Hi all,
I'm planning to install a double clutch on the port side of my 1989 Cat 30 MkII tall rig. It will be mounted on the same raised platform where the clutch for the main halyard and the clam cleat are mounted on the starboard side (next to the hatch top). I understand that I can expect to encounter an aluminum block or plate when I drill the mounting holes. I'll need to use a tap to cut threads in this plate so that clutch can be secured with machine screws. I believe this is the reason Catalina put the plate there to begin with...helping to avoid having to drill holes all the way through the cabin top.
Anyway, simple question: does anyone know the depth of this aluminum plate below the gel coat/fiberglass? Just want to know what to expect when I start drilling and also the length of the screws I'll need for the job.
Still learning the ropes,
Tpoo
