Boat Comps and PFDs

Following on from recent discussion, and to clarify the clubs position.....

- It is a compulsory requirement that each SAI-SAC Member wishing to take part in a Boat Comp/Meet wear a suitable PFD at all times including transfer to and from the vessel.

- PFD must be worn properly at all times. No flapping jackets, no discarded flotation suit jackets etc.

- PFD should not be removed at any stage whilst on board the vessel other than for changing clothes/toilet etc.

- It is your responsibility to provide yourself with a suitable PFD, there may be "spares" which can be provided by another club member but there supply is in no way guaranteed and you are advised to check and confirm first.

- Failure to comply with the above will result in you being disqualified.

60 to 100 quid will buy you a decent Auto/Manual gas operated life jacket that will serve you well either from the rocks or wading beaches at night also. Aside from a few quid to replace the cylinder each season thats it as far as expense goes.

This is not a new rule, just one that will in the future be enforced. We do not wish to exclude anyone or have to refuse access to a boat on these grounds. If you are a newbie to the boat scene and dont have a jacket, post up PRIOR to the comp and we will see what we can do regards organising you one.

Good move. I was thinking of getting a life jacket, even for use on rocky marks.

I was thinking of an auto inflating one. Could someone explain what the difference between one with a harness and one without?

Also, I was thinking of getting one from the UK where they seem to be better value. (I say "better value" rather than "cheaper" because I'd like it to actually work). Maybe something like this:

Any thoughts?

I guess it would need to be delivered without the CO2 cylinder, which I'd pick up here.

Hi lads,

I got my 170N jacket from marineparts in swords for 65 euro.
How much is your life worth? :wink:

I have 4 on the boat so anytime I am in for a comp just ask and I will bring at least 3 for others to use no problem. :lol:

170n, what weight do you have to be under for these to keep you afloat?

CLEVER THINKING

Clever thinking

its so easy for simple accidents to happen even on a day that is flat calm

170n is 170 kg so pud have to be pretty heavy to sink

50N = 11lbs buoyancy

100N = 23lbs buoyancy

150N = 33lbs buoyancy

170N = 37lbs buoyancy

275N = 62lbs buoyancy

Archimedes proved alot of my theories wrong :? :? :?

i was going by this
http://www.crew-safe.co.uk/acatalog/CE_ ... tings.html

now dont get me wrong..

i wasnt saying that 170N = 37lbs buoyancy so you have to be less or equal to 37lbs for it to keep you afloat.. i was stating that that is how much buoyancy pressure it gives

Nope
gravitaional constant is 9.81
1 kg is approx 10 N

and before I'm corrected, 9.81 is small g, the earth's gravitaional constatnt, not Big G, the universal constant.

Hello teacher.
Most of them have a harness of sorts but the difference is if you get one with a proper harness it can be used to attach a line to it in the event that you have to be lifted from the water by the R.N.L.I. or coastguard helicopter.

Sounds like I might as well have it as not. I assume it won't add too much to the bulk?

Hey Paul,

Is there any specific type/make of PFD which would be preferred over another.
Also in relation to size - would the 170N provide enough bouyancy for a (ahem.. :oops: ) larger person. I'm not the smallest of people - would i need to move up to the 200+ N size??

John.
