I am looking at sailing in a 50 ft boat from Sydney to Perth. How long does it take and what time of the year is best and worst
Try posting to a forum at this website: www.freodoctor.com.au You should get some of the more experienced owners input.
This is the main WA sailing website - There are quite a few boats that regualrly make the trip back & forth for S2H, as well as cruising / deliveries.
