You very seldom come out ahead restoring a boat rather than replacing it once one has been water logged or sinks. The cost, labor, equipment and skill to get it on a trailer to fit it alone maybe worth more than the boat as the entire interior usually needs to be replaced and restored. Even renting a pad to store and work on it yourself here at Lake Powell last I checked is $100 a day. Storage in an area you are not allowed to work on it in is cheaper but still $2 a foot of length per month.
