I'm selling my Chinook carbon RDG because it's floppier than a wet noodle. But I love the tiny grip size. I also have the Goya super skinny 150-200 and that boom is significantly stiffer than the chinook RDG, but it's also a slightly larger diameter grip size. Is the Duotone Mega Slim any stiffer than the Chinook.

Skinny = bendy

Not a fan. The moderate increase in comfort is not worth the massive bendy noodle effect for me.

Little guy with diminishing skills. 73 kg., 73 years old.
Love bendy alu booms. All last more than a handful of years. Think 15 year old standard alu Chinook half extended is too stiff.
Found my 30 year old, used close to 200 days, old Euro boom in Puerto Rico, used it 12 days there, and was thinking of bringing it back to San Francisco with me. American said..."no".
I sailed it all in small surf and onshore wind with 5.5. Wind 10-20.

Oh....always had carbon booms since 1993.
For racing and speed, they were good.
For waves, they place more stress on masts, and I preferred sdm for float.
Past 20 years no comps, only rec sailing. I like using the smallest sail for anyone my weight, so don't need stiff booms.
For windsurfing in typical 14-21 knot breeze, 5-6 is my choice.
I can hold my slalom sails in 7.8 sizing easily at that windspeed. A 7.0 is my choice.
I typically sail with guys who use 1-2 meters bigger sails and full on slalom boards. Most can jibe 95%.
I am always top 90% for speed and planing thru jibes out of 30 rec shortboarders.

Try a highend one like the Duotone or Pryde, pricey but super stiff. The Chinook RDG is notorious for not being rigid enough, I have the Duotone mega slim and it's just night and day. Now I'm not a fan of the shape of the curve (I prefer the rounder designs like the NP) but that's another thing

They still bend more, regardless of how premium they are....... its a fact of life that for same weight a wider tube bends less.

As to the strength - I dunno if skinner is stronger but I know the only carbon booms I've broken have been the skinnies, I'm back up to 28 or 29mm again with no issues - Simmer Blackline (5y/o ish) and similar age North Platinum.

Unfortunately not everyone is the same and some people can't sail more than 10 mins with standard diameter booms.

Which would you choose:
Standard diameter boom = 10 mins on water, then rest time on beach due to forearm pump
RDM boom = 3 hours on water

Suggest you also consider booms with a v-grip.

I tested a few booms and a v-grip with an extra 1mm at say 25mm ... result is that a 25mm v-grip is more comfortable than a 24mm normal diameter.

AL360 is the way to go.

Might need to look at your technique Jake

Those "v" booms are easier to hold sans harness.
But, for some peeps like me, they really point load and cause early callous to blister to ripped hands.
I got rid of my last Fleetwood carbon oval grip 10 years ago.
Prefer round and slightly flexy at old age.

I've had,, severne, chinook rdg carbon booms.
My 2 cents as a larger wave sailor, 90/95 kg, using big sails 5.5/5.8 in light and gusty conditions and powerful waves.
Ive found them stiff, great quality, the chinook has an overly complicated grip all the lettering, didn't last, re gripped after 2 season, still going strong. The rear end could be wider for bagging out sails a bit for float and ride.
The carbon is stiff, light, and great quality, made in USA by chinook. Not a China by third party and re branded.The severne grip is excellent from new. The clamp head needed re shimming, I think they all do, sand between carbon and plastic.
Ive seen the duotone top end one and it looks awesome, it's light, slim and expensive.
Goya rdg also excellent, I believe they are a generic boom, banded for Goya but could be wrong.
Another to consider if you don't want super slim, is streamline carbon. Made in house, alloy clamp. Super strong and stiff. No loop and go on boom end though.
