So NO seasoned sailor ever sails the southern seas in winter, is that your claim?
If you mean rounding the southern capes on multi-thousand mile voyages across the Southern Ocean, that’s exactly right. They don’t do it.
For the same reason they don’t climb Everest in winter either.
They only do it, it seems, if you are going to “age out” of a “youngest ever” record if you don’t leave RIGHT NOW, and damn the consequences!
(After all, you have two EPIRBs, so if it doesn’t work out, the world will mobilize to rescue your sorry ass.)
Travis McGee sails and you're beating on him for his knowledge. Do you sail? Have you read any sailing forums?
