There you go - you have been a composite boat builder - epoxy/glass over a wood core!

Ya I like solid composite core for a boat bottoms. epoxy over wood good for a lake not the ocean, stronger and lighter the soled glass but soft core is good for a race boat only, foam, nomex, nita, dvinacell and so on.. just not that good...
Just a side note on a second + to being solid. know why a bertram rides the way it dose? for the same reason a 4000lb full size car drives like you floating on a cloud. its heavy......

You can fight the over flow of endless data on bum cored hulls that gets added to daily by owners. Or read the data packaged for you by the boat builder they have no reason to lie.


you know why light weight is soled to boaters? Simple if you tell a buyer the cores cuts down on costs and build time, by getting rid of 90% of the resin and fiber in place with foam you can cut with a plastic knife. you know say what use to take 4 guys 2 day to cut and lay fabric, now takes 4 hours to lay in the dry fiber and set the bag on the mold and pull vacuum.

Put it like that and it seems like its just cheep, and it is....

Hi,

When you get the time to have a break from a few beers and your obvious self appreciation society promotions you might want to add Geography to the NA Skills I suggested earlier.

Germanisher Lloyd and Lloyds Register of Shipping are two completely separate and different organizations.

LROS is also not the same as Lloyds Insurance Co.

Germanisher Lloyd are amongst other things the worlds foremost composite classification society. They have by far the most skill and real life experience in the use of these "exotic" materials and methods.

Germanisher Lloyd as the name might suggest is head quartered in Germany, when looking at a world map laid out flat ( the earth really is flat you know) it is a bit to the right of England , behind Holland on the other side of the blue thing which is also known as the English Channel and North Sea.
