Two VERY BIG MISTAKES beginners make:
1. FAILING TO GET A GOOD PROFESSIONAL SURVEY OF THE BOAT, THE ENGINE, AND THE RIGGING BEFORE THEY BUY THE BOAT; AND
2. UNDERESTIMATING THE TIME AND COSTS ASSOCIATED WITH PUTTING THE BOAT BACK INTO GOOD ORDER.
What beginners fail to realize is that sometimes even if someone GIVES you the boat, it's not a good deal. With an older boat that has not had excellent care and upgrading, this is very often the case.
GET A SURVEY, even if you have to fly a professional surveyor in to do it. Then, take a long look at the results, calculate time and materials and costs needed to put the boat in good order, and multiply these figures times 3 to 10!
This is not meant to discourage you, but to encourage you to realistically assess what you're getting into with the purchase.
