My experience with a couple of non McKee boats has lead me to believe the water logging is not as big an issue as most people put on.
We redid an old AshCraft copy that was in the weather and full of water for 9 months.
During the 3 months of replacing the floor and transom while in the garage the boat leaked less than 5 gallons of water and the foam area's we removed for various reasons lacked in retained moisture.
Number one, keep in mind there is likely an abundant quantity of glass in that boat making it heavier than you would expect in comparing to other boats.
Any way you can find out what the original hull weight on that thing was?
