My "model" shows me that I need to know now how close/far from the rear of the coaming the back of the seat rest has to be. If you build your own, can you put it as far back as you can as long as your back isn't hitting the rear of the coaming? Or is more room required here to practically make the seat comfortable in long use. Also is there a minumum space required for the spray skirt to have to be at least a certain size to the rear too (makes sense, but I don't know). And is it a good idea to figure the seat being as low as possible. Any information on spacing the seat properly within the cockpit ring is very welcome, thanks.
