Leaks & Dampness

My RL 24 Mk 2 has a leak which results in saltwater in the stowage area underneath the cockpit floor. It seems worst after fast motoring or when running before moderate seas when a fair amount of water comes up the engine well into the two side stern engine well compartments. The well has been modified, ie cut down, so the side walls range from 10 - 18 cm high. This may have been done to accommodate the 8HP Honda 4 stroke motor.

It seems that there is water in the buoyancy area under the cockpit floor between the transom and the rib at the front of the port and starboard cockpit lockers. Crawling up a quarter berth to that aft rib Iíve found that the low point of the rib / hull is damp and that the flow coat easily peels off the rib. I suspect that this flow coat was applied to prevent leakage as it has been applied externally to the motor well and internally at the furthermost part of the quarter berths, that is where the aft rib joins the hull. Iím getting about half a cup of water per day and Iím concerned about osmosis. Iíve had a blow heater running on the area for a few days but the dampness returns.

I think that, over time, the water came through small wiring access holes from the starboard side engine well compartment into the starboard cockpit locker then seeped into the cockpit buoyancy area.

Before I seal all possible water entry points I wish to eradicate the dampness and ensure that the buoyancy area is dry. To do this I need access to the cockpit buoyancy area. Iím thinking about putting an inspection port in the cockpit floor to gain access although Iím not keen on the idea. Has anyone had a similar problem? Is the buoyancy area filled with foam or is it a void and/or can anyone give me some advice?

My recently purchased moisture meter has identified other areas of significant dampness. These include the rib below the companionway, the keel housing particularly the top (cover removed) and the base of the mast compression post on the cabin sole. Iím also getting readings on other places of the cabin sole which makes me wonder whether there is water between the sole and hull. There does not seem to be any access to this area and I donít know where the gap starts and finishes. (Iíd hate to cut a hole in the cabin floor to find that Iíd cut through the hull).

Any advice would be greatly appreciated.

Water in Buoyancy Tanks
I purchased my RL24 in Brisbane and shipped it to Melbourne. It has an Inspection Port cut in to the Cockpit floor. Yes there is a substantial amount of foam, about 8 inches thick or more, moulded under the floor. The Inspection Port was cut through this. I have found this very usefull because a small amount of rain water seems to leak through the Gunnels and I am able to mob this out. By the way I would welcome any suggestions on how to stop water coming in through the deck and hull joint. There must be some cracks there. I also had water between the cabin floor and the outside hull. I drilled a small hole in the cabin floor, very carefully so as not to go right through, and sucked the water out with a Gally Foot Pump and have never had any trouble since.

water in buoyancy tanks
i had water under cockpit floor about 60 litres on two occations found hull was not joined to deck for about 2 ft.Reglassed the area concerned and put two inspection ports at end of quarter berths in bulkhead near centreline

Thanks Bill & Peter
Thanks very much for the advice. I've just bought a few inspection ports today with the intention of putting one in the cockpit floor into the buoyancy tank like Bill's RL.

My only misgiving was possible damage to the inspection port through standing on it etc. Peter, I would have thought that your method through the buoyancy tank wall would have been difficult installation wise and also the bulkhead would have prevented access to some degree to the bottom of the buoyancy tank.

Bill, where did you drill the hole in the cabin floor? I tried to buy a flush fitting screw type bung but could only find ones with a protruding grip which would soon get broken.Sorry I can't give any advice on the deck/hull leak. Knowing my luck with leaks next time I sail I'll probably find that I've got a similar problem.

Once again thanks for your assistance gents.

Best wishes

Inspection Port and drilling hole in Cabin Floor
Terry, the Inspection Port is situated near the Traveler,so little chance of stepping on it. If you buy the thicker type, they are pretty strong. You will have to file or sand a flat surface in the cockpit floor, for the port to fit on, as you know ,the floor is rounded and the Port will not screw open or close, if it hasn't got a flat surface. As fear as the hole in the cabin floor, I drilled the hole in the centre about 6 inches aft of the keel Case and installed a chrome plated Brass Bung. I had to hacksaw a bit of the outer part of the Bung, because the gap between the floor and the hull in only 1/4 inch. I got the water out by inserting a small clear platic tube which fitted into a 1/2 inch tube and then onto the pump. I moved the tube around as much as I could and managed to get all the water out. The inner Mouldings seem to imbedded against the outer hull with Bog, which in my case has rotted away, very smelly. If the bog is still in place in your boat, it might be difficult to get the waterout, even after ddrilling one or more holes. Hope this makes sense, good luck; Bill Post

Inspection Port and drilling hole in Cabin Floor
Dear Bill,

Thanks very much for the excellent advice on the cockpit inspection port and the cabin floor. After discussions a few days ago with Muir's Chandlery Manly Qld I came to similar conclusions. Your advice confirms their's, consequently I'll do exactly as you have done.

Once again many thanks Bill, your time and advice is much appreciated.

Best wishes
