Thanks for all the info.
A wee update
Was at boat again the other night and again more heavy rain.
1. Forward cabin no leak and no water moisture when I removed the access panel
2. Aft cabin still leaking – need to fix
3. Salon no leak either
4. Binnacle no leak but did have cockpit canopy cover on. When accessing the panel in aft cabin there cables running down from the binnacle had residual water in them so looks like the screw holes are the problem
So still work todo
