san juan 7.7
I'am having trouble finding the manufacturer of the mast for a 1982 san juan 7.7. Does anyone know this? I am trying to find dimensions for forestay cable and back stay cable and type of spreaders that are on the boat. All peaces are missing.

Hi SJ7.

I sail SJ23 and have found the folks at are knowledgeable and very responsive. Maybe you can can get an answer there, if not here.

Re: san juan 7.7
Thanks for the site. Figured them out by finding the hypotenuse using length of mast where forestay cable connects and length from mast to where it connects at the bow. Now i have to figure out what Kind of spreaders it should have. Whats the difference between the straight spreaders to the spreaders that angle back? Anyone know? It is a fractional rigg. And does anyone know the equation for finding size of them?

I have a 1979 7.7, i belive they all have the same rig. it should have aft swept spreaders. Where abouts are you located?
