'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.
