Looking for a Carbon Mast
« on: November 03, 2012, 12:44:57 PM »
I'm looking to try and source a carbon mast for our cherub(2654).  Whilst the old mast works, it would appear that it's about 12" shorter than other boats(Sweet Dreams, Loco Pero and Suicide Blonde).  The length seems to be missing from the foot and as a result the boom is incredibly low!  I'm quite happy to do repair work/add new spreaders etc.  I'll be doing a lot of work on her over the winter so don't mind adding a mast stump if required.

Let me know if you know of anyone who has a an old/broken mast that fits the bill.

Thanks

Tom

When i saw the boat last year it looked like the mast has come from a wayfarer and been trimmed to fit the sails.

Check the overall height from hull bottom to mast tip.  This should be no more than 7.1m.

If it is a bit short then a taller one would allow you to set bigger sails or set the current sails with a bit more clearance under the boom.

a carbon mast would be a lot lighter.  Old RS 600 masts used to be used for this. These are not as light as a modern carbon Cherub mast but lighter than an aluminium one. It is also easier to  lengthen a carbon mast than it is to make something from scratch.

They can be made and the materials/ consumables cost is about £300.

Thanks for the reply Phil.  I'm pretty sure the mast is shorter than the max height.  When she was sat next to Sweet dreams, Loco & Suicide they all had about 12" more height than our boat. 

The other thing is as soon as I pull on the downhall the tack is level with the boom(no more room for adjustment)  This has the effect of dropping the clew lower(the sails cut so that the tack should be around 6" higher than the clew) and thus the boom at the aft end becomes very low.

I've been informed that an RS700 mast should fit directly, an RS800 would require a little shortening and as you point out an RS600 requires a stump.  It's just a matter of finding a suitable donor mast at around the right price.
As I said before I have no problem repairing a mast if a broken one can be found!

If sailed in 97 mode there is/was no mast cap. So if she needs a taller rig to make the sails work, then that is allowed.

If you rig the cunno to one side of the boom you can pull down to and beyond the goose neck. In sucking eggs territory, but also worth chaecking you are really all the way to the top of the mast.

Don't get me wrong she can be sailed in current state.  However the sails are starting to get tired and before she gets a new suit the rig will need sorting.
