Step 1: Start
1. Drill with spade bit
2. Screwdriver to remove centre board cover.
3. Length of string for the down-haul
4. New plastic grommet.
5. 2 small stainless steel screws.
Step 2: Drill new hole in centre board cover.
You need to place the new hole in a location such that you can use two securing screws adequately.
Step 3: Tie new piece of rope to top of centre board
Connect your down haul rope to the top of the centre board.
As you can see I simply tied the rope around the pulley fittings.
Step 4: Replace the cover.
To enable a good grip I put some basic knots in the rope.
For most of the time the grip will not be tied in a loop to prevent people getting their feet stuck etc.
