you're looking at but my Bud <iles cedar Barnegat weighed 120 lbs CRATED FOR SHIPMENT...and that included the oars, the spray shield, the floor boards and the (2) hatch covers....
Since "a little over a 100 lbs" is "a little over a 100 lbs" regardless of the material I don't see the singularity of your particular "a little over a 100 lbs"...
I've seen pictures of the boat you have...neat boat, sweet looking on the water and a flat out "raped ape" at top end....run that boat where I run my barnegat and you'll be thumbing for a ride while you stand in your swamped boat....
Your boat I'm sure has application in some waters. Personally I'll take less speed for the increased ability to handle rough water of the more traditional Barnegat any day....
