This chapter provides a rough outline of how to make a basic evaluation of a boat hull.
It does not propose to make an expert surveyor of you, but you can use it as a guideline to try to decide if you even want to invest the money to have a boat surveyed.
Checking Out a Used Boat
One of the major advantages of a used boat, other than price, is that it has been tried and thoroughly tested.
If a boat isn't made as well as it should be, there's going to be evidence of that. The evidence is usually not hard to find if it exists. Chances are, anything that doesn't look right, probably isn't.
If the boat is on a storage rack or a trailer, you have an ideal situation. Start with the outside first and look for stress cracks or any other flaws on the bottom.
It's pretty common to find a few paralleling the bottom strakes, deep in the corners. Just a few is usually not indicative of a serious problem. But more than just a few, and particularly cracks across the strakes, should give pause for further consideration.
Cracks that appear in wide arcs, or in any kind of pattern are even more ominous, and at that point you should either call a surveyor or reject the boat.
Note: Stress cracks are a frequent occurrence in boats. Because of this, I have included an entire chapter devoted to the subject which describes where and why they occur. Read Chapter Seven, Stress Cracks, Finishes and Surface Defects in conjunction with this one.
Boats with painted bottoms tend to show up stress cracks even more prominently than nice, glossy gel coat.
Wet painted bottoms tend to conceal them, so if wet, allow it to dry. As it is drying the cracks will soon start to stand out, if there are any.
Many, many boats have very weak hull sides and deck joints that often result in needless damage caused by even the most minor bumping against docks.
This is really very easy to check. You do it by going around the hull and banging on it with your fist. If its flimsy and shudders when you hit it, then it is excessively weak. If it rattles when you hit it with your fist, imagine what it's going to do when hitting waves.Copyright© 2004 David H. Pascoe
