I have two sets of lines ! (and a few more emergency spares )
I keep the stern and forward spring line connected to the dock, and the bow line comes with me, secured to the pulpit..
When I approach the dock, my first plan of action is to pick up the stern line, and drop it over the stern cleat, then continue forward until someone can get onto the dock and tie up the bow line, then slip the spring over a winch..
Worst case scenario (last night) I can't catch the stern line, and start drifting towards Jerry's boat, and start the "I'M GOING TO BAIL OUT IN 10-9-8-7-6 etc." countdown.. at which point the admiral is pointing away from or towards the dock...
Bailed out once last night.. did a "iron genny gibe" and caught the bow on the second try, grabbed the spring, and moved her into place..
Can't wait to see how this pans out on a 30+ boat !!
