You know what happens when you start throwing spanners about..............usually one or more end up in the machinery and it takes someone bigger than Tarzan to pull them out.

To answer your points one by one:

The motors wont fit without the countershaft unless I change the angle of the propshaft by increasing it beyond 8deg incidentally this would also raise the motors within the hull and compromise the centre of gravity,

Brutus has the same design profile as the full size ship, it looks blunt simply because its a speed boat as opposed to the super cruiser in your photos.

Theoretically the hull shape should work without having to fit trim tabs or elevators, notwithstanding the fact that their very presence would change the hydrodynamics of the hull and create more problems than they would solve....they look awful and would ruin the lines of the design.

Spanners are for tweaking nuts.

Tarzan hey!......AAAAAAAAAAaaaaaaaaooooooooooOOOOOOOOOOOAAAAAaaaaaaaa!!!!!!

Those were the days, hey!

I did say earlier.....Why not increase the prop shaft length and get rid of the belt drives?

The hull shape at the front doesn`t look sharp enough?

More to follow

Good Morning Captain Bob

Unfortunately increasing the tube length would have to go hand in hand with raising the height of the motors within the hull and this will change the centre of gravity making the forward section of the model unstable when making high speed turns.

This plan view shows the overall shape of the model

You can see that the prow is quite sharp and that the shape is further enhanced by the curve starting amidships.

For some reason, I imagined a shape like a slice of cheese.....On edge.......Axe Head

You are the designer........Carry on regardless

To get you started the minimum size for the Brutus building board is 1230mm x 380mm.

Building board size.......No problem

Ready when you are, Govner!, but will have to take second place to SloMoCruiser for the time being

Just had a right picnic with my password....OK now

What a shame the top view does not look as futuristic as the side view!!

Bob, it needs some "ray gun" exhausts and rocket fins, or something devil when you start.....

I suppose the outlandish deck line will give it the desired quirky look?

Plus a couple of stubby wing things.....I also like the shark type trim tabs down below

Make your own contribution to the Website

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
