Tiny Dancer Mark III is a low-tech version of the Tiny Dancer proa.
Its designed to be owner built in Western Red Cedar or
foam core strip plank, with fiberglass skins.
In order to keep the extreme performance of this personal proa, the decision was made to
accommodate the heavier construction method with a longer waterline. The main hull is
increased from 21 feet to 23 feet, and the fineness ratio was conserved at 21.5:1. The
ama, or windward hull, was shortened in length to 15 feet to conserve weight. Like its sister boat, this is an ultimately simple sailboat. Its all sailboat with
nothing extra.
There are a few choices in the design. There is a narrow version at 8.5 feet, which is
trailerable assembled, and there is a 10.5 foot wide version which must be disassembled to
be transported. The narrow version uses a single rack to windward, and generates the same
amount of righting moment as the wide version. The narrow version takes longer to build,
as you have to construct the rack also. The narrow version is ready to sail when you reach
the water, just plug in the rack, tilt the boat to 60 degrees and plug in the mast.

There are
two rigs for the boat: short and standard rigs.
In either case, both sails are reefable. |
| If you sail in
an area where wind speeds are regularly above 15kts., you might consider the short rig. 
|
|
The proa is optimized for boatspeed in a
range of conditions, from a few knots to 15 kts. for the standard rig. 
|
The short rig
would also be a good choice for a beginning sailor, as the standard rig produces a great
deal of amount of power.
|
| The design package sells for $300US. It includes more than 30 large drawings and
instructions for building. All of the mold stations are plotted out full size. Only a
total of 10 unique mold stations are required. The hulls are symmetrical fore-aft and
therefore a single mold is used to produce both starboard and port halves. The same mold
stations are then re-spaced to build the ama. Typical time to build is 750 hours. |
