Sitting in a traditional seat puts your
spine into a C-shape. This is the worst
position for the spine to be in when
exposed to a vertical impact. Head
jolts can cause whiplash-like distortion
injuries and disk ruptures in the neck.
guaranteed or even claimed to be compliant with the EU directive. There
is a caveat, Ullman’s claims are that the jockey seating configurations are
currently the closest thing to EU compliance on the market.
With the EU struggling to legislate and ending up in a red tape fog,
Ullman is exempt from the EU regulation in its purest form and indeed I
assume, so must all other players in the market.
Ullman’s other concern was ‘bottoming out’ and Carl Ullman clarified
for me, “Bottoming out means that the suspension reaches the end of
its mechanical stroke. Some suspensions are prone to bottoming out,
which can significantly amplify the peak acceleration, and they would
be better off in seats without suspension.”
Let me explain ‘peak acceleration’ and back to Sir Isaac Newton, it’s
not just the mass of a human body it is the product of the force that our
bodies are accelerated at, that makes us heavier. Too much force and
it hurts and even dangerous on impact with a wave!
There is one other thing on Ullman’s website that I took attention to
which was about posture. Carl’s father, a Doctor Johan Ullman being a
professional inventor as well as specialist in anaesthesiology and intensive
care in occupational medicine. His affiliation is with the University of
Stockholm and given that sphere of influence embarked on extensive
SHOCKWAVE
Many types of leisure boats will be able to accommodate
their recreational Sentinel suspension bases. The most
common install method is mounting to a riser box, or to a
short pedestal. The suspension base is 220mm tall. Provided
you have 220mm clearance below your seat, you should
be able to fit the Sentinel suspension base to your boat. For
the recreational market the mid-back is by far most popular,
with the S5 Sentinel suspension the most popular choice
for the majority of recreational boats. Performance, size and
cost are optimised for this market. That said, some of their
professional seats that were initially designed for the military
have been well received by a segment of the recreational
market that value performance, luxury and function, over cost.

research into how our bodies react to high impact at sea in whatever
guise. He stated, “Sitting in a traditional seat always puts your spine
into a C-shape. This is the worst position for the spine to be in when
exposed to a vertical impact. There is risk for head jolts. Head jolts can
cause whiplash-like distortion injuries and disk ruptures in the neck.”
With the above in mind, seats have been remoulded, redesigned and
logistical design has been improved, though bear in mind, this was the
journey with military, emergency and municipal services that came before
our recreational market.
Other major contenders in the market, their take on how they have
successfully engaged with the market is interesting, worthy of consideration
and warrants a visit to their websites for the fuller picture.
My conversations around the world started with Shockwave seating
and mitigation systems. 24 years in existence, Shockwave is Canadian
based and one whose roots still remain in special military forces around
the world, supplying Sentinel bases and a range of seating to boot.
That said their unique claim is all that is required is a 220 mm clearance
gap to fit the base beneath a seat. The absorption process is principally
based on air/sprung cushioning and the system can be installed within a
day. The Sentinel is equipped with a 100mm travel FOX Float H2O shock
