Carbon definately the way to go when making a ball protector

I find you can't bend the alli in a tight enough radius for myself

Athough It does look good when polished


YA all be cool

IMHO

Carbon:

pros..

- light
- stiff
- doesn't go sloppy at the joints after months of jumping

cons..

- can be expensive
- replacement bits like head can be expensive
- no warning that it is going to break. They generally just go snap
- some parts seem to go brittle where UV has effected the resin

alloy:

pros..

- cheaper
- can be light, but usually won't be very strong
- lots of second hand bits around to use to fix it

cons..

- generally heavier
- jounts where arms join head go sloppy after jumping many times
- new replacement bits are sometimes pricier than the whole boom
- the tubing is usually a wierd diameter and is extruded (apparently), and this type of tubing is not available in most shops. The stuff you buy from alloy shops is softer than the material used in the boom.
- everything seems to be made by North. Aparently North booms are notorius breakers when used for jumping. I must agree with that coz mine too lasted barely 12 months. If you are a gentle slalom sailor they are probably as good as any.

generally speaking

Also have to agree with Justan. My North Ali boom went coming down from a pretty piss weak jump. I dont think strength is their greatest quality .

If u can afford it go carbon. Its lighter, stiffer, and makes your rig feel heaps better. Can get real nice reduced diameter aswell .

Hope this helps.

Hmm ,carbon or alu.

It is not as straight an answer as the above think.
Firstly there are good and bad alu booms, and good and bad carbon booms.
A good alu boom is much stronger than a bad carbon, so don't spend more just cause it's carbon, look at the fittings as well. A boom is only as strong as it's weakest part!!!
When would i use carbon.
Anything over about 7m needs a carbon for the stiffness. Below 7m hving carbon is a luxury.
When would i use alu.
Wave sailing , if i could not justify paying more .

Take a visit to Hydrodynamix in Strang Crt South Freo and check out replacement part prices. I was pleasantly surprised! These guys make some really strong gear!

Getting gone!!!

Thanks for the good wrap Seaton.
What Simon said is spot on, the boom is only as strong as the weakest component and that is usually the extension tubing as it is a smaller diameter so thats where the most flex occurs.
Hydro have purposely reduced the adjustment range on our Skinny Booms for that reason, some brands have 60cm of adjustment which gives huge sail coverage but that only weakens the overall boom and decreases stiffness.
Justan, Hydro gear is available Australia World wide although it can be hard to find.
In Qld, Coloundra City Sailboards always have Hydro stock, Goodtime and Board Crazy occasionally.
If all else fails you can order direct from the factory, same price.
Talk to your local retailers and they might start stocking what you the customer wants and not just what he thinks is popular, If you don't give the retailer feedback he will never know.
