With a beautiful day we had a nice slow morning with family and then got back to preparing our main and mizzen masts for painting (well we also washed the dinghy and equipment).
We now have all the wiring out of the main mast.

We have put messenger lines in for them all.
We have removed both winches (a single speed Lewmar 8 and a double speed Lewmar 16, neither self tailing) and all other fittings showing any corrosion.

I was a bit annoyed by the winch mounts. The winches has been fitted with bolts that were too long and so instead of beinfg simply bolted to the winch mount some of them has gone into the mast itself. That has caused more corrosion and extra holes.

So everything is off and the masts have had a wash including a wash of the inside with a hose.
We have decided we don’t have to do a perfect job immediately, so we have not removed anything that we still need and that isn’t showing any corrosion eg spreader roots, spinnaker pole track. Similarly we have decided not to remove winches and cleats from the mizzen (upgrades can come later).
Tomorrow, is clean with acetone, sand, clean and get a coat of primer on. Then we can fill holes we don’t need to reuse with thickened epoxy, then we can sand and clean before a 2nd coat of primer. That then buys us some time for the rest of the work as the aluminium won’t be able to oxidise.
Another task has been looking at all the hardware we need to fit to the masts.
We are now looking at re-purposing the existing Lewmar 16ST for our mainsail reefing. Then 2 Harken 20ST for the halyards. If we can find something suitable secondhand then we will go for that instead.
We are only going to fit 3 actual halyards and supporting hardware at the moment (Yankee or Genoa, Staysail, Main) but with messenger lines for 2nd headsail, trysail and spinnaker.
We are also going to upgrade from cleats to Rope Constrictors for these halyards, skipping all the generations of clutches. Rope Constrictors are about twice the price of a standard clutch but they don’t damage the Halyard at all. But a replacement Halyard is about three times the extra cost. We have found 2 sources Ronstan and Cousin Trestec.
We are going to replace the tired halyard exit sheeves with the newer, simpler plates (and go from 2 to 5 of them so we have support for all the halyards we will ever need.
We have decided to simplify the lighting. We don’t have a simple way to fit lights to the spreaders and get the cables into the conduit at the front of the mast. That means keeping the deck light and the steaming light on the mast Deck light is lower than the spreaders, steaming light is above. However, it looks even simpler to get a combination LED steaming and deck light. One less cable to run up the mast.
Anyway, painting and filling is the first priority. All the fittings can wait for a while.
