Re: I'm never again owing a boat I can't haul and work on myself.
I worked at a boatyard and when I'd spend the time doing the types of things to care for customers' boat that the OP mentions the bosses didn't like the time I put for it on my time card, and hated having to explain it to the owners. One fall I inspected the boats as we hauled, prepped and stored them for the winter and made a list for each boat regarding work that could be done before spring. i.e., replace worn belts, cracked hoses, free up stiff seacocks, correct poor bilge pump installations, etc. I thought it would be useful to schedule the work through the winter and that the bosses could make suggestions to the owners based on the lists, keep us all busy and efficient maybe.
They threw the lists away.
