Here is the video i put together for the new Severne Lockjaw boom head
time will tell - these things are gonna sell like hotcakes when the booms hit shelves
Aluminium booms will be in OZ end of This month
Enigma Wave Carbon end of October
Slalom and Formula / Race Kick are a bit delayed unfortunately
I am very excited to see a genuine step up in boom performance hitting the market.
There are going to be lots of VERY happy windsurfers out there.
I think i,ve missed something. I didn,t see anything new????
Been using booms for at lease 4 yrs that don,t need an adapter to go from STD to RMD and no point loading. They do look nice though
I dont know what is so revolutionary about the boom head
this one also uses grip and contact, has a pivoting attatchment to stop point loading and comes with an adapter so you dont need to swap boom heads in the the cross over size sails that use sdm or rdm masts.
On the point loading front
- if you have a larger surface area on the boom to mast interface
that moulds to how the mast is shaped - with a longer vertical contact area, increased area overall - and a taper in the mast to boom contact area
then you get a much more mast friendly product - that grips to the mast (due to the increased contact area) - so you dont have to run high tensions on the clamp -
moderate tension and the boom will stay there all day long
noise is probably where the rear bit around the mast overlaps the front bit as it is tensioned and it groans a bit as they rub together? Sounds like it is broken but it isn't...
Looks like the current clamp system they use which is rubbish it just clamps the back and front . My inigma boom moves more in the clamp than my cheap prolimit .
Its actually a Chinook head developed in conjuction with Aeron as far as I'm aware. You will see them on a lot of brands booms. Probably because they work really well.

- the ergonomics and geometry of the rope to sleeve action are just so nice - its just super easy to pop on to the mast and attach - takes about 3 seconds to pop on
I struggle when i go back to the old generic heads now - and the loads that the current standard generic designs run just seem super excessive by comparison - especially on SDM masts - which i have actually seen broken by riders running firm tensions and transferring point loads onto the mast wall
i welcome the skepticism
- yes -i agree its definitely more evolutionary refinement than revolution - if you are curious at all check one out in a shop over summer and you will get some insight into how well finished, engineered, ergonomic and mast friendly these are.
The head also easily swivels 90 degrees into low profile travel mode - which is pretty spiffy!
Barn - you have bent a M6 bolt thru a boom head before? When it runs through a block of FRP so it is supported along most of its length (same as Chinook/Autima/Severne system above) ???? 
Without fk'ing the rest of said boom?
Revolutionary is the north boom with the iFront boom end which allows movement and even that has been out for while...
So real revolution is get rid of the dam rope
I like the big thick rubber knobbles to protect the board, next time I want to bounce the boom head on my board I will remember to use a Severne boom head. Until I get one though I will just keep rigging it so it clears the board by a good 10cm at either end.
Looks exactly the same as an old prolimit I had with such a chunky head.
Dont know how good these Streamlined ones were but they were definitely revolutionary.
What about the old Peter Cabrinha double-head boom - anyone remember them?
Another bolt-bender here...also don't understand all the noise about the boom head in the vid - looks pretty, but basically the same as other boom heads. I was expecting some electronic self-tightening gadget, or adjustable height on-the-fly type setup.
The integrated bumpers are much prettier / lighter / less time consuming than having some daggy boom diaper thing hanging off the front .
