Orange draft stripes. Orange = fast, and also = VSpars?

Interesting main reef distribution. 1st looks sorta nominal (aligns head to I-point I guess), then 2nd is many times larger. Is the 2nd reef dictated by some other consideration, like location of upper spreaders or an inner forestay or running back attachment?

Looking at the sail designation code on the tack of the main it reads OMN-A. Guessing that means it's their offshore main.

The offshore boom will have many more layers of carbon to deal with the compression loads generated by the move in the position of the clew when reefed. When the clew moves in the geometry of the forces changes from the regular placement of the vang, clew, mainsheet, and gooseneck to a different placement of the clew further in on the boom, while the mainsheet position does not change, but the forces stay the same.
It looks like the first reef goes to the houses, and the second goes to the top set of spreaders; probably something to do with the strength needed to support the loads of the square top main.

On rough guess-trapolation, I get the checks to be at the second spreaders, and the 2nd reef lands the mainsail head at the 3rd spreaders. Looks also as though the square head might clear inside the topmast backstays when reefed to the second reef (but obviously not the checks).

It's not unheard of. You can make booms really light if there's no reef points etc.....


Latest post

Mentions offshore boom, is Team Bella Mente going to swap out booms for inshore and offshore races?


Really lighter? How much lighter are you going to make a carbon boom? Take out two spinlock jammers and reef lines and the boom is what 6-8 Ibs lighter?

Serious question, what is the difference between an offshore boom and an inshore boom? Maybe layers of carbon? I know from experience, carbon vs. water, water always wins. Maybe a thicker boom gives carbon a fighting chance against water.


I know Scarlet Runner has two booms, you can pick up the inshore one easily with one hand. I think the offshore boom is substantially heavier, remember the offshore one has to be able to withstand 50kt winds, they aren't going to race an inshore race in those winds. So that's a lot of extra carbon plus reef lines, sheaves, and clutches... It's enough weight for it to make a difference.


and it doesn't bump the rating? inside the ???kg varience that prompts a re-rate ??????

Can't say I know what the deal with the rating is. All i know is they have it.

There exists an IRC Cert for Bella Mente as of 1/20/2012 at 1.599. This surely isn't a final number.

Previous boat rated at 1.540.

Sure, it might. But these programs have different certs for offshore and inshore anyway - in fact, they might have different certs for (almost) every event to reflect the customizations and modifications (sail plan, keel/bulb, other appendages, etc.).

Ehm, Under IRC (primary rating rule for Mini-Maxis) you are only allowed 7 certificate changes a year and you can only have a single valid certificate at any one time. I know, that is probably not far off the number of events they will participate in but experience and settings will not be transferable with big changes and that counts for much more than a point or two here and there. Plus these guys are more likely to have reef locks than the spinlock jammers, like on the Volvos.


The difference in boom weight inshore/offshore is not much more than the food and drink that gets packed for a single day racing with 20 or so crew.

The real interesting thing based on the photos is that it looks the guys have gone for inline spreaders compared to al the swept-back rigs we have seen in the mini-maxi fleet so far. That should reduce the compression in the tube so BM probably has the lightest tube of the mini-maxis and can get away with lighter rigging as well. It will result in a rating penalty (IRC) though and obviously you need some pretty switched on guys on the backstay, runners and checks.

Wouldn't you just get rated with the lightest boom and as long as the E black band measurement was identical you should just swap it in and out?
Off shore the boom weight can be managed by freeze dried over fresh or a watermaker going in.

The boat will be doing mostly offshore this year, and you'd never use an A3 around the bouys. I'd guess the furler going to the bikes is as fast as a takedown line, and much more controllable for the reaching kites

Laminate A3's are a mofo to handle... especially on that scale so sometimes furlers are a much better option... that one looked like a top down? I know a few boats in the Southport race last year had their A3's on a furler at the end of the sprit and the A0 on a furler either at the bow or halfway along the sprit... leaving them both hoisted and ready for action allows for very quick changes without having to send anyone forward when conditions were heinous.... makes a lot of sense.

Yes, it is a top down. Definitely a good idea.
