Grady White 228WA Seafarer with Yahama 225HP 4-stroke

Hi guys, I am looking at buying a GW and welcome comments from people with experiences with this particular model. I live in Perth, W.Australia and it is regarded to be one of the windiest cities. My fishing spots are about 75kms(47miles) offshore and it is the norm to have 2 metre followings seas on the return trips. I am moving away from a stern drive boat as there is too much space incursion on the cockpit space. My current boat is a Trophy 2052WA DTI engine and would like to hear the opinions of the difference between the 2 boats.
