Sorry. Your route
cannot be calculated in advance
Other than it will be southerly.
Just go. You can figure it out later. Any bad season, weather-wise, can be avoided with any number of pleasurable diversions along the way.
I was just about to leave Borneo for Palau
. But I tore up my favorite genoa
so I'm going to hang out in Kudat for more than a few days of sewing and fooling around. And just now, surprise, some cruiser friends showed up and more are on the their way...good thing I hadn't made a real plan....
