Thanks guys. It will be very difficult to walk from marina to marina as I am living 300miles away and there are very few marinas in that area. Anyway, I will make a couple of calls.
The model is C&C34. I looked at her thoroughly as it is on the dry and it seems to be in good shape. I noticed some rotten core on the edges of cockpit openings but ... it is 30 years old. There are no "spider" cracks that I saw on other boats.
I noticed ssomething that looks like leak on the inside of the hull. How common is leaking between hull and deck on this model? and how difficult is to fix it?
