Ollie,
A few years back we pulled the teak off Raga’s deck. She is hull 123. After filling all the screw holes we went back fiberglass then Kiwi grip paint for a non skid surface. Are doing most of the work yourself? There are many things to be learned as you move along with the project. Let me know where you are and I will tell what we did. Which may give you some insight on how to proceed.
The nuts holding the shrouds were British Standard Fine on Raga which were impossible to find in the US. Hull 123 was launched in 1973. Only an Englishman in ship repair trade would know that BSF was discontinued in the early 1970s.
Best of luck on your project
George
