Today our team split up.
Ulf went to attend the medical seminar, while Peter Davis, Dan and Philip went to the in-water life-raft session.
Both sessions were very well run and contained a lot of valuable information.
For example, did you know that if you jumped with your regular street into 50F / 10C water without a lifevest, you would make it for about 15min.
If you jumped in the same water with the same clothes but added a lifevest, you likely survive for about 4hrs…
In the first scenario you’d drown as the body struggles to stay afloat, while in the second hypothermia would result in cardiac arrest.
as the goal is to stay alive for as long as possible, trying to keep warm is the key.
In addition to wearing a life-vest,
– closing sleeves and pants to avoid getting newer colder water into the foul-weather gear
– keeping boots on (they do not make your drown as they are filled with water already and are mostly positively buoyant)
– making sure to keep a warm hat in your pockets or wear it
– wearing the hood of your jacket over the life-vest (as you will not get it once the vest is inflated)
– staying calm (do not swim or exercise to generate blood flow etc) and keep knees and arms close to the body (use your tether to support your legs for longer periods of time)
– building floats with other crew members to reduce exposure to colder water (stay together with the group in general, use tethers and hold on to each other)
or good options to extend the time in the water alive.
Other lessons learned:
– stay on the boat for as long as possible
– prepare departure very well
– ensure raft is tied to something solid on the boat, such as the mast (not stanchions)
– take as much with you as possible
– bring as much water as physically possible (ensure water containers are always full and ready to go)
– assign tasks to all crew as to what to bring to the raft
– have a plan to get ditch bags etc safely to the raft
– take head count before departure and check crew’s condition (physical and mental)
– strongest person goes first and gets into the raft to help all others getting in
– administer seasickness medication as soon as all are on board
– tie all equipment to the raft to not lose anything in case of capsize etc
– be very careful with flares, use only downwind
– get the water out as fast as possible
– hygiene is very important
– keep wearing life-vests inside raft (relieve air-pressure to create space and make wearing them more comfortable)
– don’t forget your epirb on the boat (keep in ditch bag when sailing to not forget)
