Thanks.I'm comparing the Aerons + Prolimits.. weight will be the decider I think.I need c 175 - 235 or at least 212 long to fit my 7.2m.

I'd like to buy another but windsurfnsales has sold out and I don't know where else to get one?

Whats wrong with the Gun booms from Windsurfnsales ?

I have one, it is exactly the same as the Aeron MCT26 I bent (except for grip colour, logo and extension clips) and it was cheaper.

Unfortunately I am not sure that you can have both 'good' and 'cheap'. But the Gun ones are certainly good enough, with a 26mm grip as well.

I also have a Gun Boom they seem OK and at a good price.

I had a North silver when I first started and it was really good, Nice diameter and tuff....I was learning so it took a pounding. I think it was around $200 brand new.


second that, im 115kgs fit, mines handled forwards, backies, freestyle not a problem, a bit bouncy but strong.

I didn't even see the option. I looked up Loft and they were all sold out..Might be the way to go as his customer service was great and cheaper + lighter than the rest..

The vee grips are very stiff, I was testing them out against a carbon boom and I couldn't make either of them flex all that much..... I recon the design definitely works... where as a standard alu booms have quite a bit.....

I think lightness wins for me I don't know that at my weight I'd notice the extra stiffness. If the boom was for my smaller sails Id go for the extra stiffness but as I'm already struggling using all my strength to uphaul the 7.2m I don't want to make it any harder!

Why is boom stiffness so important? It's been said that when the boom flexes in a gust it gets shorter, powering up the sail when you don't want it. When you do the boom flex test, do it with the head firmly on the floor and the the tail against a pencil mark on the wall. Note how little flex is transmitted to the tail end for quite a bit of flex between the arms. It's all simple geometry. Aluminium has a nice comfy feel and if you do get tangled with it in a big crash it's more likely to progressively crumple doing less damage to you.

I think for me the stiffness is more about transmitting my effort when I try and pump the sail, into the rig more, instead of flexing as much as aluminium does. I do like the idea that the carbon boom should last longer for me, as I have broken an aluminium boom almost every season since I started, and at a lardy 100kgs, it becomes more of an issue.

I got a very short season (3 months) out of a well known brand and I think the reason was that at my weight I cause the boom to flex more, more often, and the aluminium fatigues at the head.

For aluminium booms, the stiffness translates to durability.

YM for Al is around 70 GPa. Carbon fibre in epoxy is over double that. Aluminium is at a disadvantage here, it's easier to flex it, and as it flexes, it becomes more fatigued (in alloys, strain is a good predictor of failure), and more likely to fail.

As for comfort and crash absorption, yes, agreed it's better to have the flex.

I work on the pricipal that if I never try a stiff carbon boom I will never know the disadvantages of an aluminium one !

I think back to the days of tie on timber booms and think how fantastically good my cheap ali clamp boom is.

Ignorance is bliss.

Hi, from Jordans in Port Macquarie , i have the prolimits v section boom which is the same as the aeron , and rrp on those are $229 and i stock

email [email protected] or www.jordans.com.au


What do people think of these?


I've had 2 Pro-Limit wave booms in 5 years. Only replaced the first one because it had been sailed hard and didn't owe me anything and I figured I replace it.

I'd definitely recommend them based off my experience with the smaller ones.

I worked on that principle.... then a mate let me have a go of his rig.... it was terrible.... light, responsive, controllable, just felt like getting out of a Datsun 120Y and into a vehicle made post 2010......

There are a lot of down sides with the performance of good kit, it means you spend more time trying new things and less time just surviving......

I briefly owned an Aeron 160-210 V-grip last year. I replied to a review in the gear section for those interested. In summary, due to it's weight and profile (and my weight and style), I didn't find this boom suitable for either for B&J or slalom so sold it. However, I think the V-grip design concept is brilliant (and Aeron make really good stuff in my experience). These booms would make a wicked slalom boom if they had the width (to bag out the sail). If Aeron ever make an extra-extra wide version of this boom so that I could bag out my 6.5 race sail on it, then I would buy one for sure.

Ian K: Thanks for pointing out the flex/power up phenomenon of alu booms. That's an excellent point.

Just one other thing I do like about alu booms. Pumping on the plane. My last boom was a Sailworks slalom boom. It had quite a bit of flex. It was very easy to pump on the plane than any boom I have used, as the flexing of the boom allowed me to resonate the pumping motion of the rig (similar to pushing a child on a swing).

I've ordered a Gun boom from windsurfingsales..It was the lightest of the choices..Thanks everyone. Might consider the V profiles for a smaller boom in the future.

I used my new Gun boom for the first time today.5.8m KA Kult in c 12- 20kts mainly 15 -18kts. Very impressed by the rigidity and comfort of the narrow tubing.
Down side was as a woman I found it hard to have the strength to put it on and had to hold the clamp and use my feet/ legs to push the mast out to get it off. I'll have to make sure the boom is at the right height as I won't be able to adjust it on the water.
I may just need to learn a new technique for rigging / unrigging.. Love the solid feel to the rig! The old one must have a had a lot of play. This one doesn't creak either!
