☝ What Alan said.That's a pretty nasty kink. I fear that if you try to repair with a dowel, the area will still be weak, even with the dowel in it. That said, give it a try and see if it works. You have nothing to lose but your time and the cost of the dowel. Alan Glos Cazenovia, NY
Thinking on this some more, I'd be tempted to spend that money on a CraigsList used Sunfish. More parts than you could ever use, and Sunfish spars haven't changed. I'm not sure how I ended up with six Sunfish (now five).Klemsaba,
I can sell you a good used boom with blocks and end caps for $50, but the problem is shipping as any Sunfish spar is considered oversize and has to be shipped by a freight carrier at big bucks. I am in Central NY, near Syracuse. If you are interested, are you close by or have a way to pick up a spar here?
