Main Foil Slop Fix

The main foil typically has slop. The bottom of the foil trunk is not tight with the foil. A very effective technique is to tighten this up is to use one side of Velcro tape.

• Obtain 3M black velcro self adhesive tape

• Cut a length of velcro tape that is just shy of wrapping the foil vertical

• Separate hook tape from the loop tape. We will only use the hook side.

• Find on the foil the area where the bottom exit of the foil trunk rubs. It’s usually worn. Clean it (alcohol, acetone) in preparation for a contact adhesive.

• Stick the hook tape on the foil vertical, putting the ‘ends’ at the fore end of the foil. It is ok if there is a gap.

• Put the UFO where you can lower the foil completely, while having the boat tied up (ie: on a dock). The foil will not lower completely, the velcro tape makes it too ‘thick’. Try to lower it anyway, then pull it up.

• Look at where the velcro tape shows damage. “Shave” the hooks in the marked areas with a sharp knife or razor.

• Repeat until the foil just barely lowers into place.

This results in excellent snug fit. Unfortunately, it is short lived -- usually lasts around 10 outings. Once it is worn out it can make lowering the foil difficult so be prepared to remove it.
