Re: Docking in current
If it's 2.1 kts, can you point into it in the fairway, power slowly forward, and hold the boat in position? If so, you could effectively (maybe), back into the slip while still in forward, reducing throttle a bit. I'm thinking that you never use reverse in this approach. You'd need to be careful to never loose the bow, you'd have to keep working the rudder so that the stern stays directly behind the bow, and into the current....even if you're not initially aligned with the slip. If you loose the bow, you'll surely end up pinned against the pilings as indicated.
I hope you have good rub rails, that will help if you end up against a piling. If the rub rails touch either piling on the way in, you'd still have some control of the stern, again in forward all the time.
It's a tough one! I knew a guy who got good at this in Newburyport...he practiced the drill near some moorings before trying it in the slipway. Master this and you'll be one good close quarters boat handler!
