At no time have I ever said that a boat has to be heavy to be strong. The fact is that steel is strong but it is also heavy. Aluminium is also strong and it is lighter, about 50% of the weight of steel for similar structural stiffness.

Ganley designed some really nice steel boats. I have a lot of respect for his work. I have only heard good reports of them from owners. Whoosh's is the first negative comment that I have seen.

Ganly was that all too rare character, a designer who actually got his hands dirty building his own designs. Thus they go together far more easily than those designed by people who only draw pretty pictures of boats and never actually try to do what they are asking others to do. They are excellent and practical designs, and I've never met an owner who was unhappy with his Ganley. They are designed with steel in mind ,based on steel working experience , taking full advantage of the material, not a copy of wooden boatbuilding .
