Re: Question about Banking a boat
I hate to beach, but I do it a lot . . . I use a slide hammer stake, anchor, deal, thing that drives fairly deep into the sand. This thing is made for beaching and if you pull the line tight enough the stern won't usually swing.
Slide Anchor (this one shows being used to hold your stern secure at anchor, but everyone uses them as I described where we boat, which is where they are made)
Also, a huge tip for you . . . get every one to sit as far aft as you can when you come onto the beach. You don't need to drive her up on there hard. Then when every body gets off (you too), pull up on your bow and onto the beach. Pulling up is key. If you do your beaching with any weight forward, she'll fail to stick every time once everyone gets off. Same thing when leaving. Either mover her deeper before everyone gets on, or have them all go to the stern or you won't get her off without a bunch of power in reverse . . . If you do this and use some sort of good strong tie up to the beach directly off the bow eye, you may get away without the second line. Also, keep and eye on her. If she starts to move off or turn a little, drag her up and on again. Sometimes it takes constant maintenance.
