Broker's Comments

Here is a very well-respected Monk design in the Roughwater 42. Noted for their long water lines which move through the water with great efficiency. This all-fiberglass model shows long standing pride of ownership, and the seller's attention to detail is evident. The twin GM 8.2 engines provide for 10 kn. cruise. This Pilothouse model provides a cockpit, upper deck with an enclosed upper helm, an aft cabin with access to the cockpit, and a transom door. Here is a truly versatile 42' Trawler that is equally suited for long distance travel and as a comfortable live-aboard home.

“ Concerned about moorage? Where can I keep this boat”? Waterline Boats on Lake Union in Seattle will offer at least 3 months transitional moorage (at market rate) for this boat.
