Re: How to Choose Correct Whiskerpole

You could use the smaller pole if you took care not to overload it. The bigger pole gives you a better safety factor at the expense of more cost and weight and more awkward to handle. Is your boat a ketch with large genoa or cutter with large genoa or smaller yankee? If your headsail is not a large ...

In the photo above you can see the shoe is stainless plates with a thick-walled pipe welded onto them for the shaft to fit into. Drilling and taping stainless is tough but maybe a local machine shop could countersink the bolt head and tap the other side.

Re: Masthead casting

The new mast on Trion Osprey was Z351 from US Spars in Gainesville, FL. The masthead fitting is for internal halyards and the chances of it fitting some other older mast are remote. Modern mast sections are all different shape from older designs like yours. Unfortunately there is no standard shape.

As for damaging the inboard end of the pole it's just a matter of not putting a pinching load on the cast aluminum jaw by having it jam in the mast eye when lowering or raising since the pole acts as a long lever arm and forces can be large. Otherwise, they are not prone to being damaged.
