finished board weight?

General Discussion

Hey hey,

I’m curious. How heavy are your boards working out to be?

How heavy do good production boards weigh? Pro comp boards?

I just completed my first two boards using epoxy resin and epoxy clear coat (one coat top and bottom) and they weigh about 14 lbs each.

Board #1 is an 8’6" mini long board w/ two layers of 6 oz glass on the deck and 1 layer of 6 oz cloth on the bottom. Board #2 was supposed to be an 8’0" fun shape, but looks like a big short board. It has two layers of 4 oz on the deck and 2 layers of 4 oz on the bottom.

Thanks,

Oliver

Board 1:

12 1/4 lbs. It is a 9’0" with single six top and bottom.

Board 2:

12 lbs. It is a 9’0" with single six top and bottom.

Board 3:

12 lbs. It is a 9’0" with single six top and bottom.

Board 4:

11 1/4 lbs. It is a 9’0" with single six top and four bottom.

Two boards buckled, one broken, one is still in one piece. All boards approximate weight before wax and fins inserted into the box.

Your weights are fine for a sturdy board for a learning surfer.

When you start making 6’ x 18.5" boards, weight will drop to around 7.5 lbs…

i started making board a year ago. i’m on #12. the first one was a 7’x23" “fish” with xps. it weighs 12 lbs. with wooden keels and lots of experimental glass and reglass. An 8’ x23" eps 3x6 deck 2x6 bottom carbon fiber strips top and bottom = 14.5 lbs. An 6-4 xps single fin= 8.5 lbs. An 6-4 eps carbon fiber all the way around = 7 lb(bad glassing on and did not vac bag) . An 6-2 eps carbon fiber(same story)=6.5 lbs. pulled the glass off my fairly new 9’ rusty desert Island and shaped it down to a 7ft single fin egg with 2x6 deck and 2x4 bottom=9.5 lb.

vac bagged a 6-3 swallow tail 2x6 deck 2x4 bottom eps with carbon fiber strips and epoxy and 4 oz strips between the eps(and a gloss coat). had to use lots of filler after i sanded all the wrinkles off= 7.25 lb. a 5-6 fish 2x4 top and bottom and carbon fiber strips between the eps with keel fins and acrylic coat = 6 lbs.

and for more comparison an old 6-2 twin fin Rick is 12 lbs. #12 is a 6-2 “msf” style eps with 2" wood strips carbon fibered between the eps. the shaped blank weighs 2.5 lbs. i’m gonna vac bag carbon fiber deck.

I’m using 1# eps on the above and gloss coated all but the 5-6 fish.
