Now were talking!

Right!
No joints, no wearing or corrosion, no travelling backwards or forwards -just up & down. An almost perfectly linear vertical travel of 150mm.

Regading the nail clipping anxiety: Have no fear!
The holes in the front bracket of the mech is the last place anyone would stick their fingers, except for maybe in the propellars.
As long as there is vertikal movement there will always be a theoretical risk of getting some part of your body hit by the moving parts.
In order to get your fingers into these holes though, you would have to move your knees and legs out of the way and bend forward.

There is another solution as well. The standard model (Biscaya)has a longer "skirt". Se Picts.

Dear, Dr. Ullmann!
The fabric on the seat looks like neopren, the same as what wetsuits are made of. When using wetsuits it is always very important to rince and dry them after use. If not done propperly, the wetsuit will not last very long. Knowing that the fabric on the Ullamann-seat is stuck to the seat and that the fabric will be soced in salt water, I am wondering what will happen with the fabric on the seat.
I am asking because I just had two seats mounted in my new boat.

Dr Ullman,

Are the "linkages" carbon fibre plates clamped at each end? I like the idea...as you say, no pivots to corrode etc.

Cheers

Tim

Upholstery on Ullman Jockey Seats

The first boat, that was equipped with Ullman Jockey seats, is operated by SSRS, the Swedish Sea Rescue Institution, since 1993. They called a couple of monts ago because the neoprene covers were worn out.
We expect them to last long, but we have to assume that they do not last for ever. When they wear out, the covers can be replaced.

We had some seats with blue upholstery on the Zodiac CZ7. Under the sun of Florida the color bleached already the first season.
Lab test witout salt did not result in bleaching.
It is probably a good idea to rinse out the salt to prevent fading.
Still there is no fabric that will not tend to fade over the years. Black is far better when it comes to not fading.
We also produce cover bags to put over the seats, which we recommend for tropical latitudes and of course offer to all customers who whish to keep the seats from aging.
Remeber the covers people used to put over scooters and MCs way back.

Yes.
This means that thy will flex into an S- shape. We have measured up to 18g vertical impact on the human body onboard RIBs. The forces acting on the structures are enormous. That is one good reason to keep the mechanics solid and simple. Salt Corrosion and Wear are others.

(I just answered to a question from Fjordrafting about seat covers, but the reply ended up here, instead of next to the question. Ill have to figure this out....)

Ullman Jockey Seats

Call Henrik at +46 31 708 26 00. He is better updated than myself.
We are tooling up now,to increase production capacity, as the demand suddenly has started to rise.

There are different models and different suspensions.
Excallibur and 200Hp sounds like you should look att XLT mech (extra long trvel)

Henks email is: Henrik.Andersson@ullmans.com
