'Mary D' by John Simons
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.

The "Nancy Dancer" built by John Simons
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.
