Not the answer you wanted but as a former naval architect and owner of a + 500 series N33, I think it is a bit of a lost cause. As an evolved design based on a Baltic fishing boat hull, the design does not lend itself to a spray hood but does benefit from the interior steering position albeit not a great view when bouncing around. Personally I find the high aft deck not the safest place to be in a chop and while we all prefer to be outside, this great boat cannot satisfy every requirement. If you find a solution I would be glad to hear about it. Right now here on the Med I am trying to sort out a Bimini which is not easy on a boat with a low mizzen boom and canoe stern! I have wide (deep ?) mizzen cover with snap fasteners to which I will try to attach triangular side pieces and spread it out like wings. Watch this space! Cheers, Ned N33 521.
