It should be doable... use the backfill technique if you have an outboard.

If you have an inboard, you can still do it, but it'll require more
shuttling back and forth.

I'd suggest practicing it say between mooring balls before trying it at the
dock. Make sure you're fenders are out, have plenty of hands on deck to help
the first couple of times, and don't get going more than enough to maintain
headway. Remember which way the boat turns better, both forward and reverse
(prop walk), and use this to your advantage.

Of course, backing up 90 feet shouldn't be a big deal either.. that's just 3
boat lengths, and you'll get a lot of practical experience with prop walk,
which will help you when you finally get sick of backing up. g

Question about a pivot turn, is it possible to turn around a 29'
sailboat in a 40' wide area?
The only space available at a nearby marina are side ties and I'm
worried about whether I can actually dock there.
Before starting the turn the wind is at the stern. On the port side is
the marina wall and on the other is the dock. I don't think there's
much if any current affecting the slip.

The other option is docking with the stern to the wind and when leaving
backing up for 90 feet.
There are boats in front and behind this slip.

Thanks.
