8ft x 28" x 3 3/4" full length concave that starts narrow through the double hull entry and flairs to full width in the middle. Then it tapers out between the fins , but has a chine that flows off each side through the fins. This is a blow up of the recent Hydro Simmons I have built in wood and in foam and glass.
Flat out through the middle , but a chine down each side through the fins.
Looking forward to this one hitting the water
