hi

jeff cote here with votingtechtalk.com

so we've got a question from a fellow

boater

about ais ais stands for automatic

identification system a protocol

by which boat to boat transmit

not only their boat location their speed

on ground

their course on ground and it's used for

collision avoidance but also for

identifying boats

that are in the vicinity of your boat

and this does not

require any sort of land station this is

ship to ship

which is great so it would work in the

middle of the ocean it would work

as remote a place as it can be because

it's actually boat to boat

so all right so the question is the fog

we're talking about ais here

i've been looking at the bng combined

vhf and ais

transceiver would you recommend going

for a combined device

like that or rather recommend a separate

vhf and ais device

that's a good question and a tough

question actually because

i don't think there's a simple answer it

really depends

uh generally i do like as a rule of

thumb

i do like separation of devices i think

that's a good idea

and it's it's not a bad idea to not have

all your eggs in one basket

right so that's one philosophy right

redundancy right so have an ais

sort of transponder and then have a vhf

radio that's one way of looking at it

another way of looking at is hey

jeff i'm going to be replacing my vhf

radio because it's bad

and instead of just replacing the vhf

radio why don't i actually replace it

with a combo unit

hey jeff another option would be i've

got no place for a black box i just

don't

so maybe my radio could be the one

device that does both hey that's a good

reason

and then the other thing too that you

would keep in your mind is well okay

well what kind of voting are you going

to do are you going to be doing boating

in places where there's a lot of sort of

navigational challenges

based on you know i can imagine boaters

that are going in

really busy shipping lanes right some of

us live in

areas where the port is rather active

and there's a lot of marine traffic

going around and that might be like okay

well in that case maybe my eis is really

really really important and i want to

have separation

so that'd be one factor to consider most

of the time

what we end up doing and i said most of

the time because every rule has an

exception we end up doing a dedicated

vhf

probably with a built-in gps probably

big fan of that so that the dsc

functionality on the radio works sort of

the 911 feature of the radio would work

and then we'll go with a black box ais

a transponder which has a transmit and

receive capability

and will divide and conquer and i do

that because

you know i'm always sort of worried i'm

always

thinking what happens if you lose one

then you lose the other

so i would keep them separate in many

cases

but there are exceptions to those cases

and i gave a few of those exceptions

that would apply

and yeah that's how i would go about it

so that's a good question and not an

easy one

you got to think about pros and cons on

that one it's not black and white
