I'm not sure, when I got wrote paolo asking if this new saddle would have a batten like on the traverse, butterfly etc... he replied saying that he wasn't fond of the batten but was planning on having one come out with a bosun?? So not sure what the difference is?

At face value, there appears no difference between baton or bosuns.

A bosuns is a broad swing like support, that extends beyond the hips so no pressure, and has great support for the hamstrings. This creates an upright posture, and has been used in sailing, steeple jacking and other industry for a very long time.

Baton seats are a stiffened butt strap, that typically don't extend beyond the hips, are semi stiff and sit just under the backside, rather than support the hams.

Any clearer?

Its an ergonomics thing.

Baton seats are nowhere near as ergonomically efficient as a bosuns. Thats important for a climber's hips.
 
So I'm guessing what I have on my traverse is a batten? The thing is setup like a seat, it's got a stiff board that you sit on, and doesn't pinch the hips (unless it's too small for your body?) is the bosun much wider than the batten, and wouldn't that create a problem moving about the tree.

Could you give an example of a saddle that is on the market now that has a bosun??

Thanks!

jp,

I have used both the traverse and cresto skybelt(without shoulder strap attachment) KS22 on Treespotters link with photos in his last post to you, scroll down the page.

They are very similar harnesses, both have 2 sliding front Ds and the hard seat.

I found the skybelt to be very comfortable, more so than the traverse.
The skybelt has better tool attachment points.

I found the traverse was digging in at my hip bones at the sides. Where the side Ds are.

My first skybelt's hard seat broke after 1 year, I continued stupidly to use it. Propbably not good for my hips.

The one I use now, the seat has been great, no problem I am 6ft3in and I have found the skybelt to be the only harness for me so far.

I would still like to try the Komet Dragonfly

Other bosun seat type harnesses - the truly bizarre Petzl Nahavo Boss

I have only seen one treeclimber use this harness, he liked it.

I think they should have called it 'THE BIG BOSS'

Looks like you'd have to take half an hour to put the this thing on! then another half hour to set all the straps!

Look up batten in Wiktionary, the free dictionary.This article is about a piece of construction material. For the English academic administrator, see Joseph Batten.
For the English composer, see Adrian Batten.
A batten is a thin strip of solid material (usually wood). Battens are used for various purposes in various fields. In cabinetry battens may be used to strengthen panels made up of multiple boards, as in a batten door, or to cover joins. In building construction, battens are fixed at right angles to the trusses or rafters of a roof to provide a fixing point for roofing sheet or roof tiles. In sailing, battens are long, thin strips (usually fiberglass, or some similar material, nowadays, but historically wooden) used to support the roach of a sail. In stagecraft, a batten or rail is a long pipe, usually metal, affixed to the ceiling or fly system in a theater.

A bosun's chair, in use by an actual bosun, re-tarring a section of a backstay on the Prince William after making a minor repair.A bosun's chair is a device used to suspend a person from a rope in order to perform work aloft. It is distinguished from a climbing harness by the inclusion of a more or less rigid seat, providing more comfort than even the best-padded straps for long-term use. In exchange, the bosun's chair does not allow the freedom of movement necessary for climbing, and the occupant is generally hoisted or lowered into place using the rope alone.

Some bosun's chairs consist of little more than a short plank and a suitable set of ropes to suspend it from; these are usually used with a separate harness in case the user should slip off the plank. Other bosun's chairs, particularly the type commonly carried on yachts for masthead repair, incorporate more straps so that the wearer cannot fall out, though they still include a rigid or semi-rigid seat.

As well as on ships and boats where they originated, bosun's chairs are also used for working at height on buildings and other structures

I think I have permenant bruising on my hips from the traverse, that's the only real complaint with the saddle is the lack of padding on the back support, other than that it's solid.

But I'm waiting for Paolo to come out with this bosun treeflex...

I just got a Dragonfly to replace my Traverse. The D-fly sits in a strange position, one feels like they are being pushed to an upside down position. I lengthened the distance from the seat to the bridge with some loop runners and it is now much more comfortable

I am waiting for more feedback on the Flex
 
With the Cresto Skybelt most of your weight is on the bosuns seat, which is great if your cabling or working in an area with no footholds.

Big drawback is the inabilty to position your feet far apart. When doing big pruning jobs and takedowns.

The Dragonfly has a smaller batten than the traverse and the skybelt, was most of your weight placed on the batten or the back support before you made the modifications to the Dragonfly? and is the Dragonfly anything like the Butterfly 1 which I found to be like sitting on razor blades!
 
Weight was distrubted evenly, so the harness would actually want you to be in a horizontal position

Unlike the traverse you cannot adjust the position of the seat, which is why I had to add the loop runners.

I never owned or tried a BI so I don't know how it compares. Compared to my Traverse the D-fly is lighter and now is more comfy. I could actually wear it without buckling the leg straps and the seat would still be where I need it to be. Even with them buckled I can still get the far reach with my legs without a problem.
 
Just to confirm I will be at Capel Manor College open day on 27th & 28th April, holding ergonomic SRT climbing demos if you want advice on how to set up a simple safe system for ascent.

It will also be a good opportunity to try different sizes of TreeFlex and get your personal fit 'dialled in' at the Safety technology stand. Any questions can be answered in person about the ergonomic climbing message and the TreeFlex product.

I look forward to meeting some 'buzzers', don't be shy!

I am looking forward to reading some reviews of this saddle.
Paolo, is your web site down? Also can you encourage the folks who have this saddle to post here at TreeBuzz RE: their thoughts and experiances with the saddle?
