A 56' Auxiliary Ketch
Brewer Design #27

With her husky diesel engine, MYSTIC is definitely a motorsailer but she is a seagoing motorsailer, able enough to circumnavigate the globe and fast enough under sail to take 2nd in Class B in the 1969 Trans-Pac race.

Construction is of aluminum to sturdy scantlings, strong enough to earn her Lloyds' 100A class when she was built. Though she carries a low 22% ballast ratio, MYSTIC has deep tanks to add another 3-1/2 tons of fuel and water deep in the keel. That she has ample stability is the fact that she has raced through 40 knot winds under full sail, with the designer aboard, and never had a problem.

MYSTIC's accommodations provide an owner's great cabin aft that can sleep 2-4 and has a private head with shower. Forward is a 4 berth guest cabin forward that can be converted to 2 double cabins, a crew or guest cabin with double berth and another head with shower. The galley is a gourmet chef's delight and this designer has eaten many fabulous meals prepared in it.

The steering station, unprotected on deck abaft the house, may look unusual but it offers grand visibility and is a real delight in good weather, as I know from experience. When things turn foul, then that's the time to head for the pilot house which provides a sheltered watch station and a complete nav area.

MYSTIC's ketch rig moves her along nicely and both spars are keel stepped for maximum strength. When the wind lightens, that large foretriangle can spread a huge spinnaker to keep her moving and, if the wind dies altogether, a husky diesel of 150-200 hp drives her along at hull speed.

Although designed over 40 years ago, MYSTIC has a timeless style with her clipper bow and sweeping sheer and she looks just as pretty today as the day she was launched. Skippers looking for a thoroughbred motorsailer, one with a pedigree, would be wise to look over MYSTIC's plans and see how well she might fit their requirements.
