HI , I wonder if anyone can help me.I thought I owned  an NSM 4 but I have deduced 3310 is an NSM 1.Does anybody know what the ideal all up weight would be for an NSM 1?

About the same as an NSM4 actually I'd suggest typical ideal weight (it will vary though with the mast type) of about 22st inland and 24st on the sea.

Thank you for that..not sure which mast..proctor alloy will look at what section.How many different types are there?

I'll be a D.

Good all rounder in the day.

When she was new there were several proctor masts to choose from likely types being M1 (fashionable for lightweights but relatively easy to break) or M3 (bit stiffer/ sturdier).  M7 came in soon after as a good compromise slightly more flex than M3. Internal sleeves to stiffen around the deck/ strut were common especially for the M1. Other more recent sections will have been used as near equivalent replacements.

Anything M will be a Superspar section. M3 was the D equivalent if memory seves.

I'm pretty sure that the Beta Minus had gone out of fashion (maybe discontinued?) by 3310, leaving the D as the Proctor section of choice.

Apologies ignore all that the M series were Superspars not Proctor. Kappa was another slightly lighter/ more flexi Proctor section sometimes used as an alternative to the D but not by very many people.

Thanks chaps for this>> will lookat mast when next at club this weekend.
