Thanks,
prior to designing the Duma i had a chat with the top Viper sailors in the UK and asked if you could improve the Viper what would it be? And more volume in the Bow was the only real request. I took that and added it to my personal key design features of wanting a aggressively high beam placement and high displacement flat bottom to help carry the weight of heavier crew weights like myself. the high beam placement is to prevent beams crashing in to small sharp chop, something i experienced when sailing a spitfire and found really frustrating. So these key features cumilate to a boat with a lot more volume and hull area, the drawback is more carbon and more weight.
