My cockpit floor slope is forward and as such doesn't drain completely. Noting that I leave the boat on a swing mooring and with the keel down . I do not lift the keel except in shallow water .
Question : Has anyone filled the floor area with a resin or similar to create a self draining cockpit floor.
My thought is to weigh the the bow down ,then pour onto the floor a filler rich resin Which should self level . Thus when bow load is removed the floor will slope slightly to the stern...
Any similar solutions or ideas are requested .
I have enjoyed the great information on the Forum and have just joined so look forward to continued interaction from my base in Australia.

Hm... interesting, I have an inboard diesel engine so my cockpit is a little backward.
Do you have the outboard motor pernamently attached when you leave the boat?

I suppose that filling the cockpit just with the resin is not really good idea. It will be very heavy and you will have to use a huge amount of filler to not to be brittle.
I would prefer to put there some waterproof plywood with the requested angle and laminate it in that position.

Much cheaper solution would be to install the secondary drains in the opposite direction and connect it to the sink thru-hull.

That's a common refrain from SK owners. How deep is the water at the bulkhead when it is reaching the scuppers at the stern? That of course tells you how much you would need to raise the surface. You could determine the quantity of resin by pouring water into the cockpit from a bucket--that'll also let you estimate the weight based on the density of the resin.

I wouldn't make a solid block (or wedge) of thickened resin--I'd be afraid it would crack. I think I'd pour some in, put a glass mat (or Coremat) on it toward the front, let it partially cure according to the directions for laminating, pour some more, add a slightly longer mat, etc., until you've reached the scuppers. Then finish with some sort of non-skid, perhaps as simple as some sand sprinkled on the surface of the final layer, covered by a coat of two-part paint. (The final mat could make something of a non-skid pattern.)

<hr height="1" noshade id="quote"></blockquote id="quote">I like Tomas' second suggestion. I would just cut holes in the lowest places of the cockpit floor, where the water pools, and install new floor drains there, and run tubing from there to the sink drain thru-hull. It's not only inexpensive and easy to do, but it will also increase the overall capability to drain water out of the cockpit.

Just a thought(although I probably missed something) Wouldn't a cheaper, easier, fix be to take some weight out of the bow or move some ballast around so that the stern sits a little lower in the water than the bow? Or maybe the cause of the problem in the first place is that the boat isn't sitting on her lines. Not trying to be a smart ass, Just wondering.

The boat sits on her lines with people in the cockpit and the keel down, or with the cockpit empty and the keel up. Pulling the keel up moves the COG of the 1500 lb. keel probably about 2' aft, which is sorta like moving five people out of the cabin and into the cockpit. It would take a lot of shifting of "stuff" inside to accomplish the same, and permanently weighting down the stern is probably counterproductive.

The only thing I don't like about adding drains up front is that you're making holes into and through the plywood core. Properly bedded and maintained, or done with over-drilling, epoxy and re-drilling, that'll be OK. It just might not be my choice. But I didn't have a swinger--my cockpit drained nicely through the transom scuppers, so I didn't have to make a choice.

I have a swing keel and have never had a cockpit drainage problem. The outboard is mounted on the stern all the time, batteries in the cabin just ahead of the quarterberth. No other significant ballast.
Were there different cockpit designs on different years of boats?

Our swinger drains nicely to the scuppers in the transom - keel down, 9.8 hp outboard on transom and likewise 2 batteries in the compartment just forward of the quarter-berth, sails in the v-berth.

How much water do you collect? I collect a small puddle about 1/8" deep at the forward end and perhaps1" wide fore and aft. I also have 2 batteries under the starboard settee and a very heavy outboard, but it wasn't noticeably different with my 30 pound lighter 2 stroke. Off setting that is a large, P.O. installed, stainless holding tank under the V-berth.

Good point Dave, I don't have much of a problem, but I have used a squeegee to push the water toward the scuppers for some time now. I reckon if I just put the keel up, I may not have to use it anymore! Thanks for the tip!

Get the Kangaroo out of the V Berth.

Before I would go messing around with resin I would move things aft or maybe some sand bags all the way back in the quarter berth by the transom. Just a thought.

Thanks for many of the comments .
I note that the 30kg motor is always on the stern and the battery is under the quarter berth and the water-tank is on the port side beside the table . There is a standard Anchor in the forward well . I am as heavy as a kangaroo and with me hanging on the aft ladder I drain the cockpit just .
I will cut some 1/8 teak marine ply to the shape of the cockpit with a 1/2 inch clearance at the side . this glued to the sole will provide a gutter for water (The sole is slightly curved to each side )
This should look smart and be strong not brittle and no more wet cockpit sole.
I am impressed by the number and quality of suggestions
Thanks

Okay, do tell. What is "heavy as a kangaroo"? Is that colloquial Oz-speak for really big, or are you literally as heavy as a kangaroo?

The plastic Dri-Dek tiles also work as a floor cover and can be cut to fit like the teak above.
