Marlow's good reputation is deservedly for building boats using state of the art construction techniques, which includes the use of Kevlar, mod. epoxy resin, and high density foam coring, and vacuum bagging/resin infusion. Marlow's are stronger and weigh less than your conventional trawlers. This carries over into the interior with honey comb and structural foam in counters and cabinets. The 70's hull offers Marlow's twin strut keel underbody.  The Velocijet twin struts offer propeller protection and superior sea keeping. The 70 can also sip fuel for extended range cruising or get up and go if you need to out run a storm.

The 70 Command Bridge offers a large salon and galley/dinette areas on the main deck. Her full beam master is spacious and with lots of storage and dual heads. The enclosed flybridge is a great place to run the boat with a large seating area behind the helm. All in all this boat can take you and your family on extended cruising trips in safety and comfort.
