Re: Docking with a spring line questions

I do think the major problem is that your prop is so far away from the rudder there's no 'propwash' effect on the blade and since you're stopped it probably doesn't matter what you do with your rudder... ergo the trick is going to be finding that elusive 'sweet spot'.

Does is make any difference what position the rudder is in?

I like the idea of an moving the spring nearly to the stern too...

Re: Docking with a spring line questions

capecodda, bljones - thanks, it's making more sense now!

chef2sail - you talk about a second line but shouldn't the first line prevent the boat from reaching the head of the slip? how sturdy is the jib track cleat? i don't have anything behind the pad eye other than stanchions to tie to...

Faster - i haven't tried any other rudder angles but it does make me wonder how much effect the rudder angle is having given the distance from the prop. i know if i give it enough gas with the wheel hard away from the dock the stern will swing in, it just makes me uncomfortable having to throttle up so much with a bunch of cement and wood about a foot in front of the bow!

Wont that allow you get too far into the slip before stopping the boats forward motion with little room for error?

By being on one end or the other ( bow/stern) wont it allow the opposite end to blow away from the dock?

Having your first line tied up being in the midship area kind of prevents that.

Re: Docking with a spring line questions

Hey,

I thought an 'advantage' of the saildrive was no prop walk.

Personally I *like* the propwalk I get on my boat. By shifting into reverse and revving the engine up I get almost the same effect as a stern thruster. The stern will swing to port while the bow doesn't really move.

Of course, getting off the dock is a different story....

Unfortunately I can't offer any advice on getting into your slip.

I wasn't talking about two lines. One line. One end ( loop) around a robust jib track cleat set just behind the midline( wide part of the boat), the other end of that same line to the dock cleat or piling tied aft of the middle of the boat to prevent the boat from hitting the head of the slip. The fixed line is the first you grab and drop over the midship cleat when you come in.

Re: Docking with a spring line questions

FWIW the propwash on your rudder will not push the boat to the dock. Propwash serves only to rotate the boat, you use the right rudder and propwash to rotate the boat to establish and maintain it parallel to the dock, fighting the tendency of the wind to push the bow off (and to a degree the boat...). You need the forward power to push the boat to the dock - more breeze, more power.

You have two different controls which need to be used together but understanding what each is capable of doing. Advice, use the propwash to line the boat up parallel tot he dock before laying on the power to bring it against the dock...adjust your angle with the rudder, your distance to dock with power.

Re: Docking with a spring line questions

Faster is probably correct in that your rudder is not doing much by the time you are up against the dock.

I would suggest finding a long floating dock with lots of cleats to practice on. Maybe your fuel dock on a nice night. Just keep repositioning lines until you get it right.

Once you find that sweet spot for the spring line you should be able to hold the boat gently against the dock in forward with varying degrees of throttle depending on wind/current speed.

Re: Docking with a spring line questions

To the OP:

The key is a mid ship cleat. Anywhere from the widest point on the boat to a little aft. Once that is in place the thrust will keep you in place and yes the rudder will help. The placement of the rudder is different on most boats, but not by much. Get a line running aft from the MID SHIP cleat postition and you will be fine. Anything forward of that positon and I don't want to be your starboard neigbor with that big stern coming at me.

Go to Quantum Sails website and pull up Capt. Jacks videos. He has a good one in there on exactly this subject. Rocket science this is not! Simple physics!
