My H31 has a wheel lock/brake and I have not owned a boat rigged with one so I'm not sure exactly how to use. I searched the archives but don't see the purpose of the wheel lock? When in the slip, i tighten it down to keep wheel movement to an absolute minimum. Can the wheel lock be used while underway to go forward to work with sails? is this safe? Is it a short term use for auto steering? As always, i appreciate all feedback given. thanks, Jerry
