Yeah I know what you mean, once you are travelling in heavy seas in a go fast you better keep going, else the seas WILL roll right over your back deck. That is part of the reason I installed a removable aluminum box on the stern of my Sonic 30SS. I used to troll from my boat offshore and heavy seas would roll right up the engine hatch to the back seat tops. YIKES! The box solved the problem. Frankly without such a device, it is unsafe to stop an offshore boat in heavy seas....glub glub.
