'Solar Challenge' June 10th 2023

20 new boats were made for this year

Four challenges: Straight running, guess your run time, racing and concours 

All you had to do was aim your boat

and score points between the buoys

and it was timed to compare to your guess

Andrew's 'Pantene' bottle based boat scoring 1 point for an outer

then knockout racing between guide ropes 

Malcolm's vs Deklyn's brick shaped models

11 of the 15 boats that competed (concours d'elegance judging)

Bill changing propellers for the racing

You can do this too! It takes just a few days to make one of these

A basic shape boat of 205mm by 65mm (the maximum size allowed) made from Liteply

Day 2 fitting the standard 500 size solar motor, 2mm propshaft and a 30mm M2 prop.

temporarily using brass tube for alignment, will be replaced by 1/16 bore silicon tube for coupling

day 3,  add some balsawood sides

...and a liteply top to take the two 60mm x 60mm solar panels

Day 4, a first coat of paint and a home-made rudder

another coat of paint, connect up the wires and away it goes!
