exp with mob-alerts and direction finders ?
 

Hi all,

Anyone here familiar with mob-alerts and direction finders?
I saw this one:
http://www.landfallnavigation.com/seamarshall.html
I'd like to know if the (rather affordable) handheld will do the job
in heavy weather. I have doubts re the question if the waveheight
forces me to place an antenna up in the mast for succesfull
retrieval. Short periods of reception when the unlucky crewmember is
on the top of the waves could suffice.
I'll ask the manufacturer but for the obvious reason I value
cruisers experiences many times more.

Any experiences / other products / suggestions ?

Anyone ever did a Mob-operation in real life? What method did you
use / what did you learn the hard way?
When I read these magazines I tend to think they are about mob
situations in rather calm weather.

Fair winds, Len.

For directional indication, the $3K base needs three antennae, up high
for best results, on deck for best accuracy.

MOB with dismasting is a possibility.

User battery life? Change every month? Waterproof battery door, or
inductive recharger rack at companionway? Night light function?
Includes a whistle?

I have been a MOB and I lost an expensive floating hat in daytime
whitecaps, once. It's easy. If far at sea, I would even like an
aluminised retro reflective hologram hydrogen balloon on a string with
a fishing kit, water still and umberella. Any proper 'brolly for a
sailor includes a lifejacket with integral harness, anyway. Any of the
soon to be mandatory sailing helmets should include a schnorkel and
breath still, if nothing more. Some kind of grease to minimise skin
osmosis and chase sharks might also help.

Might not this neck lanyard float away from a snoozing popeye? Maybe
the sailing helmet would be large enough (with chinstrap snug) to
prevent it's loss. How about a sonic alarm to remind user to do up his
chinstraps?

Cost benefit? How better to spend the money?

How to get the crew believing that a battery toy is better than a
lifejacket, lanyard and survival kit including a whistle and an
umberella. What kind of discipline is that, Darwinistic?

No wonder the ecology is getting screwed.
