I didn't know the new Hunters have a balsa cored hull....
As the writer said,
"it's about 5/16" thick up at the flange and down to the waterline, cored from the waterline to about 6" from the flange
..." which means only a portion of the topsides are cored.
This is similar to numerous high end boats and done primarily for purposes of insulation and is done for virtually all production boats.
The hull is solid glass
