20 Defiant

About the 20 Defiant

“I have had this boat offshore 30 – 35 miles tuna fishing and it is unparalleled. It rides better than boats 5′ larger and takes confused seas with no problem. I often find boats trail me through inlets because the Maritime cuts the seas so well.” – Current 20 Defiant Owner

20 Defiant: An Offshore Champion

The 20 Defiant is one of our most popular models, large, strong and stable enough to handle offshore conditions in reasonable weather yet perfect for fishing and exploring the shallower areas of the bay with its 12” draft. Owners are impressed with the nimble responsive feel of the 20 Defiant as well as the large area under the console that easily accommodates a porta potti.

The large interior cockpit provides an unusual amount of space for a 20’ boat, plenty of room for friends and family to join you fishing or just enjoy the ride. The wide wrap-around deck allows multiple flush mounted rod holders to be installed, provides protection for the under gunwale mounted rod racks and comes standard with a large rugged stainless steel bow bitt and 6” center line chock.

Functional Console

The 42” console features a 316 stainless steel wrap around rail, rugged windshield and lockable bi-fold console door. Beneath the console there is a step down area that provides 50” of headroom, providing excellent storage space and allowing one to comfortably use an optional porta potti. The 34” leaning post allows one to drive the boat safely while standing or sitting and can be outfitted with a stainless steel footrest, flush mount rod holders, upholstered backrest, and lockable tackle station. Serious fisherman will want to install the 34” Leaning Post with Livewell option, complete with a 32 gallon Kodiak livewell neatly housed in the stylish body of the leaning post.


While options and accessories can be added to personalize a boat to suit your needs, the most important aspect of any boat is the ride and performance, something the 20 Defiant impressively delivers with strength, safety and simplicity.

The 20 Defiant can be powered with a wide range of engines from 70 to 150 HP. It will reach speeds close to 30 MPH with a 70 HP engine and 40-45 MPH with a 150 HP motor.


All Maritime models feature 100% composite construction with a solid fiberglass grid system, ethanol friendly polyethylene fuel tanks, a foam filled floor that creates “unsinkability” and a vacuum infused aggressive non-skid deck. The wide body, rounded bow, external keel and hard chines delivery a comfortable and dry ride, noticed and envied by others during rough conditions.
