Summary
Static Testing
Test Setup
Each
harness was donned both with and without foul weather gear. The time to
don was recorded, as was the ease of donning. The normal wearing comfort
and apparent weight of the harness, and whether a Type III PFD
interfered with the harness was evaluated. We donned each harness and
hoisted ourselves on a dinghy lift, and evaluated the harness for
comfort, pinch points, breathing.
Test Results
General Comments on the inflatable harnesses:
All the harnesses appeared well built, and were fairly easy to don
because the straps don't easily tangle. They all rated in the middle for
perceived weight, because they have the added burden of the inflation
mechanism and bladder. They all passed the magnetic test (none were able
to affect the compass, even when placed right next to it). The
workmanship was excellent for models examined. They were all
uncomfortable under load, some being slightly better or worse than
others were. The average time to don an inflatable was approximately 5-8
seconds.
General Comments on the standard harnesses:
The standard harnesses varied more in their makeup than the inflatables.
The harnesses that included some sort of a vest in the harness were
easiest to put on (Raudaschl and Survival Technologies Deck Pro), and
the harness that didn't have a rib strap (Lirakis) was easier to put on
than those that did. Time to don the harnesses ranged from about 5
seconds to 45 seconds (when wearing foul weather gear and also putting
it on backwards). Standard harnesses were perceived as lighter weight
than the inflatable harnesses, because they didn't have the added weight
of the inflation bladder. We found that most of the harnesses were
uncomfortable under load, the exception being the Raudaschl harness and
the industrial and rock climbing harnesses. A crotch strap helps take
the load off your ribs and increases the comfort level. Because of the
location of the attachment rings at approximately mid-sternum, wearing a
PFD over the harness will mean that the tether will have to snake out
over the PFD, and it will not allow easy access to the attachment
shackle. The main shortcoming of almost all products were instructions
for use and care, the exceptions being the inflatable harnesses which
must meet UL and Coast Guard requirements, and the Crewsaver and Holland
Yacht Equipment harnesses. We did find that the Jim Buoy harness was
slightly magnetic, which could cause compass problems.
Comments specific to the comfort of the harnesses for women:
It is very difficult to make general comments on the comfort for women.
Some harnesses marketed specifically toward women were found
uncomfortable under load, notably the Survival Technologies Deck Pro.
Also, some women preferred having the rib strap lower on the back, while
others liked it at armpit level. Some liked the shoulder straps close to
the neck (like the West Marine Securite), while others liked them
farther out (like a standard unisex harness). Our recommendation would
be to try the harness on at a chandlery and put a substantial load on
the harness, parallel to the spine, to see if there might be any
discomfort. The two most comfortable harnesses were the Raudaschl, and a
rock climbing harness worn in combination with a chest harness.
