We have just purchased a Beneteau
First 47.7 and it will need the teak
replaces in a year or so. I am interested to track this topic as I hope to learn from your experience. Also watching the fuel tank
conversion thread as well. Farr designed the boat so it may be possible to get what you need from them, Just a guess.
If you don't have any luck then perhaps the age old method of cardboard or ply templates will need to be employed.
Hope you find a cost effective solution as some of the estimates i received prior to the purchase
were 30k and above.
