Hi Augustin,
Oh no, far away from there (Quiz for you: a nice little town where some
Mercedes Benz are built).
Right, but i didn't worry about this, since having always a chart onboard
:)
The other side is, that i remember the categories of lights described as
somewhat like "usual used for", so i'll never assume that it's a must.
Ok, sitting in my well heated room and studying the literature, looking
through the rain dropped window, having a beer ... i'll get it sooner or
later :)
Sure? The INT1 chart said chart datum, i remembered it this way, only the
chart datum itself will depend on the region <?> .
Oops, never heared about that. Just the period is defined as the length of
one entire (over all) signal cycle (i.e from the one beginning to the next).
Hmmm :) prehaps i should remark that the people here * (or some of them)
like to have everything ensured. So you have to have a licence to sail, and
to get it you need tons of paper to know. One if the first for offshore is
that INT1 chart.
The other hand is that there are anyway lots of people on the water where
you must assume that they have never heared about anything.
* i'll not sell out the county :)
Ok, since i have seen the first snow today, i'll try again.
Isophase (on time = off time), period 2s.
Alternating (2colors).
Had not enough red color to paint the whole, forgot the numbers :)
Had no green color, took black instead :)
Ok, never seen nor heard about them, perhaps they'll be country specific?
Btw. yours port hand lateral lights are green? Ours are red... is a little
confusing while first time sailing trough.
Ah, fine, hope to have no more probs with the snow :)
The same myself :)
Ciao
Ralf
