The RS600 - opinions and how do you tack

Speaking of selling 600 masts to cherub sailors - I have an old Angel mast for sale - its structurally sound, just corroding around the join between the two sections (approx 3 ft from the bottom of the mast) due to the aluminium/carbon reaction that eventually happens - I'm open to offers if anyone is interested??!!

Unfortunately so...

Electro-chemical reaction. Carbon laminates are electrochecmicaly active and erode aluminioum in the presence of water, very especially seawater. Corrding alimimium forms an oxide layer rather thick than the metal it replaces. So if you pu an alloy sleecve inside a carbon mast it goes fizz, fizz, expands, and breaks up the carbon laminate.

Originally posted by m_liddell How can manufacturers make such obvious screwups?

Usually because they are desperately paring costs and hope for the best. Very often they get away with it, cometimes they don't. Viz the thread elsewhere here about akicking strap fitting screwed into a wooden hog inside a glass floor. A common technique, but poor engineerng. Its usually got away with until a bit iof roit seeps down the scrtew threads or the boat gets especially big kicker loads.
