Pro Tournament 21
Pro Tournament 21
Pro Tournament 21 - Diamond in the Rough
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.

Proudly Australian Designed
From the first sketch on the drafting board to the finished computer 3D modelling and CAD plans, every boat is designed in house by Mark Bowdidge (MRINA) himself.
After nearly forty years of building and designing boats, every design is specifically designed for Purpose, Performance, Seakeeping and Safety

Pro Tournament 21 Frequently Asked Questions
What is included in the Pro Tournament 21 Plans?
In regards to the Pro Tournament 21 plans, it includes:
- 25 sheets in total (13 x A1 sheet size and 12 x A0 sheet size - full size bulkhead patterns)
- Full size patterns for bulkheads/ stem frame and transom
- Builders manual
- Bill of materials
- Over 300 build photo's for you to preview and assist with your build (A picture tells a thousand words" as the saying goes)
- Tip's and Tricks" e-book for building your boat
- Actual Performance results with various outboards/ props showing speed/ fuel consumption and more
- A link to our PRIVATE "How to strip plank" video
- Plus a lot more
Below is an example of the type of plans you receive
Is the Pro Tournament 21 Builders Plate Compliant? (Australia/ USA/ Canada and the EU)
Yes.
We use the ABYC standard (https://abycinc.org/). (We do not use the AS 1799 standard, as we feel that this standard is full of "holes). Using the ABYC standard, all boats under 20ft MUST meet LEVEL flotation. It also means that the boat must meet certain stability criteria in regards to traverse stability, wind heeling criteria and max Hp allowed.
The Pro Tournament 21, as designed exceeds the requirements for LEVEL flotation compliance. This covers the boat itself/ outboard/ people and cargo.
This standard is accepted worldwide. (Australia/ USA/ Canada and the EU)
We do not design our boats to meet BASIC flotation. To me, "Basic" flotation is dangerous.
Hope this helps
So what does the term "Strip Plank Composite" construction mean?
So… what does "Strip Plank composite" mean?
The term “composite means that if you use 2 or more materials in your construction layup, you must take into account for the mechanical properties of each material used. i.e. with the planking itself and the glass used, we have to take into account for the materials Tensile strength/ Bending strength/ compression strength/ Shear strength and Modulus of Elasticity) in your engineering calculations. With the planking itself, we need to know the "Core Shear Strength" as well. When you do this, its now called a "composite" construction.
Once it passes Tensile strength and bending strength for a particular area, we move to the next section. This method of engineering is applied throughout the whole boat.
Now… simply building a strip plank boat (in the traditional sense) and wetting out some glass on it, is not composite construction. Its just a strip plank boat with glass laid on.
All our Strip plank designs are engineered as composites and in this regard, we engineer out boats to “Class” rules. In other words, we use Commercial ship standards. Here we use ABS or the "American Bureau of Shipping (https://ww2.eagle.org/en.html)
Here’s just one small area within one of our designs (as an example), of the calcs we do with all our designs.
I hope this helps

I can't get Paulownia or WRC for strip planking. What can I use instead?
This is a question I get from time to time.
In this regard, simply send me an email, let me know what local planking timber is available and I'll do a quick number crunch to let you know whether it can be used or not and if so, what planking thickness will now be required.
Too easy
Can I get replace the plywood internal structure with foam core?
No.
By doing so, your:
1/ Making the boat too light. This means the boat will float higher in the water, exposing the chines which in turn results in the moment of inertia of the waterplane being reduced which results in an unstable boat.
2/ Taking the weight out of the bottom of the boat also raises the overall centre of gravity which further adds to an unstable rolly boat. Why? Plywood has a density of approx. 600 kgm^3, whereas foam has a density between 80-240 kg/m^3 (pending foam core used). So in effect, you've taken out between 60% to 87% of the weight that's down low. Whoops. Now you have a serious problem with stability.
3/ The boat will become too "flighty" when on the plane.
BUILD THE BOAT AS PER THE PLANS and you won't have an issue.
Can I build the boat from Foam core?
Definitely not.
See above topic "Can I replace the internal structure with foam core" except now its even worse.
BUILD AS PER THE PLANS
Do you provide CNC cut files or kits?
No I do not.
So please don't ask, as refusal may offend
