I have three spare Hobie 18 Masts. All of them are Hobie 18 SE masts, sorry, no SX sticks.
All three masts are Black Anodized, Two of them are all Aluminum, and one has a NEW Comp tip. All three masts are in Excellent to very good condition and are complete with Halyard, Spreaders, Diamond wires, Rotation Control and Mast Hinge/base
I Live in Colorado, but will be traveling quite a bit this year, so if you can accommodate my travel schedule, shipping could be almost free.
Most of the time, the biggest problem seems to be how to arrange shipping for a item 28'4" long, and even if you can get it shipped, getting it there undamaged seems to be a long shot.
I will be traveling to Florida for the Mid Winter's East event in March, I regularly travel between Denver and Dallas, and I will be going
to Vancouver for the H-18 NA's in August, and to Clear Lake in September.
If you are anywhere along the way to some of those places I could bring an extra mast with me. Asking $750 each. Pretty firm on the price as these masts are in very good condition and complete. Consider that just a Comp tip is $450 and Diamond wires are $150 I also have a new Comp Tip I would part with for $300.
