Pro Tournament 21


For our builders we offer full size printed bulkhead/ frame patterns, printed on 24" wide paper which are taped together to provide fulls size outlines. Using the full size patterns and detailed plan sheets, the parts can be accurately marked and cut out. All Plan sheets are printed on Architectural D (24" x 36" ) paper except for the full size frame patterns.

The Pro Tournament 21.... Diamond in the Rough
          "The ultimate in offshore sport fishing performance"

This offshore power boat design, powered by a single outboard, the Pro Tournament 21 is untouchable in the open water, and yet the 21 will really prove itself when conditions deteriorate. With a standard 200 litre fuel tank capacity, 25 degree deadrise at midship and flared bows, the Pro Tournament 21 will get you there faster, drier, and smoother than the rest.

To put it simply...a Diamond in the Rough !

Other features also include a livewell, toilet facilites, enormous total fish box capacity, walk through transom, recessed grab rails and a huge cockpit area for where all the action is on your offshore fishing rampages.

Loaded to 1400kg (3085 lbs), a single 150 -175 HP will push the Pro Tournament 21 to approx 40+ kts pending load, choice of motor, gearbox ratio and prop selection. As with all our designs, seaworthiness and comfort (smooth ride) is our main priority, not speed. The speeds listed above are approximate and not guaranteed. They are based on the designed displacement and may vary if displacement (or weight) varies.

All speeds assume well-faired hulls driving through properly sized propellers with suitable gear box ratios to match the power and torque curves of the engine, to the hull weight in question.

So regardless of what you have in mind, the Pro Tournament 21  aggressive, yet easily trailered offshore design, will give you endless opportunities to dominate the offshore fishing scene.

Pro Tournament 21
Is it possible to have a cuddy cab with this hull design?

This is a question that is so often asked and the answer is No.

The Pro Tournament 21 was designed specifically as a centre console. With each design, right at the very beginning we have a specific purpose in mind and then design the boat to meet that criteria. In the case of the PT21, it  was designed to be a hardcore, offshore fishing boat, long, lean, mean and light. As a part of the design spiral, the Pro Tournament series had to meet specific requirements: Performance/ seakeeping/ stability/ a deep deadrise for wild offshore conditions, a "mattress" ride...the list goes on and on.

By adding a cabin, everything changes and the Pro Tournament 26 wouldn't meet the criteria that we designed it for.

The following list of materials is approximate and intended for calculation of approximte 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.

CHIPBOARD OR MDF (For the temporary frames)
8x4ft sheets (2.44 x 1.22m) 19mm (3/4") - 13 Sheets

30mm x 12mm - 27 sq.metres/  (1-3/16 “ x 1/2 “ - 291 sq.ft)

MARINE BS 1088 OR AB GRADE PLYWOOD (Density no less than 600 kg/m^3 or 37.5 lbs/ft^3)
9mm (3/8") - 4 Sheets
19mm (3/4”) – 13 sheets

RESIN AND GLASS (For coatings and reinforced areas)
Epoxy Resin & Hardener - 200 kg (53 US gal)
400-450gm (12oz) Double Bias (not Biaxial) - 200 m ( 218 yards) - Buy 2 rolls
10 kg (4.4 lbs) glue powder (Cabosil) (Cheaper to buy a 10 kg box than by the kg)
10kg (6.6 lbs) Q-cells (fairing Powder) (Cheaper to buy a 10 kg box, than by the kg)

The materials list above covers all the supplies for the boat as designed.
Useage of materials may vary due to several factors. For example, experienced builders 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 laying the planks onto the temporary frames, allowing the planks to "find their own way" from bow to stern. We also use tile spacers to provide the gaps between the planks to push the glue through at a later stage. Once the planks are fixed into position, we can then begin gluing the planking into place. By doing things this way, we're not under pressure to plank up fast due to the glue going off, but working at our own pace. It also means that the planks themselves are not tortured into position, using clamps or whatever to hold down, but the planks "naturally" want to lay down as they ar laying naturally of finding their own path. Its that easy. (see video below)

Once the planks have been glued, its time to give teh hull a quick fair with your sander, then time to begin glassing.

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.
