Help! My Seacraft sunk!!!

[Fr. Frank]

I have raised half a dozen boats in my life, from 16' to 40'. Take my advice, do NOT tow it submerged unless you cannot pump her out. Lots of bad stuff can happen.

If you can, use a minimum of 2 boats and 4 divers to aid the recovery, each boat anchored fore and aft on either side of the sunken vessel.

If you have a cuddy on the sunken vessel, a twin-sized air mattress inflated half-full provides good lift from in the cabin it doesn't help at the surface, though.

Tied under the hull, inner tubes make great inexpensive lifting bags. Use at least 5 inner tubes and better yet use 7 -
1 at the bow tied to the bow eye,with NO scope
2 tied to the stern eyes, with NO scope on the lines
2 lashed under the hull by 8' of line, fixed about 2' forward of the transom. When inflated, they should be attached so as to be fixed just 4"-6"above the hard-chine.
If you use 7, fix the last 2 lashed under the hull amidships.

If you have transom cutout, you need to lift the stern higher than the bow, so you can pump it out. You can rent 1 or 2 small gas-powered trash pumps at Taylor rental, which makes it easier.

With the gunnels and transom above water, continue pumping until the boat is as high as possible. Tow the sunken vessel in an alongside tow lashed to BOTH recovery vessels, OR astern with a tow line at least twice the length of the vessel being assisted, and a very sharp knife close at hand.

I'll add more later. Start your planning with this.
