About the TRIANGLE 20
Designer Charles Angle, an early advocate of 'trailer sailing' in the US, had written about his adventures with his own AMPHIBI-CON. The influence here is obvious with the TRIANGLE 20 which appears as a scaled down version of the earlier yacht, and probably a bit easier to tow behind the passenger cars of the day.
