I sometimes carry two poles, so in addition to the mast-storage option, I have deck-mounted chocks for the second pole:
These are from Forespar. I have the upper version, without the wire guards.
There are also stanchion-mounted holders:
These are also from Forespar. C.S. Johnson makes similar hangers.
I decided against the stanchion-mounts, as I was afraid of getting the sheets
tangled on them. I do see then used on other boats, so perhaps this isn't a big problem.
The deck-mounted chocks are indeed toe-stubbers, and the stowed pole does take up a lot of the side-deck. When I'm only carrying one pole I keep it on the mast. It would take a lot of wind
before I felt I needed to drop the mast-mounted pole, and I would probably have already bagged my roller-furling headsails by that point. I occasionally sail in 40-kt winds, and the current
arrangement is has been fine so far. Of course, VALIS is a big, heavy, boat.
There's no reason you couldn't lash your pole on-deck, but it's not going to be particularly convenient.
