It’s no where near as clear cut as that with the British moth . It’s much more important what hull you have rather than what rig you use . 
Most of the pointy end of the fleet are using boat out of the claridge/JJ boats mould. Other designs have their strengths but at the moment this design seems to be the best all round design .

I have no difficulty stepping a Enterprise mast on my own, presumably a carbon mast wouldn't make much difference to me, other than capsize weight.

My Osprey tin mast is still competitive inland against the carbon.

And not having to fret about varnishing against UV is good.

But perhaps the option of carbon repair rather alloy replacement may keep some older boats away from insurance write off?

The carbon mast is roughly half the weight of the M7, I weighed mine with rigging and calculated the weight of the wire to get back to the mast weight. With shrouds, forestay and halyard the M7 weighs 7.8kg, the Carbon, 5.3kg.

Weight aloft does make a difference even when upright but I think the performance advantages are mostly that it's more forgiving rather than actually faster. I have no difficulty stepping the M7 but stepping the carbon mast is very noticeably easier.

Some Blaze sailors prefer the M7 and it doesn't seem slower than the carbon stick. I agree about varnishing too.

Totally true and several National and Inland championships have been won by alloy masts against carbon since they were introduced about a decade ago .... including this year.  There is a weight advantage for carbon but overall you would not know which is likely to prevail in any particular event in advance.  The standard North sail sits very well on both options

Why bother going from a parallel tin mast to a tapered one? It will certainly make the boat more manageable in a blow but they'll all need new sails too as the curve will be different. Might as well go for a carbon stick straight away.

When I was considering a Streaker I found an article where the current or recent National champion sad (something to the effect of) "we all know the Streaker is 'difficult' offwind in a blow" so I decided not to buy one. If they had a carbon rig I may reconsider.

WRT carbon booms, they hurt a lot less if you get it by one and that's enough to convince me of their value.

After talking to a long term streaker sailor and class committee member I believe there is quite a lot of opposition to the change to a tapered mast . Even though the choice is a tapered mast or no masts at all ! Sailors can be a strange lot lol 

Re changing to carbon masts, there is one very good reason for not changing and that is cost. I know from looking into it with my class a couple of years ago. A that time a aliminium m1 tapered mast was @800 while a superspars carbon mast was about twice that . That’s a lot of money to spend lose less than two pounds in weight and when the only proformance advantage only happens in extreme conditions when I wouldnt be sailing anyway . On the other hand I did buy a carbon boom at that time  Smile

The advantages of carbon on unstayed masts are undeniable. To my mind the advantages on stayed masts are less clear cut, especially  if you factor in the extra cost. 

There is a Topic all about the how the Streaker mast which  I think is a new class of mast: the barely stayed mast. The shrouds are very slack.

Don’t get me started, white pigment or paint them white. The dark side that is marketing has decided the must look carbon

I was going to paint mine white but was told the recommended white two pack is not UV resistant and you still need to varnish on top which seemed a bit of a waste of time and money.....

I haven't got around to it yet but will investigate car paints and rattle cans before I spend £70+ for the 'proper'stuff.

Titanium dioxide - standard white paint pigment - is a standard ingredient in suncreens, and International claim their topside paints are specially formulated for high UV protection. I would be very interested to hear the justification from whoever told you that...

Probably the most of topic thread ever... but still really interesting and positive.

If you’re ever up in Harrtlepool you can drop in on the Huntsman Titanium Dioxide plant. You can also pop in in the Able oil rig recycling plant.
