RE: Kombat 107
As Ola has suggested above, to prevent mast impact over the nose, I'd like to recommend the DaKine FW mast pad that you can fix on the mast below the boom with 5 plastic clips. You can adjust it upward or downward depending on the lenght of the nose and the mast-track position, unlike combined T-boom bra and mast pad. It's a bit tedious to fix it on the mast but at least there is very little chance you will loose it during a wash out in waves...
As a home-made solution, you can glue some footpad directly on the nose of your board.
It will surely protect the upper deck, but in case of a serious crash, the bottom of the nose will fracture...(didn't have the DaKine mast pad at that time).
