Refits & Remodels



18’ Marshall, 1968, #8


In 2009, a very loving owner of this early Marshall 18’ decided that he needed to make an adjustment to the original Marshall design in order to expand the size of the cockpit and allow room for more comfortable picnic sailing excursions for his family and friends on Cape Cod Bay. Working with Olsen Marine, a plan was hatched to cut back the cabin and expand the bench seating area and cockpit, all keeping within the beautiful lines and vintage of the original design. Along with the new cockpit, interior, cushions and centerboard trunk, Olsen Marine added fresh varnish and paint, newly polished brass, a new sail and a quarterboard. The result was stunning, a huge success and a toast to the Marshall class. The improved design led to many day and moonlight sails on the bay with room to recline, spread out and enjoy the motion of the Marshall on the ocean. Spring 2012, Olsen Marine will install a custom designed table made to compliment the lines and layout of the cockpit.


1958 26’ MacKenzie Cuttyhunk


This completely remodeled beauty by Olsen Marine is available for sale to a loving owner. Mackenzie Cuttyhunk bass boat is a name synonymous with rugged construction and sea kindly characteristics. A true classic! Olsen Marine has endeavored to give a rebirth to this vintage classic using only the finest of materials and modern construction techniques, coupled with the best traditional boatbuilding skills on the Cape.


We are proud to present the water vessel  “TRUANT” as a legacy to the MacKenzie fleet. Ed Koskella (former founding member of the Mackenzie Bass Boat Club) brought this early 1958 Mackenzie bass boat to our attention a decade ago with hopes that eager minds and hands would restore her. Evidence of her neglect was obvious and hopes of her resurrection were dim. A between boat projects plan to build her anew was hatched by Olsen Marine. Upon her recently replaced keel, new oak frames, copper riveted mahogany planking, and a modern diesel power plant appeared over the course of a few years. Her original bronze hardware restored, fore-n-aft operator’s stations installed, bright finish mahogany windshield and trim work fashioned to the era, and all capped off with a stunning color scheme. She was launched, tested and proved herself tenfold.

Andre Mauric 53'


This Andre Mauric design jet boat of 53’ was built by Story's Shipyard in Essex, MA, in 1996. A customer purchased her in 1998.

New 420 Yanmars, an electrical upgrade, a teak after deck and seating bench, teak and holly cabin soles, and complete exterior paint job were completed as well.
