You're able to maintain a LOT more control over the pole by always leaving the butt end connected to the mast, so long as you're using the pole. And by running your foreguy to a block (or two blocks) out at the bow.
One of the key reasons being, is that if you do end for end gybes, via detaching the pole both; from the mast, as well as the spinnaker guy at the same time. Then the person working the pole, needs both hands on the pole in order to do this.
And is conducting the end for end pole swap, all while balancing on a rapidly moving & pitching foredeck/cabintop. During which time, they're now trying to snag the new spinnaker guy with the outboard
end of the pole.
Followed by then locking the (now compression loaded) pole back onto the mast (usually at head
level or higher). While still having zero hands free with which to hold onto the boat.
So unless they're really practiced, & confident, it's a hairy drill.
Pull up some youtube videos of J24's. As they do end for end gybes exclusively, & it can get "interesting" being the foredeck guy, wrestling with the pole during a gybe. For example
- Keep in mind that most of the tutorial, kite gybing footage, is shot in very calm winds & seas. Where as in 15kts, with 5' swells & any kind of chop, & the bowman's dancing on top of a proverbial moving bowling ball.
I've raced on 95% of what's out there. And dip pole gybes, where the butt end of the pole stays on the mast, are the way to go.
With a dip pole gybe, the bowman sits in the bow pulpit facing aft, braced in place, & holds the new guy, while the mast man simply swings the lowered outboard
end of the pole in front of the bowman. Who has both hands free, while seated in a secure position, to lock the new guy into the pole's jaws.
Where, once that's done, the pole is re-raised, & swung out to it's new position on the other side of the boat.
- Also, in a pinch/if you're short-handed. Using this method, the bowman can simply grab the foreguy, pull the pole to him while seated in the pulpit. And then lock in the new sheet.
From there, the trimmers can pull the outboard end of the pole, up & aft. And you're back in business.
It's a lot more controlled, & safer. So unless you're racing in a one design fleet, where your choices of hardware
are mandated, it's the way to go.
Especially as it's a lot easier manuver to perform, given that everyone is holding onto the boat in one way or another, all of the time. In lieu of doing the free handed, guy spearing dance, in front of the mast (end for end gybes).
There are a couple of hardware
setup diagrams here Harken
but odds are, youtube, plus a few rigging/tuning guides & books
are your best bet. That, & or an experienced hand.
PS: In case it's not clear, I'm advocating leading both your topping lift, & your foreguy, to the outboard most end of the pole.
