The patent-pending Montauk-T-Topless-2™ (MT2™) folding T-Top for Boston Whaler® center console boats combines the fishability, convenience and storage of a T-Top with the ability to lower the top in seconds (or remove in 10 minutes) to store the boat in your garage, shed, short dry stack, boat house or under a boat cover.

The new Montauk-T-Topless-2™ (MT2™) has been completely redesigned for 2020, combining the best features of the original Montauk-T-Topless-1™ and Montauk-Shadow™ folding T-Tops (at a lower cost) to fit most Boston Whaler® Montauk™, Outrage™, Dauntless™, Newport™ and Striper™ center console boats.

  • Folds down below front bow rail height in less than 1 minute by pulling (2) quick-release pins to fit in garage or under standard boat cover,
  • 6'2" of headroom (on Montauk-17),

  • Optional 3-sided Spray-Shield enclosure with side 'weather flaps' out to the gunwales (removable with Velcro« and bungi balls),
  • Optional white Navigation Light and Rod Holders,
  • 100% Made-in-USA,

Montauk-Shadow™ Features Movie

Storage at home can save you $2,000-$6,000 per year in storage fees = $10,000 to $72,000 savings over an average 10 year ownership,

Optional clamp-on Navigation Light provides reliable, glare-free light for trouble-free evening cruises.

Optional clamp-on Rod Holders (2 or 4) get your rods up out of the way, and can be used for trolling, while our popular Gear Loft stows 4 to 6 life preservers, freeing up your console for storage of dry gear!

Compare the Montauk-T-Topless-2™ (MT2™) to other alternatives:
  • The Montauk-T-Topless-2™ (MT2™) mounts on the Montauk™, Dauntless™, Outrage™, Newport™ or Striper™ 7/8" windshield grab bars in about 1-1/2 hours, and folds forward to cradle between the front bow rails, where they fit under a standard Whaler® boat cover! The top is out of the way for fishing, solid and durable. The 1" diameter polished stainless tubing compliments the looks of the Whaler®'s rail systems, weighs just 32lbs (Montauk-T-Topless-2™ (MT2™)), and is available in Back or Captain Navy (OEM Whaler color) Sunbrella® fabric In addition, the tops pays for itself in 6 months compared to storage.
  • The Montauk and Outrage used the same console from 1973 to 1990, so Outrage owners will see the same fit as shown on the Montauks pictured here.
  • The Montauk-Shadow fits the Montauk-150 very well, providing 6'3" of clearance.
  • Bimini Tops are difficult to fish around and make entry/exit difficult because they mount on the Montauk at or near the opening between the front/rear side rails. Boston Whaler® charges $1,091 now $1,200 ! for their original Mills® "Sun top (bimini) with boot (black or blue) and stainless steel fittings"
  • Fixed T-Tops must be screwed to the floor with wood screws on Whalers®. They cannot be through-bolted to the back of the fiberglass because Whalers® are foam-filled for flotation. Thus, the wood screws will eventually pull out. In addition, a fixed T-Top wastes floorspace with the mounts, and will not fold down to put the boat in a garage or under a standard boat cover
  • Boston Whaler® introduced the new generation 2002-2007 Montauk-170 and 2002-2007 Dauntless-160 boats with the same low console (p/n 22-J871-00) and grab rails, so our tops only provide 5'11" (Montauk-T-Topless™) or 6'1" (Montauk-Shadow™) of headroom, and the cooler must be removed to lower the top fully. In 2008, Boston Whaler® came out with a new 4" taller console, giving the 2008-2012 Montauk-170 a clearance of 6'3" with the Montauk-T-Topless™ and 6'5" with the Montauk-Shadow™!
  • The Montauk 190 and Dauntless 15 use the standard, Medium-width T-Topless.

Once again, note how the design allows use of the front rod holders.

The Montauk-T-Topless-2™ (MT2™) provides provides significantly more head room than the standard Boston Whaler® original Mills® (pre 1996) or Great Lakes® (1996+, we sell these as well) bimini top's 5'10" height. It allows use of the front, console-mounted rod holders, as well as the 2 rod holders in the Montauk's® Teak Reversible Pilot Seat (RPS, flip back seat). The top folds down and clears the standard 86-quart (pre-1990) and larger 96-quart (1990+) Igloo® coolers (with the cushion in place), as well as between the front bow rails allowing use of a standard boat cover..

Montauk-T-Topless™ Canvas Coverage Image

The Montauk-T-Topless-2™ (MT2™) 20.4 square feet of coverage, yet weighs only 34 pounds.

Montauk-T-Toples™ and Montauk-Shadow™ Mount with No Wood Screws Picture Montauk-T-Toples™ and Montauk-Shadow™ Mount with Split Jaw Slides Picture
Installs in About an Hour

The Montauk-T-Topless-2™ (MT2™) installs on the Montauk™'s (or Dauntless'™;) windshield grab bars using two pairs of stainless steel split rail clamps in less than an hour without drilling holes in the floor or console of your boat and then trying to get wood screws to hold.

All other after-market T-Tops mount to the floor, which is not level on the Montauk®. Since Whalers® are foam filed, it is not possible to through-bolt through the floor, so after-market, floor-mounted T-Tops are mounted with wood screws, which pull loose over time.

The Montauk-T-Topless-2™ Spray-Shield has 30-gauge clear Vinyl windows (also known as Eisenglass or Isinglass) framed with Sunbrella® (any color) and attaches to the T-Topless™ frame tightly with Velcro® (note how it Velcros around the frame inside) and Bungee ball ties. The Spray-Shield wraps around the sides of the Montauk-T-Topless™ frame to keep spray out and has a "smiley" window with plastic zippers which can be rolled up to let the breeze in and for trailering.

The Spray-Shield is split at the bottom and joined with Velcro™ to go around the Montauk's front "Shepherd's Rail", providing a spray-tight, clear window all the way down to the bottom of the Montauk's plexiglass windshield.

The Montauk-T-Topless-2™ will fold down with the Spray-Shield in place (may need to be loosened at bottom).
