Good onya. All the best with your boat!
What punters forget with the expression- Take from the purchaseprice
the estimated cost of the repair is that prices are low for used boats anyway and the vendor has "x" amount of inventory that has value.
I have my moments of despondency, but then i have rebuilt my boat from the keelson up. (And down!) Not just a soggy deck repair.
You have got to take it in context tho'.
Disregard the previous negativity, enjoy the journey.
Ah so, you're another one of those timber junkies, like me eh? Goodonya...
