They do not. The rules include the possibility of slowing, stopping or
reversing.

Simon, you wrote:

If I determine there is a danger of collision I change course -
I'm certainly not going to take all sails down and come to
a stop and become a sitting duck


Are you saying that in restricted visibility, you would change course
regardless of whether you had a visual confirmation of the other vessels
position?



Yes I would. The Rules require me to.
