TRY,
I think I get your meaning.
If boat design was not fun, I wouldn't bother. The conceptual part is the most fun of all, as after that follows hundreds of hours of hard work. The simple pleasure of making a little sketch without regard for how to manage all the owner's requirements, the builder's budgetary problems, the regulatory requirements, the interior designer's demands, etc.
This is fun, a holiday in fact.
All the best, Tad
