for starters :
sheet of plywood (1/4 or 3/8 or 1/2 )
hand saw or skil saw or saber saw or table saw.
cut 145 x 42 rectangle
screw down some straps and go for a ride.
add some fins
go for a ride
use a hand plane to alter rail shape
go for a ride
if it feels too big bring out your saw and cut off the ends
go for a ride.
you get the idea.
if you want some built in rocker or concave:
you can sandwich 2 sheets of 1/4 inch ply using epoxy (or gorilla glue)
prop ends or middle with bricks and clamp to get desired results while glue sets.
not likely you will need glass for your weight but that is your call.
you can use glass to set rocker/concave instead of sandwiching two sheets of plywood
epoxy is good adhesive and good for laminating
its not a good varnish and too expensive compared to a good urethane uv resistant varnish.
so if you decide to glass , do that first and paint/varnish any cosmetics later
things haven't changed that much since these kids were active building kites and boards
it may give you some ideas .

From my experience building skim boards using this method, 3/8s is about the thinnest you can use especially if you are doing any jumping.Have you tried 1/4", any success?
