THE BROADWATER 5.1

The Broadwater 5.1 design is a very simple and approachable powerboat design, capable of being the perfect companion to adventures on the water.
Originally designed for bay and open water use, I think she would fit in just about anywhere. The Broadwater 5.1 requirements were simple, she had to be a fast and
responsive cabin boat that would allow comfortable cruising whilst out and about, whether it be fishing or simply a family's day outing out on the water.
With a large forward cabin of over 1.52m (5ft) in length, with wide cabin seating throughout to stretch out and relax, large storage lockers, loads of headroom and room to fit a toilet.

The Broadwater 5.1 has a large helm station for a boat of this size, providing ample room for all those favorite electronic toys and also an area of the boat that
provides excellent visibility, control and shelter. With large storage lockers within the helm station for all those personal valuable items that one carries when out and about,
the helm station within the Broadwater 5.1 is designed for easy reaching and putting you in control.

Behind the helm station, the Broadwater 5.1 with a large cockpit and wide side decks for rod holders and grab rails, she also has side pockets and large lockers aft with
a ton of space in the rear lockers for a flush mounted live bait well, bait board, batteries and more.

BROADWATER 5.1 FEATURES

 BROADWATER 5.1 FEATURES

Just some of the features the Broadwater 5.1 includes:

  • Sleek yet simple and functional lines
  • Moderate V hull design for bays/ offshore and fishing the estuaries.
  • Forward cabin with loads of headroom within
  • Side pockets for all your gear plus more
  • Large forward deck  for anchors and even room for a trolling motor.
  • Large 70 - 100 litre underfloor fuel tank
  • Large storage compartments beneath the deck for storage of gear plus a large kill tank when fishing
  • LEVEL flotation for compliance (we comply to the ABYC standards)
  • Engineered to "Class" or Commercial shipping standards for those offroad or offshore fishing adventures.
  • Easily handled by 1 person when trailering
  • see more below...

It also has a walk-thru transom arrangement leading to a large rear deck for swimming or simply climbing on and off the boat. If you decide to keep her on a mooring,
the cockpit deck is self-bailing with the sole being approx 3 inches above the loaded waterline. Also there is 685mm (27 inches) of height from the cockpit sole to the top of
the side decks, which means you'll have heaps of support to lean against when grappling that big snapper or even more important, keeping the kids aboard.

The hull design concept involves a fine entry, long flat buttocks, a variable deadrise throughout and a deadrise at the transom of 15 degrees. This in combination with her chine flats
and running strakes to produce lift and reducing drag, prevents squatting and provides a smooth ride as she slices thru the waves.
So with this in mind, we recommend a minimum Horse Power of 90 horsepower, but keep in mind this hull does not need a lot of horsepower to be driven economically at a good speed over the water.

Under the sole, she also has a 100-120 litre fuel tank, giving you the capability, time and flexibility to do more boating, fishing and having a lot of family fun on the water,
With a 115 Hp outboard hung of the back, the power to weight ratio of the Broadwater 5.1 will deliver outstanding range too, meaning you can cruise further and faster with better fuel economy.
This maximizes your time aboard - providing more options for any given trip, the ability to go and more money in your pocket, not to mention the pride that comes from building your own boat.

  BROADWATER 5.1 CONSTRUCTION

BROADWATER 5.1 CONSTRUCTION

Just about anybody can build a boat using the Bowdidge Marine Design Plywood Composite system. This method eliminates many members that ordinarily require fitting, fairing, and beveling. Thus, it's ideal for beginners. This quick and easy boatbuilding method consists of plywood planking panels cut to shape from patterns in the plans which are "stitched and glued" together at the seams. Such a boat can be assembled in a matter of hours after cutting out the parts.

Build method in summary:

  • Build the strongback
  • Cut hull parts and assemble onto the strongback
  • Glue together and then glass the hull
  • bog, fair ready for painting
  • Roll hull over
  • Glass the interior
  • Fit fuel tank 
  • Install buoyancy foam for compliance to meet LEVEL flotation
  • Fit and glass the sole down
  • Build cabin walls
  • Build cabin interior (seating etc)
  • Build cabin roof
  • Install side decks and other optional fittings
  • Paint the hull
  • Launch day
