reinforcement for the bow area added after the boat was manufactured for ocean passage. It looks to me that it was part of the boats original configuration.

I am hammering and chiseling the corroded metal out of this area and intent to fix the puncture and rebuild the reinforcement area both with West Systems epoxy, adding siminlar metal fragments (Zinc Chromated), and replacing the drain tube.

Does anyone have any info on this area or have a similar installation in their bow? Hopefully, my description makes sense!

Hi Tim, My C29 does not have that hole in the bow. It does sound like it was for a drain. Hope this helps.
Cheers,

HI Tim, It's been a while since I've been back to this form. I was reading your questions and looking at the pictures of your keel and bilge. The bilge in my Contest looked the same as yours. I don't know your location but mine is in Ontario, Canada. The hard winters had taken it's toll on Aurora when I bought her. Every winter the bottom of the keel would crack from frozen water that had entered through the cracks in the bilge. I finally chipped all the crap out of the keel behind the cast iron section. You should see the stuff I found in there, wood, metal bits, old chunks of fiberglass. I think they swept the shop floor and through it in the keel before filling it with resin. Enough of my ranting, if you need any info on your keel let me know.
Cheers,
Paul

Hi Paul,

Nice to hear from another C29 owner, from Neil Young's neck of the wood no less!

 Does the Aurora have the reinforcement as I described? ?The surveyor who looked the boat over surmized the owner most likely added it to sail it from Holland to the US due to the "heavy timbers" still lurking around near the surface from WWII. It's a rather "stout" area; I'd have an easier time chipping out the corrosion if it were made of concrete. The boat still has an SSB antenna and I removed several transducers, their wiring, and electrinc boxes which I could not determine what intruments it may had originally.So it sounds like a reasonable assumption. The last fellow who had the boat told me he bought it off a seafairing man out of New Bedford, actually his daughter who is a Tug Pilot down in New York sold it to him (the fellow had passed). ?So, his assumption makes sense to me.

The resin over the keel has some cracks as well with some rust stains I plan to chip away to ensure all is well, then reseal it. I had the thought to pour some acetone ?in the cracked areas and let it find its way to any hidden rusted area in hopes of cleaning whatever it can and evaporate, followed by a phspheric acid solution to etch any corrosion, then another rinse of acetone, followed by a West Systems Epoxy thinned a bit to seal any fissures that water may find its way to the keel. Then top the keel area with a coating of West Systems. Although, I'd like to get a look at the keel bolts just to know their condition... but hear it would be quite a job to uncover them. I imagine you'd probably have to use a Jack Hammer to pulverize a ll the reisn/epoxy currently sealing them. With my luck, the boat would probably fall off its jack stands and I'd end up in my neighbors yard!

If you could post or send me some pictures of the areas I mentioned, I'd appreciate it. Another suspect area I'd like to compare to another C 29 is the prop shaft feed through through the aft bilge area to compare with my installation. Currently there is a piece of plywood looked to be epoxied ito the hull that needs a little TLC.

Thanks in advance for your help.

Tim
