Features:

Equipment required:

  1. Mast sideways-tilting system using tackles in the main shrouds, like on a Catapult but workable when fully inverted, using winches and jammers behind the rear beam.

  2. A rope from one end of the rear beam forward through a block at the chainplate, up through a masthead block, down through a block at the other chainplate, and aft to the other end of the rear beam.

  3. A separate inflatable float (e.g. truck tyre inner tubes, a racing mark, a small tender) and means of inflation (gas cylinder, pump) stowed in an accessible locker behind the rear beam.

Method:

1) Boat has capsized. When all the crew are safely on the trampoline they start to inflate the float and operate the mast tilting tackle.
2) Mast is fully tilted. Inflated float is being launched, tied to a line through the masthead block and chainplate block to the rear beam winch.
3) Slack in the float line has been pulled in, moving the float out vertically above the masthead. This line is now being winched in.
4) Masthead is winched up to the float, raising the windward hull.
5) The masthead line to the float has been belayed. The winch is now being used to reverse the tilt of the mast.
6) The weight of the raised hull has righted the boat, raising the mast from the surface. Release the float line, centre the mast, recover the float, sail away.

Project progress:

Trials on modified Catapult late 1996, encouraging results.
