In my experience you’re screwed. It won’t work.
Can you elaborate a little more?
I’m back from traveling and on a pc keyboard so I’ll elaborate.
The whole thing is to make 2/3rds of the boat water free such that the boat floats high enough to A) provide some floatation and stability when making an unassisted water entry (ie cowboy or paddle float entry) …B) float high enough to keep some of the waves out when you are inside and pumping…C) keep enough water out so the assist boat kayaker doesn’t bust a gut lifting the thing during an assisted rescue. … Likely a 10 ft boat like yours is most likely 2/3rds cockpit and foot well.
Your boat is mostly cockpit. Getting enough pool noodles stuffed in under the deck to exclude the water will likely eat into your leg space. Pool noodles are round. Round against round forms little voids. Unless you really jam 'em in and “square 'em up” removing the voids. You will know if this works when you try and get into the swamped boat and it just rolls over on you. You’ll know when you get into the flooded boat and the cockpit combing is at or below the waves. By all means though add some floatation. The hatch, the recessed gear deck aft and cockpit size will work against you in float bags and pool noodle volume. I’m not sure you could find a float bag to fit your under deck dimensions. If you look for one remember to get a size larger so it presses against the boat.
The best way to empty a recreational kayak during an assisted rescue is from amidships. (the cockpit) if you are an assist boat come up beside the cockpit and lift the opposite side. ( I find this side easier) Just ease it up and let the water slowly work its way out. Try and keep the boat level and move the boat higher, slowly. If the boat has a bulkhead aft of the seat you can tilt it up on the side of the cockpit as described above then work your way to the bow down the lifelines. Oh that’s right, most rec, boats don’t have lifelines. Note, rescue kayaker if your rescue boat doesn’t have a skirt be careful not to swamp the rescue boat with the water from the swamped boat. Of course if you’re in a high side rec boat it might not be a problem. Here is a video link. Note he gets the paddler in the boat with out a paddle.
If you are alone in the water. Go to amidships, the cockpit. Push down on the side closest to you raising the opposite side. Raise it up as high as you can make it. Use the pfd floatation. Pull the boat upside down over your head if needed to get maximum water out then “flip” it back upright. Note slowly lift, slowly drain water out. Once it is right side up, IF enough water got out. if it worked do your paddle float reentry. Here is a video of a Greenland style skin on frame kayak doing this technique. Skin on frame Greenland boats are often made of wood frame. When he talks about 'worse case" that would be your rec boat. But this is the technique…
Now there is something called a kayak sock or kayak condom that fits on the cockpit combing and goes down into the cockpit to keep water out of the kayak. They are rarely used. They may be hard to find. Bets are they aren’t made for your size cockpit. They are mostly a seakayak, Greenland boat kind of thing.
There. Need more?
