The previous owners of Ramona sailed her to Lord Howe in 3 of the Pittwater to Lord Howe races in the 1990's. Racing with a full crew is not quite the same of course. Checked the webpage but there are no times and just a couple of photos, then digital cameras were not too flash either!
Ramona is up on the slips at the moment, coming off in a couple of hours. Talking to one of the fishing boat owners who came past yesterday and he reported a patch of warm water just NE of here. 20 degrees C, still green but with 2.1 knots of current down. In close it's still a green 16c. The conditions are very changeable at the moment.

oceancurrent.imos.org.au/My passage plan would be sail Easterly and make the distance as short as possible with the prevailing winds and current! Clearing the coast as fast as possible.
