I have owned a 23 and 2-20's. I put spray rails on one of my 20MA thinking they were going to help. They helped with the spray put did not let me take full advantage of the trim tabs and in a sea with some chop they would not let the bow dig down as far and kinda made the boat ride alittle funny. Basically it did not ride as well.
So I decided I would rather have a better ride and get wet, then not get wet and not have as good of a ride. Curtains are a must on boats!!!
These Seacrafts are very seaworthy. Had mine out 60 miles this past weekend and caught 6 wahoos, 21 dolphins, 3 blackfins, 30 triggers, 20 beeliners. And only used 40 gallons of gas
Thinking of restoring another 23 soon and I will not put rails on mine.
If anyone is interested in some spray rails I will give them a good deal. They are plastic ones about 10ft long/each.
