restoring a sank boat, questions

Hello, I am trying to figure out if the hull of a 1987 luhrs Alura 35 is a 'cored' hull. This boat sank, and, I'm considering a restoration, and would be very hesitant if it were a 'cored' hull, due to the fact that there is no way to get the water/moisture out. Is there any easy way to tell? Thanks, Mark

 

Take off a thru hull fitting and dig around a little. Sam

 

the hull is not cored, but they did use coremat to help with print thu after the skin coat , but like sam said check a thru hull cant hurt

 

Thanks,

Ok, not to sound stupid....what is coremat, and 2what is print, the rough surface from the fg mat? Also, how do you know the hull is not cored? Thanks

 

Also, someone told me that the hull, above the waterline is cored, any thoughts?

 

if its like the 28 the hull is not cored it dose have coremat to aid with print thur so you dont see the checker board like older boats , and it dose run from the water line to the top of the hull , but its only 2mil or 3 mils thick and its a fiber not wood

 

Print through is when you can see the fiberglass weave through the gelcoat. Coremat looks like thin cardboard in the layup. Even if the boat has core above the waterline it will take a long time for water to penetrate it.
