COMPLETE BOAT PLANS & FULL SIZE FRAME PATTERNS
... Delivered by DOWNLOAD to your computer within 24 hours of you placing your order.
The plans have all the information you need to build your own boat... Each plan contains all the construction drawings, everything you need to build your boat.
Plus.... we also have a private subscription based BOAT BUILDING FORUM for you to join if you wish, to assist with your build
You can view & print the drawings in full or in sections. BUILD PHOTOS are included in the plan package. For those that wish to print, the plans are printed on A1 for normal construction drawings and and A0 sheet size for the full size patterns). By using the full size patterns and detailed plan sheets, the parts can be accurately marked and cut out.
We are presently changing our plans from paper format (where they were sent out via the post), to PDF download instead.
So please bear with us as our plans will be unavailable for a short time.
Whether you're into chasing Barra, Mangrove Jack, Red's, Trout or Snook, the Tropic 12 is an ideal small estuary/ river boat. Easy on the pocket and packed with features left only to your imagination, the Tropic 12 maximizes it's space with its open and roomy interior, loads of storage and fishable cockpit space. The heart and soul of the Tropic 12 lies in its modified-V hull. Designed for the tough demands of fishing or family excursions, whether you’re into fishing the estuary's/ tidal flats/ freshwater river backwaters and lakes , the Tropic 12 is perfect for this style of fishing. But the real beauty of the Tropic 12 is its wide beam and shallow draft, enabling you to navigate across these areas chasing Barra/ Jacks/ Flathead and more.
The design itself shows forward seating, but if you’re into casting lures amongst the mangroves and along river banks and wanting a forward casting deck instead, then you can simply convert the forward seating arrangement into one. The design also comes with side decks for those wanting a place to store rods or when trolling the sand flats etc and she also has storage compartments within the seats .
Within the seats there are 2 large sealed lockers, for all those items you may want locked away, while still retaining the foam filled buoyancy compartments in the outer seat sections, as required to comply with the standards.
Overall, it's the perfect, yet simple all rounder that's easy to handle. Designed for ease of construction for the first time builder,
the Tropic 12 is light enough to be easily trailerable for adventures in distant places. But overall, it had to be simple and easy to
build, without spending everything you have.

MATERIALS LIST FOR THE TROPIC 12
The following list of materials is approximate and intended for calculation of approximate costs. We offer no guarantees of accuracy. The list is for all plywood in the construction of the hull, deck and interior. Allowance has been made in the quanties for about 10% wastage. Resin and glass quanties are only approximate.
MARINE BS 1088 OR AB GRADE PLYWOOD
6mm (1/4") - 6 Sheets
9mm (3/8") - 1 Sheet
RESIN AND GLASS (For coatings and reinforced areas)
Epoxy Resin & Hardener - 24 kg (6.34 US gal)
195gm (6oz) cloth - 24 m ( 27 yards)
1 kg (2.2 lbs) glue powder (Cabosil)
1 kg (2.2 lbs) Q-cells (fairing Powder)
The materials list above covers all the supplies for the boat as designed.
Useage of materials may vary due to several factors. For example, a experienced builder will use less resin. Our resin calculations are based on a 50% glass content. Options, customization and variations within your build will also effect the bill of materials and outcome.
Anyone can Build a Boat. Its that Easy
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. A jigsaw and drill are about the only power tools required. The resulting boat is incredibly light weight, strong, and durable.
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.
The stitching is done with plastic electrical ties passed through small holes along seam edges. These are zipped tight to hold the panels together. The glue is then applied between the stitching and also on the inside in a cove-shaped fillet along the seams, along the outside and inside. After curing, the "stitching" is removed and the gaps filled. Then the hull is covered in glassed.
Plans for all our designs include instructions, material layouts, and material listings. In addition, the patterns provided are precise, since they're taken from the actual 3D modeling and CAD systems.
