This looks really fun! Lots of alternative routes I guess. :-)

Or??

They've also raised the race level from 5 to 4, with a price increase from 10 to 15 accordingly.

Same level than the leg between Cape town and Freemantle!

It’s Fremantle (not in Austria). But better not stop picking up spelling mistakes especially not on the French site

Looks like the main choice is left or right of PNG. The boat is not fast enough to go further East than that.

But there may be a cyclone developing in the Philippine sea in a week, and the outlook may be quite different from the current one.

can you add a map for it? or do you do that when leg 6 is closed officially (24/1) ?

There could also be some question of whether to go above, below, or through the Philippines.

How good is the router at considering options through the Philippines? I have a rough sense that it might avoid those routes in favor of more open water. If a good route existed through there, would it show it?

would be nice to be able to 'force' routing options, such a north of Philippines, e.g. by means of routing-waypoints

You can do a bit of forcing, by moving your start and finish places around to establish a route that would pass through the desired area at the desired time. Usually if it's impossible to find a route that would do so because the router is willing to go way out of its way to avoid the area, then that means the area isn't a viable option. The reason I asked this question was because I was trying to do that a bit with the Philippines. I tried setting destinations just to the West of the middle of the Philippines, and it refused to route through the Philippines to get there. It wanted to go around to the north or the south. This means either that the routes through the middle are so awful that it's better to go around even if your destination isn't far away... or that the router is having trouble assessing those options.

If a Skipper had chosen a good route in the VOR4, Melbourne/Hong Kong leg, would that route be suitable again, if the winds are favourable?

I noticed Skippers who were doing well early-on in the VOR, on the western routes, getting bogged down in the islands and losing their good leads, to the Skippers who went east and then headed well north to the open seas, before then heading west to Hong Kong. Sanya isn't too far SW of Hong Kong.

Does the minimum 4kt winds in the islands favour the Clipper with the Clippers lower top speed? Making going through the myriad of islands west of New Guinea less of a handicap?

The starting location in this case changes things. Coming from Whitsundays, sailing as far East as the Volvo leg winners went is unlikely to pay off (although that doesn't mean it can't).

The 4-kt minimum windspeed definitely makes it easier to get through routes that real-life boats would never try. I'm not sure if they help Clippers more than other boats or not, though. With the 4-kt minimum windspeed, it becomes more about wind angle than wind speed.

One big difference between Clippers and Volvos is how they perform upwind versus downwind. Both boats are better downwind than upwind, but the Volvos are MUCH better downwind whereas the Clippers aren't as dramatic a difference. So... In Volvos, it's worthwhile to sail a lot of extra distance in order to get a nice fast downwind reaching angle to the finish. Whereas in Clippers, you can't justify as much extra distance.
