Bosun's chairs and climbing harnesses.

At Excel some of our MastaClimba purchasers did not have a bosun's chair or climbing harness.

This presented an opportunity for a little research.

I invited Spinlock to propose their best guess and the prospective purchaser tried it on our demo mast. He was an ex-climber and used to climbing harnesses. Although he declared he would be happy to climb in the Spinlock harness (just for fall arrest) he found it uncomfortable to sit in.

He then tried a Crewsaver chair which (for me) suffered the discomfort of two D rings aiming for my backbone. Used with a short bridle between them, this problem vanished and both he and I found it comfortable to sit in. He bought one and so did others on my recommendation and their own sampling.

The chair I use is by Compass (the German outfit I am told, not the UK chandlers by the same name;- although they get the flak!). It is most uncomfortable due mainly to the short seat.

I also have one by Lalizas which squashes my chest . It it fitted for but not with a hard seat which might improve it.

I would welcome feedback from forumites on their experiences.

The problem with the Crewsaver chair was that although it was comfortable to sit in, with an erect body, I tended to slide out although restrained by a single and, consequently, uncomfortable crutch strap.

Climbing masts seems to me to require something like a tree surgeons harness with support with the body erect and still comfortable in the sitting position.

I am told that Petzl produce a device for free-falling down waterfalls - like a padded nappy. Anyone heard of that?

The local climbing centre has had problems with dvt from harnesses. But is that a matter of correct adjustment of leg straps?

I look forward to comments.
 
I use a topclimber that seems to do the job in comfort, I have added a carabiner for another safety line.

The only time I feel slightly vulnerable in when right at the top of the mast when using the stirrups for that bit of extra height.
 
The way I feel about heights, a nappy would be a good idea! I'm afraid I get around the problem by using a mast ladder with a choice of bosuns chairs as a back-up for anyone I can con into going aloft for me. I can climb as far as the crosstrees, but somehow above that the insecurity increases exponentially.

Having done a fair bit of rock climbing (in my yoof mainly) I have both a Wild Country sit harness and a Crewsaver chair. Both are comfortable for different jobs. The main factor is how you get up the mast. If you are using your legs to 'climb' the harness is best. If you are being hauled up, like on our boat, then the chair is best. I have two mast steps at the top which I stand on but these are still okay with the chair due to the angles. For extended work at the top, the chair is by far the most comfortable. Remember the climbing harness is designed for short term use under (shock) load.
 
I'm surprised that bosuns chairs are not more like a nappy. A helicopter winchman uses a nappy like harness which of course is reasonably comfortable, very secure, light, easily stowed and allows freedom of movement.
