In the open sea A current will allow your boat to keep the angle set. On S.F Bay it will move the boat all over. The current is eddying, and swirling like mad. It depends where you are on the bay.
Until you get a smaller headsail on the boat. I would just duck behind Angel, Alcatraz, the city front, T.I. or Sausalito. In the summer time that 150 is good for early morning, or late evening. During the day you need something much smaller that will reef, and hold it's shape. For 17 years I was at the end of the slot in Emery Cove, so I have some experience with what the bay offers.
Since you were succesful with your pprevious boat. I would imagine your problem is not being able to balance the boat. You could always roll the headsail up to a smaller %. Even it has no shape just to Hove to.
Did yyou get a chance to go out, and sail with the Polynesian canoes when they were on the bay?......i2f

Sure Adam, I"ll agree with all of that. The only reason I brought current up, was because the OP, Mark, sails in SF Bay where I understand there are strong currents....does a 5 knot current matter, in 25 knots of apparent wind...? I can't say..it was a " it might be a consideration" comment...
Yes..apparent..is what we sail...
I know, in the Hudson River with up to 5 knots of current, I have to make adjustments to my rudder angle to get the boat to lay the way I want it to sometimes.....it's not simply a matter of putting the rudder hard over...
To your point about, heaving-to in 10 or 15 knots of wind ( A) in a 5 knot current, that's often what I need to do...to demonstate the manuever...

For the purpose of deciding rudder angle, I don't imagine anybody ever explicitly considers current. They just adjust things so that the apparent wind is coming from where they believe it's supposed to be coming from in order to be properly hove-to. This decision indirectly takes current into account, since current affects apparent wind.
It's important to note that, really, currents don't affect apparent wind enough, most of the time, for it to make a different for heaving-to. If you're in 10 knots of true wind and you have five knots of current, probably you shouldn't be thinking about heaving-to. If you're in 35 knots of wind and have 0.5-1.0 knots of current, then current is probably the last thing on your mind.

|MarkSF||Surely the rudder position is a function of the physical characteristics of the boat - keel size and position, size of jib and main, and so on. All the current and wind can do is change the course and heading of the boat when heaved to.|

If you mean "same true wind" then the current will create an apparent wind that has to be taken into account.
