Trim angle - my verbage for running trim angle, nothing to do with trim tabs up or down. As you stated, in your natural condition without trim tabs it runs bow up, needs some tab to bring it down to the 3-4 degrees optimum trim angle. If it did not have that min 3 - 4 degrees running trim angle, you would feel like you were plowing. You have a lot of tank management to keep your 58 in balance, a natural part of ownership for most, a pain in the rear for others. Inherent attributes for a flush deck MY with a forward engine room , harder to manage in a frp boat, assuming the tanks are not integral, than an aluminum MY of the same design with integral tanks, just the nature of the beast. Most owners today don’t want that kind of fuel , water and / or waste tank management, maybe contributed to the lack of new builds for that design? What size/model Mikelson rubbed you the wrong way?
