My thanks to Mosquito Boat Hobbies for their semi-kit... saved me weeks of work... probably months. it's a shame Dumas has stopped making their 48 inch hull. I was lucky to score this hull on EBAY. Runs on two max size Astro Flight motors with a 12 volts.

Ahoy
here is a few pictures underway and display of my 1978 issue Lindberg PT-109. I had this old boat for 32 years for power nothing to get excited about. not to much into speed but she goes fast enought not enough to raise the bow out of the water. I didn,t use the kit motor it was to much of a toy its design was primarley used for pool opperation. there for I replaced it with dumas 6 volt electric motor useing the kits reduction gearbox they give you. at the time of the build I had no forsight discard it, perhaps in the near future Iwill scuttle it and use 2 direct 6 volt motors the gear reduction slows down the speed pretty much if you use scale speed it is good for cruiseing at 6 knotts. the gear reduction has been coated with grifite grease as long as I had this old relic there are no wear on the gear teeth so she is good to go untill I decide to scuttle this old gear box. Here are a few attachments of this ols sailor

Fishing cruiser built from kit by Dumas- no longer available I believe. Powered by Graupner Speed 500 on 7.2 volts with MTroniks 15 amp ESC. Travels at brisk walking pace so not exciting, but nice to watch. Has a big boat feel even though only two feet long.
There's a video of Scoter on the water.

Scoter was built from a Dumas kit ordered from America. it is a planked hard-chine boat reperesenting an East Coast fishing cruiser, She is 2 feet long with a Graupner Speed 500 motor running on 7.2 volts through an MTroniks 10A ESC. The crew are from George Turner Models, 1:12 scale resin figures.

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.

This boat is a cabin cruiser. it is powered by 2 dumas 12 volt motors, one motor fried. This boat minus elecs and motors is for sale at 75.00 plus shipping.

Had it in water this year about 1 month ago. This boat you will not find anymore. The plans are included with it.

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.
