In regards to the Cruise Control 5.2 plans, it includes:

• 32 sheets in total (21 x A1 sheet size and 11 x A0 sheet size - full size bulkhead patterns)
• Full size patterns for bulkheads/ stem frame and transom
• Builders manual
• Bill of materials
• Over 150 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

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 Cruise Control 5.2, 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 "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

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

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.

Definitely not.

See above topic "Can I replace the internal structure with foam core" except now its even worse.

BUILD AS PER THE PLANS

No I do not.
So please don't ask, as refusal may offend
