What’s so special about this pole? A large diameter in the middle gives the aluminum pole strength where needed. Also, tapered ends and the smaller end fittings they afford greatly decrease overall pole weight and increase ease of use.
These are easy to maintain, too. If the epoxy cracks over time, all you have to do is brush a little more on.
This spinnaker pole is built the same way for the Lightning, Flying Scot, and Thistle (other than length).
