Hello fellow racers.

We river race and as such hit submerged rocks hard.

Does anyone have any experience with impact resistent Laminates.

We have tried

4" Polystyrene Hull core 9oz Kevlar + 2 Double Bias Glass 11oz + Satin Glass 6oz

4" Polystyrene Hull core + 10mm end grain balsa wood + 3 x 11oz Double Bias Glass

4" Polystyrene Hull core + 4 x 11oz Double Bias + 6oz Satin Glass

Does anyone have any experience and or has done some testing? Any advice would be appreciated.

Think light weight and impact resistant.

Brad
