Mast overhaul....

When I splashed TIH three years ago, I re rigged the mast but did not overhaul the fittings.  I took the opportunity during this hurricane season to pull the mast again and carry out some work.  This will include adding 32 mast steps (folding type), overhauling the sheaves and replacing the tangs.


I am still trying to ID the mast manufacturer, all suggestions welcome.  Dimensions are 9 7/8" by 6 3/8".

I will install a spinnaker bail on the forward end of the masthead (right hand side of this photo). This is to take a roller furling Code Zero (Facnor FX 2500). 

I really, really want to remove the SS bolts that hold the tangs on the mast (masthead and spreader) but they are proving a bear to move.  The Kroil releasing fluid is excellent.

Spreader holder.  The four rivets on the upper side had corroded away.

Spinnaker boom track.

Masthead sheaves (2 by 5"diameter by 3/4" rope sheave + 1 by 5"diameter by 1/2" wire sheave in the middle.  As I don't plan to use wire halyards I may try and swap this sheave out.

Dual backstay connection.

Movable goosneck connection for boom.

Is there conduit in there? (hard to tell from the picture) Having done this ten years ago on our sloop, I recommend using lots of Tef-Gel on the stainless hardware threaded to the aluminum. It dramatically reduced corrosion.

Hi Robert

Yes, there is conduit in the mast. One of the jobs will be to remove the new wiring and install backup rivets to hold the conduit inside the mast. Having once had a conduit break loose inside a mast, on a trip down the Caribbean, I never want to go through that again. 10 days of clanging every 30seconds was like living in a bell tower.

That might be a Klacko mast common to C&Cs from the '70s to the '90s.

Go to the head of the class. Klacko spar it is. Well bloody done.
