I have listed this boat as a cruiser class for the main class and sportfish as the second class.  I think this boat will make a very good cruiser.  She will be economical to run with her 260 HP engines.  Her flybridge is huge and fully enclosed and her aft deck/cockpit could be used for more than just fishing.  Her accommodations are well executed in fine teak woodwork and she has the storage to head out and do the loop.

 Excerpt from Powerboat Guide

The Mikelson 42 is the boat that put Mikelson in the sportfish business back in 1986. Designed by Tom Fexas, shes a notably handsome flybridge sedan whose profile is accented by a long foredeck and large cabin windows. She rides on a fully cored hull with rounded chines and a shallow keela hull specifically designed for maximum fuel efficiency in the 20-knot range. While several floorplans were offered during her production years, most Mikelson 42s were delivered with a two-stateroom galley-up layout with a single head. A lower helm was standard, and the interior is completely finished with handcrafted teak cabinetry. The cockpit, partially shaded by a bridge overhang, is large enough for two or three anglers to work without being crowded. For a 42-footer, the Mikelsons flybridge is very large. Additional features include a radar arch, wide side decks, transom door, teak cockpit sole, and teak-and-holly floors throughout the interior. Among several engine options, twin 260hp GM 8.2L diesels cruise the Mikelson 42 at 1618 knots and achieve a top speed of around 20 knots.
