Anybody know how much more (percentage wise) buoyancy you can get from a Tuflite than standard glassed boards??? Given that, could I ride a 6'1" Tuflite in place of my 6'3" regular glassed board without losing paddling speed??? Thanks in advance.

TUFLITE BUOYANCY

If you were a statistician or mathmatics major, you could cal it out.
Given same 6'1" board, epoxy styro at 5 lbs., poly glass at 6.3 lbs.
Besides floating a little better, it's the FEEL of a lighter, quicker reacting board, that doesn't just lay there when you paddle.
Offset by being more techinical to surf, less natural glide, and more often favored by bigger riders.

Using the weights from leed, 1.3 lbs weight difference is about 0.6 kg, which displaces 0.6 litres of water. Given a board of 6' has a volume of about 30 litres give or take, the lighter board would have an equivalent volume of about 30.6 litres, about 2% difference or less than 1/16" of the thickness. So from a bouyancy standpoint there would be almost no difference. The main difference would probably be in the feel of the lighter board (as it is 20% lighter) and in the epoxy stiffness and response. As the board is already lighter you probably don't want to go any shorter, as it would feel like a smaller board already. Anyway, that's my theory, anyone have any practical experience?
You would have to take the two boards to compare. Buoyancy is changed by density and volume of foam mostly. The resultant upward forces, exerted by the water on a submerged or floating body, equal to the weight of the water displaced by this body is what bouyancy is.
Take each board and push it down in a tub of water until the board is just totally submerged. Whatever water it displaces is the volume it has.
If all other variables are the same, as in the exact glass job, riders weight, the liquid it is floating in, the board that displaced the greater volume of water in the tub experiment will be more bouyant.
Two foam blanks of identicle volume and density could have different bouyancy by a heavy versus light glass job alone.
bouyancy can be a positive force(my board nose and or tail is out of the water with me on it) or neutral fource(the board and a good part of me is submerged) and a negative force where you sink.
If you where able to sit on each board in the water, you should be able to tell immdediately of any note worthy differences in the bouyancy.
The advantage of EPS and other non conventional foam products is the density is consistant through out the whole piece of foam.
