I am looking at upgrading to a bigger bluewater cruiser. I want something in the 42-46 ft range for proper bluewater cruising with the family. I have been looking at yachts and our budget dictates we are looking at a 1980-1990 boat (130-150k).

I know that steel gets rust, alloy gets corrosion, wood gets rot, and glass gets osmosis, and its all about how they have been kept and maintained.

There are a number of nice boats that tick most boxes (they are all a compromise in some respect) but I have always steered away from strip planked with glass over (and inside in some cases) as I see this as no better than cored. This judgement has not been based on any bad experiences other than having owned a glass over foam race boat.

Are there any construction methods (as a method, not based on the competence of the builder as this goes for any method) that you would steer away from before thinking about how it was built?

Keen to hear from the brains trust here

Also if anyone wants to buy a 2003 Jeanneau Sunfast 37...
