In my limited experience the boat is only part of e conundrum.My last boat I bought in a yard with attached moorings,handy as somewhere to keep the craft is handy.Bilge keelers like the Westerly 26 are easy to store over winter or take the ground on a public hard to fix any underwater problem...
On another channel they have just launched a boat called Yabba……..just looking at the empty cans of anti foul give an idea how much big boat cost to maintain whether maintenance cost can be absorbed by patrons or some kind of business needs to be established
