I've done it by making a removable secthion that is like a tub if water comes over the stern, and it always does if you go astern the water only goes in to it and not in to the bottom of the hull, it seems to work ok and there are several ways you can do it. this is pre Paint

My Amsterdam is done from an old Latina kit. it has the board on frame hull construction of the older kits. I've done some modifications from the kit such as, larger bridle winch, bridle assemblies, extra aft deck detail, lowered engine room cover, brass lifting boom, recessed anchor pockets, enlarged rudder and various miscelaneous detail changes.

This model is a British "Hunt" Class destroyer.

It is a Sirmar limited edition (100) semI kit at 1/48 scale and some 6 feet in length. When he bought the model it was already constructed, but as a static model. So out came the jigsaw, Manual NOT powered.

The deck around the aft gun turret was cut to allow a good inspection of the inside of the hull. He tried to remove the bridge superstructure but this would have meant destroying it to remove. Out came the jigsaw again and cut an access hatch in the main deck.

The steering servo was fitted and attached ( by keyhole surgery ) and 2 x MFA 800 motors were fitted. Scale Prop Shop Props were fitted and the radio gear just jury rigged for her first trial. She was roughly ballasted with 2 x 12volt 7Ah batteries and she was ready for her first trials.

She sailed well with no water ingress to the hull, so the radio gear was installed properly with individual speed controllers to each motor. The results are as seen here.

This is my ** version of the Sea Queen. My father owns one of the originals and when one lunch time I saw one on the ** web site I knew I had to get one.
It was to be a winter build project and work started in the autumn of 2006 and it was launched in May 2007. I was very disappointed to see the all white paint finish used on the ** advertisements and decided I was going to re-create the look of the original. Cosmetically the big problem was that the original used mahogany finish ply for the cabin sides and the ** version was just plain birch. However after a bit of staining I was quite happy with the finished colour. This was contrasted against clear coated lime wood deck planking.
Also ***a€™s bag of fittings missed out on the signature life belts so I had to make my own.

One Improvement that I did make was the inclusion of a dashboard, instrument panel and throttle slide.

The graphic on the transom was a custom cut from callie-graphics.

The supplied motor was replaced with an MFA Torpedo 850 which is a direct replacement. ( Same mount, same screw fixing centres etc ).
Battery is a 12V 7A gel cell, ESC is an Mtronics Marine Viper 40A

The hull of this model was my own design in 2004 and was sailed for 2 years, and then a new upper decks and battery system were added during the winter of 2005. The hull performed well enough but my original cabin design was too crude to keep.

The boat shown here depicts my effort to copy a 1958 ChrisCraft Cabin Cruiser at a scale of 1" = 1'.

The hull is 1/8" thick pine planks on frames with hand cut Walnut decking and 3/16" Walnut cabin sides. No epoxy or glass was used on the hull - just a good paint job.

The big change was to replace a bulky & heavy 12VDC leac acid battery with 9 AA dry cells connected in series. Bathtub testing indicated I could expect about 2 hours running time at full speed and that estimate was about right. A Dumas 12VDC motor and mechanical speed control were used with a JR XR 2 control.

The reduction in battery weight made a very large speed and appearance difference. Availability of the AA cells was an economic plus.

John called this model "Nancy Dancer". it started of with plans from 'Nexus Plans Service' for Vic Smeed's 'Vivacity'. John used the hull only plans and created everything else himself. it ended up LOA 49" with a beam of 17". With the 12VDC battery the weight came to 23 1/2#.

Because of his basic 'Sedan Cruiser' he designed all the mechanicals and electricals beneath the main cabin floor, including the battery. There was quite a bit of detail put into the main cabin - unfortunately not shown in the photos - including a galley, eating area, furniture and the helmsman's station. The scale is 1" = 1ft.

This hull is plank on frame using 1/8" pine planks. Below the waterline there's epoxy & glass and above there is just epoxy. All the brightwork, cabin housing & decks is natural Cherry with a clear urethane finish.

The power is a Dumas 12VDC motor with a mechanical speed control. The bottom photo shows that he added a 2:1 gearbox to the motor and ran it in reverse to increase the prop RPMs. He also included a constant running fan to cool the motor due to the confinement of the space.

The single propellor is 2" - 2 pitch - 3 bladed bronze. As on all his models he used a 2 channel JR XR2 75 mhz.

Finishing this boat. its a 46 inch and looking to put a 21 size engine, used of course.

I'm still looking for the deck fittings and such for this boat as well.....

This is a model of a sidewall hovercraft fire and rescue boat (Hovermarine HM218) built by James Ramsey.

This started its life as a broken hand vacuum cleaner. Opened up there are two squirrel cage fans. He obtained pictures, sale data, amd small GA drawings from a Hovercraft Museum and was able to scratch build.

It has twin motors operated through mixer and two ESCs, steerable fire monitors plus nav lights, deck lights, flasher, fire pump, siren, rear mast lights and serch lights operated from the transmitter via a Digiserv unit.
