My boss told me to find information about yacht service cost per year. For example for yacht 1) Steel 1970-1980 years 2) alluminium 1970-1980 years 3) Plastic 1990-2000 years I've read the small article that steel is the best and cheapest for service. Could you tell me please where could i finde this information? p.s. My boss choose one plastic boat 1994 y.
There are many variables in your question. Strength, weight (fuel economy), corrosion resistance, original build quality. You won't find many large yachts from the 70's made of plastic or aluminum, nor small yachts made of steel.
