Changed from the single rudder to twin rudders (came up with a solution without going shopping) and have better steering now (probably too good😀) might need to reduce movement in the TX set-up. Will behave differently on the water as in the vid it's on a 30deg slope making it hard to steer, plus the slippery plastic strapped to the hull. Does good donuts though!😁

Zoom 1 (Interceptor) Mono boat.
Built from a Glassfibre hull, brought on Ebay for £35 the hull is a slim mono racing type with a self-righting side cabin it runs a 1400W 14V 2958 4200KV Brushless Motor and 29-S Water Cooling Jacket with additional air cooling fan.
I did not want to use a flexi drive as high maintenance and prone to failure so the shaft runs via two universal joint one at each end. the propeller is a 38mm copper alloy
The ESC is a 200W and water cooled the twin rudders supply separate water one for the motor and one for the ESC.
The rudder are positioned to reduce prop-walk and are hinged to prevent damage if you hit a object in the water and also for ride adjustment.

Turn fins and trim tabs for ride adjustment were provided by a spares kit for another boat. also foamed and added an inner sealed hatch, a rubber bump strip and safety loop.

An old favourite from my hovercraft phase. Runs really well on land and especially water. Although no reverse, it will auto-rotate on the hover, so when pointing in the desired direction on with the propulsion with the brushless motor and away she flies.
Realistic in operation. Looking a bit work worn now. Could do with up-dating with Lipo batteries which would make it even lighter. Seen here with lift motor running with skirt inflated. Steering
interesting, with twin air rudders. Must get some videos of the action.

a 30"scratch built pt. boat, I built hull from .8mm ply using a resized eezebilt 20" plan.
the deck fittings were copied as best as I could from photos and drawings found on line. powered by 2- 2200kv brushless out runner motors through 2 20 amp speed controllers. twin contra rotating props twin rudders fast and light a pleasure to build

Decided to sail the Solent so took some video to share. Uses 2 Bhuler 12v brushed motors with 4 bladed 45mm PropShop props and 12v 12AHr SLA. Twin Electronize ESCs. Radio is Futaba 6Ex but I will probably change to the Taranis so I can get better control using some bespoke Tx settings to co-ordinate the props and rudder.
Lifeboat crewe had been on a night out so not quite vertical. Aplogies for the shaky video, it's difficult to sail and video at the same time.

I built this vessel from scratch using a pre made clinker fibreglass hull purchased from Mini Steam Australia. The engine is an oscillating twin cylinder and the boiler is a 3" Centre Flue Gas Fired Vertical Boiler from "Miniature Steam". The gas tank is a 1-1/2" vertical refillable GasTank also from Miniature Steam Pty. Australia. The vessel is radio controlled with the skipper appearing to control the rudder. it has a smoke generator and a rc controlled steam whistle.

My 1st excursion into model boat building about a year ago....steep learning curve!!!

Currently powered by 2 x 480 brushed on 11.1v, both motors independently controlled by 2 ESC but soon to be refitted with 2x 1000KV brushless.

Planes beautifully and with twin rudders turns on a sixpence!

Wahine was a car passenger ferry of the Union Steamship Co. of New Zealand, and completed by Fairfields in 1966. She was lost in a major storm in the Cook Strait in 1968 with the death of 53 people. The model is substantially scratch-built with some fittings purchased. it is driven by two Graupner Speed 500 motors powered from two 6.6V 3200mAh LiFe batteries. it is fitted with twin stern and a single bow rudders, and bow and stern thrusters as on the original. The smoke effect is provided by a Steam Master Unit.

This 1/12 scale model is based on the Aerokits Solent Class lifeboat. Over the past 5 months it has been under going a major refit. I originally built the boat about 35 years ago and got the "bug" again last September. I've done the best I can to make a silk purse out of a sows ear.

Its powered by two MFA Torpedo 800 electric motors. power comes from two lead acid batteries, each rated at 12v 7Ah. Control is provided by two Mtroniks Tio ESC. The twin spade rudders are linked to one servo. Each ESC has its own receiver. I found that one receiver, using a Y lead, could not continuesly keep the two ESC supplied with a signal and they kept going into Failsafe mode alternately. I got round it by binding two receivers to the one transmitter. Within the engine compartment is an automatic bilge pump. Two probes detect if/when the water level rises to a certain amount in the bilge and activates the pump.

The model has working radar scanner , navigation lights, search light and blue flashing light.

Presedent Perkasa Fibreglass hull
moving along nicely all running gear installed 2 x 1400kv EDF Motors with 2 x 90amp watercooled esc,s running on 2 x 11.1v 5000mah or 2 x 14.8v 5000mah twin rudders 45mm X props if it runs anything like my other one I will be happy still lots of finishing touches to be done

YET ANOTHER FERRY BOAT.
THE MODEL WAS BUILT BY MYSELF IN 2008 ON A FIBREGLASS HULL FOR WHICH I AM PART OWNER OF THE MOULD. THE REST OF THE MODEL IS BUILT FROM LITEPLY AND PLASTICARD. BEING WIDE BEAM AND SHALLOW DRAUGHT THESE MODELS SAIL WELL AND REQUIRE NO BALLAST APART FROM THE JELLY BATTERY.
IT IS TWIN SCREW AND TWIN RUDDER SO IS VERY MANOUVERABLE.

This was scratch built apart from the fibre glass hull which I purchased.
Model is 65" long with a beam of 10". Power is by electric running via a gearbox at 300 rpm. Ihave taken almost 2years to complete the model working most days on it. Attention to detail was the order of the day.
I am using a Planet T5 Tx and Rx, 5 channels. I have a smoke generator pushing steam out of the twin funnels,synchronised to forward speed, faster the revs, faster the steam. Conventional rudder operation.
Have an operating Radar, ships horn, simulated steam noise varies as speed is altered, full navigation lights,all cabin lights can be switched on and to keep the 106 passengers happy I have a Banjo Band playing to complete the scene. Have sailed it recently at Peterborough and performs really really well. Have to say it tends to attract a lot of interest.
I am now constructing the Ayton Cross tug in 1:32 scale, with all the detail I want.Plan is to tow the Jeanie Deans around when completed as well assailing her
