ive broken 2 masts this year both cam sails and both times while rigged on the grassed rigging area, both were 100% skinny's and the same brand,the sails were n/p 4.6rs 400 mast and a 6.2rs 430 , i'm wondering if the race sails have too much pressure for the skinnies, and is there anyone out there useing skinnies on there race sails
Hi Keef i use RDM masts in my Loft Blades for over 2 years now with no problems the sails are designed around the RDM's,surprised that you have broken 2 RDM's was there any cam wear into the mast? and where abouts did they break up in the top half?
What type of cams do you have in your sails the original NP or did you replace them with RDM cams?
Leaving the sails in the sun might be a problem but i've had my sails sitting in temps of around 45 deg although only for a few hours and not all day.
100% race masts (SDM) break commonly, but quality RDMS seem almost unbreakable.
Were they secondhand so you don't know their history? Could have been dropped and therefore weakened - doesn't take much to fracture carbon.
What brand?
Sorry forgot to asko too - how old?
KA masts in KA sails, even if out of warranty you can claim form the manufacturer as thye didn't last as long as a reasonable person woudl expect the average mast to last --------- if they haven't been dropped or abused

KA masts in KA sails should be good.

Hi Keef,
Black luff pockets left in the sun will kill a mast. Anything over 80 degrees C and epoxy will start to break down.

Ok rigging a 400 mast in a sails made for a 370 means the boom might be too far up the mast. Also the mast being too stiff and/or opposite bend curve might not help.
