I think many people think they can do the work themselves and so save money
because the labour is "heavily discounted" lol
But what bites them in the bum is all the jobs they can't do which they under-estimate, engines maybe, at least the cost of parts
when you have it out and see the full extent of the work required.
Whatever is outside your skill set is going to cost - full price
Invariably what brings you undone is the stuff you can't see, the fractured glass that appears when the paint
comes off, the broken structural bulkhead you find after removing a cupboard. Ka ching ka ching ka ching, the price
Only those with very broad boat related skills, an extensive mates network, reserves of cash, patience and foresight to buy wisely and time on there hands can make it work.
And those folk are pretty thin on the ground.
