I don’t know much about the Mainship the Carver is nice boat have a friend that has one but is gas powered so does not perform that great. We have the 420AC and me and my wife can handle it very well just me and her. Last year put 350 Hrs. on it up[ and down the gulf coast and the 3116 cats do just fine a lot of people don’t like them but frank on this site will tell you treat them right and will get great service out of them . We cruise at 22-23 MPH 2400 RPM 24-26 Gal Hr. The 420 AC Has more room that any boat in is class sea handling good Yes has cored hull a lot of sea rays did and just get hull checked and should not be a problem. I don’t know the price on a good used one but think there a 420ac 2001 with 480 cum in Slidell for sale for 220k. Maybe some other will let you know how there’s http://www.boatpoint.com.au/reviews/2001/sports-cruiser/sea-ray/sea-ray-420-aft-cabin-9227
