the design was simply a compromise, to supposedly allow for "simpler" access,and keep one piece door from hitting inwhales..I don't favor the new design,and seems like it won't be as watertight when taking spray on the port bow...my buddy's new twin e-tec 2550 left the factory like that,on the delivery day, he requested the old one piece door be put on for the same reason....you should tell Paul, and maybe get him to ship you the one piece door? There is no advantage of the new design,IMO......
