On poles, @ 2", you'll be wasting your money. I say as much, as I'm pretty sure that the pole on a J-24 is 3". So for them, running a kite is probably on par with a rather svelte jib on a 30'er. And on a 35' boat, a 3" pole is pushing it at times.
If you find some end fittings, & want a wooden pole, to save $, you can laminate up your own blank, & carve it by hand. Or have someone turn it on a lathe for you. Though in truth, only the ends of the pole HAVE to be square, so that they'll fit the fittings.
So to do a wooden pole quick & dirty, you can take a square blank, & cut it to be 8-sided, on the table saw. Or bullnose the edges of a square blank with a router.
And the standard finish is clear so that you can see any rot beginning, early on. Just seal the blank with epoxy, & a light layer of cloth or two (maybe spectra, polypropylene, or dynel). Fill in the weave with epoxy. And then put on a bunch of coats of varnish to protect the epoxy.
Or, go KISS, & just keep it oiled.
The most secure & user friendly pole ends are:
- The socket type on the inboard end. Usually Forespar's TS or UTS model
- Something with both an automatic, as well as manual trigger on the outboard end. That way, when you jam the line down into it, it automatically traps it. Or, you can use the manual trip line, to both lock it open & shut it's jaws.
There are a plethora of makes & models.
Most are going to look spendy, but unless you're practiced at/enjoy trying to manipulate a pole with more complex, but cheaper ends. A 3-handed job, while working to keep your balance, hands free, on a rolling foredeck, then the more high tech ends tend to make sense.
Pull up a YouTube video of them jibing a J-24, if my description's unclear. And why I'm a fan of the fancy end fittings. Watch the simultaneous juggling & balancing acts, especially if there's any wind. And keep in mind that most bow guys & gals who do said job, have hundreds, if not thousands of hours on the foredeck... in ALL conditions. Ask me how I know ;-)
PS: A cheapish source for a 2" pole is a used windsurfer mast
