Lennon Sails developed and introduced the long cam system in 2015 and since then have developed the cam itself to make it more reliable, lighter and less aggressive on the mast. We now only supply the injection moulded type and have completely phased out the earlier printed versions. 

We still recommend using low friction tape on masts where the cam sits especially in sandy and gritty locations. Particles picked up whilst launching can get between the cam and mast causing damage over long periods to the carbon mast surface.

6 cams make a full set:
From the top (#1)

#1 short narrow cup dia
#2 short std cup dia
#3 long std cup offset entry slot
#4/#5/#6 Long std cup central entry slot
