Command Boat 90 - Posted: 13th Mar 2018
Scratch built at 12th scale from pictures and profiles of the internet. The boat was originally built in Sweden a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet

Speed: 40 knots (74 km/h) Draught: 0.8 m (2 ft 7 in) Length: 15.9 m (52 ft) Overall; 14.9 (48')

Complement: 3 (two officers and one engineer); Up to 21 amphibious troops with full equipment Armament: 3 × Browning M2HB machine guns; 1 × Mk 19 grenade launcher; 4 naval mines or 6 depth charges .

The Model
I was attracted to this boat due to its great performance and maneuverability, this was mainly due to the use of twin water jets as the main propulsion, this is a trade off with efficiency.

So my start point was to collect as much information as possible about the boat this involved collecting pictures and profiles of the craft from various sources.

Eventually I found some plans of sort :-

My Dad was a boat builder in the days of wooden yachts, and had showed me how to make plans and frames from a line drawing. I went about this first by creating a prototype about 24 in long out of light ply. I then created full size plans of the model to be made.
Pictures of small prototype finally painted plain green.

The Main model
Used my computer to print out the frames onto paper, cut them out and used them as templates for the ply ribs.

The construction was simple chine style, with 1.5 mm ply.
I tried to build jet drives but failed to produce a effective unit.

So reverted to propshafts which worked out well with better control and the bot can spin on it own axis by putting one engine in reverse the other in forward and adjusting the twin rudders.

That it for now, hope it was of some interest

Hi I like the boat would be interesting with jet drive.
they are available quite cheap for the nqd jet boat from £9.01on ebay item no. 282721477302 comes with cheap brushed motor can be converted to brushless to make things interesting hope this gives you food for thought for maybe future build.
thinking of building a deans marine PBR cannedheat and fitting it with a couple of these jet drives.

I tried one of these but couldn't get it to reverse the boat. Possibly not got the correct set up for the jet nozzle. It pushed a 30 inch fiber glass fast patrol boat very well, might try to sort outlet to give better control. You've raised my interest again thanks, Colin.

Hi Colin to get reverse you need to have reverse bucket fitted controlled by servo drops down over jet to reverse water flow.
hope diagram makes it clearer
