Dave – thank you – I will follow your advice.
Colin – a very good point – I will be aware of that now. I have noticed that the top gel coat has parted here and there from the fibre-glass moulding in the corners, or reveals of the CB housing. Should I chip back to where there is adhesion and re-coat with gel – or just fill the gaps with epoxy? Have to get the board out this winter and do what you suggest. I don’t think the cracks are dangerous, buit I have yet to float the boat without floorboards to check for leaks.
Cheers to both – Bill
