Some things to look for
1)The toe rail bolts tend to leak and discolor the hull liner.2)The fuel tank is molded into the hull which can be a hassle if it develops problems.3)The stock boat came with only 1 battery, adding another is reccomended.4)The iron keel tends to rust and stopping it is nearly impossible. Don't worry about the crack between the hull and keel unless it leaks.5)Water tends to get into the x-braces under the sole and can rot the sole and cause odors.6)The rudder can develope bubbles (separation of the skin and foam) if left in the sun. Paint it white or cover with a white cloth. Overall they are good boats, large and fast for their size. The head is small but servicable if you don't use the shower much.
