Thought you guys might like to see the mast we are currently manufacturing.
It's for an S&S 34, going from the old deck stepped single spreader rig to a taller, keel stepped double spreader rig.
Boat is doing the Melbourne to Osaka.
This pic shows the masthead unit. Has a large backstay crane as shorter hoist but larger roach is better for IRC.
Also note grommets for kite halyards, no blocks to fail.

This pic shows how we do our spreaders. Band is only for reinforcing, there is a plate right through the mast and into each spreader. The mast is compressed with a clamp, spreaders installed then clamp released, meaning no movement in the spreaders

These are our inhouse made grommets. They have a thread and are simply locktited in. These are for the lazy jacks.
We also use them for mainsheet take offs through the boom.

Our goosenecks for vang and boom. We never weld anything directly to the mast, in fact we pretty much use metal threads where possible instead of rivets.

This rig will also have Dyneema stays. Here are the spreader tips with oversized holes for Dyneema with chafe guard.

Quality local manufacturing!!!
