Re: planning to buy: steel hull / wooden deck
A wooden deck on a steel hull is a big mistake and a huge maintenance problem down the road. With wood swelling and shrinking , and steel stable, there is no bedding compound in the world which will keep it tight forever.
I have heard the coast guard had good luck with steel hulls and aluminium super structures, bolted on. I' d prefer to make the transition at the cabinside -cabintop joint.
With a wooden deck you lose the huge advantage of metal ,the ability to weld things down, the most reliably watertight and super strong connection possible.
