Waterline

Hi John,

Ordinarily, depending on engines fitted, etc. and when static, the loaded waterline would be horizontal and situated approx. just below where the spray rail is marked, positioned roughly 1/2 way up the hull's 'topside' between the bottom of the collar and the chine, but still as near horizontal. That is when fully loaded, slightly lower of course when light.

As you can see there's an appreciable amount of rocker in the keel line as it progresses forward to a tightly curved forefoot. This was drawn to minimize any tripping effect from forward and avoid any bow steer by not having too deep a stem while at the same time leaving sufficient keel grip for good directional stability. As already mentioned, there's also plenty of reserve bouyancy to come into play when needed.

General thinking is that any force potentially generated needs a counter force to maintain equilibrium. I've used similar set up in hundreds of ribs since the early 80s with no adverse effect. Quite the opposite.

PS. Perhaps I should also have pointed out that all Carsons of 5m up are designed with the collar well clear of the water even when fully loaded as in the attached photo of a special forces 9 metre weighing at around 7 tons with sufficient fuel for 1,000 miles range. This photo gives a good idea of where the waterline lies.

[QUOTE=Pikey Dave;731292]Barry, if you have a demo boat, it has to be called "Dreadnought" it'd be worth buying one just in order to use the name😄 All the best with the project.


Thanks PD. Good name choice.

And we hope to keep the costs considerably below the originals!

Thanks. I hope we'll get to see one in action before too long. Some side by side comparisons should be very interesting!

Sea Trials

First boat out should be on the water before too long so watch this space. And we have the original Carson 900 model as in the photo posted still available together with lots of data on this model to compare with.

Here are some more shots after last week, safe to say that after a solid week of filling and fairing the plug were glad to have the majority of the fairing behind us, we finished the week by getting the plug sealed in readiness for the application of the Durabuild primer and final prep of the plug this coming week.

Following on we will then be laying up the mould and all its external structure as well as building the large standard console/cabin.

Everyone involved is really pleased with progress and how the plug is turning out.

Jwalker next time your in Buckie drop past and we will gladly show you around with tea and tunnocks

Very interesting design, as also good looking. The steps are totally different from the usual ones, not only at keel line. Actually it is kind of difficult from the pictures to understand their shape(at least for me ). In the "ordinary" steps, aft part of each step close to the chine is typically higher up than the previous one. Here it looks like they are more or less on a even line. So is the step created by kind of a warped surface?

The white paint makes it very difficult to see the key features, the Durabuild primer is a dark grey which will hopefully show the hull in its full glory. As you mention the steps on the Interceptors are different to traditional stepped hulls, the hull line is continuous with the steps interrupting in a delta format. You could call it a warped shape, it certainly was a pain getting the materials to contort and bend to the shape! I have attached an image which might help out.
