                | Noon Position: 38 53.4 S   145 37.5 E Course: N   Speed: 4 knots Wind: NW, F4   Sea: slight   Swell: negligible Weather: mostly sunny, cool Days run: 107 nm sailed (and motored), 88 nm made good  We got around Wilsons Promontory a little before midnight. For most of the 
afternoon we had to rely on the BRM due to the lack of wind. I chastised myself 
at the wanton burning of fossil fuel but consoled myself with the thought of 
watching a large motor cruiser while I waited to top up at D’Albora Marina back 
in Sydney. I loitered off, waiting and waiting. When I eventually got alongside 
and looked at the bowser I saw that they had put in 1000 litres of diesel. By 
comparison, Sylph’s occasional periods of motoring at relatively low 
revs must emit a tiny amount of CO2. (I believe my rationalisation is known as a 
‘tu quoque’ fallacy, or, more colloquially, a ‘you too’ fallacy –the basis of 
Hardin’s ‘Tragedy of the Commons’.) Unfortunately I haven’t seen any biodiesel 
at the fuel docks yet, not that biofuels aren’t without their problems. Anyway … we got around Wilsons Promontory a little before midnight. Having 
not seen a single merchant ship all afternoon, one turns up to pass through the 
traffic separation scheme (TSS) off the promontory just as the wind has picked 
up and I have turned the motor off and started sailing. The ‘Rules’ require 
sailing vessels to avoid impeding the safe passage of a motor vessel using a 
TSS. I had been sailing nicely along the inshore edge of the TSS when, just as 
this large merchantman starts to enter the westbound lane, the wind shifts 
heading Sylph and pushing her out into the ship’s path. Bother! We tack 
to the north back towards the rocky promontory, a vague black mass ahead, but we 
fall into its wind shadow and end up going backwards. Double bother! On with the 
noisy GHG machine yet again. So, we eventually clear the promontory and the merchantman passes safely. 
Now the breeze returns and we can sail once more. Hurrah! I am pleasantly 
surprised to find the wind has backed into the SW meaning we can lay our course 
for Port Phillip on a close reach. Double hurrah! But the favourable shift only 
lasts for a few hours and at 0438 I find Sylph heading north towards Cape 
Liptrap, the breeze having veered back into the west. I put a reef in the main 
to the freshening headwind and at 0530 we tack to the WSW to clear the 
coast. At 0915 we tacked back. The wind is forecast to gradually back into the SW 
and ease during the course of the day. I hear a gale warning coming through in 
broken syllables on the VHF. I think that is for where we have just come from, 
to the east of Wilsons Prom. All is well. |
