Sundowner

Designed by John Welsford

An ocean-going cruiser of 21 ft 4 in on deck, drawn for a customer who wanted to build his own boat and then sail it to Hawaii, Cape Horn and Fremantle. Heavy for her length at 2800 kg rigged with 730 kg of ballast, 9 ft 3 in of beam, 383 sq ft of working sail, 6 ft 2 in of headroom and a small inboard diesel.
