About the HERMANN CAT

Originally available with Marconi rig option. Molds later purchased by Cape Cod Shipbuilding and renamed Cape Cod Cat

Sailpages Buyer's Take

The Hermann Cat is a rare 17.0 ft gaff-rigged catamaran designed by Charles Wittholz and built by Ted Hermann's Boat House in 1971. With a displacement of 2800.0 lb and a build count of ?, it represents a unique, low-volume entry in the early American catamaran market.

Best for:
This boat is best suited for coastal cruising and recreational sailing in protected waters, appealing to enthusiasts of traditional gaff rigs and lightweight, trailerable multihulls.
Bluewater capability:
With a low displacement of 2800.0 lb and a capsize ratio of 2.25, the Hermann Cat is not designed for offshore bluewater passage-making and is best restricted to coastal and inland waters.
Comparables:
Comparable boats include other early 1970s trailerable catamarans such as the Microcat or early Hobie Cat models, sharing similar dimensions and roles as lightweight, easy-to-handle coastal cruisers.
