The Humphreys designed Half Tonner Potamos

Potamos is a Roller Coaster – derivative designed for D.S.Hart and built in Christchurch, New Zealand. Mr. Hart’s son, Rick, had sailed with Humphreys on Zephyros and had relayed favourable messages back to New Zealand. The Roller Coaster line was considered more appealing for the use intended of the boat than Humphreys’ Glafki/Scorpio line.

We do not have any results documented save for the knowledge that she won Class II of her season’s points series in 1984.
