Buoyage
« on: September 13, 2011, 07:00:58 pm »

 In our club we have started using the IALA systime of Buoyage.  Why ? because it makes it more interesting and I get fed up with people asking me which way  the wind is blowing and I tell them North they say which way is north  ...Dong... The IALA systime is based on 4 Cardinal points ---North, East, South & West each with its own top mark
 and also channel buoys that are Red and Green, Entering a river or channel Red Buoy is to port Red to Red ...and the green buoy is to stb'd ...Green to Green  leaving it's the opposite way around  If you pass a north cardinal buoy --you pass to the north of it  and so on sound confusing, not really I know some really dumb stick and string merchants who learned it and even they say its easy



the photo has some buoys in it (the Red & White one is the fairway buoy

Making a north Cardinal Buoy    The buoy is a cistern float   the cage is 1.5mm wire   the mast is a bamboo dowel  The top marks are 32nd ply ( a tip the points on the top mark point to the black part of the buoy ie; North buoy points up  the buoy is yellow at the bottom and black at the top)

Nice work Jimmy.

If you find a way to get them to flash their correct sequence can you let me know.  I have made desk stand models using styrene, and they flash, but at this stage only a simple sequence.  I haven't been able to find any circuitry to replicate the true sequence.

Remember that in the USA, Canada and I think South America, the reds and greens are the other way round!

Also, and i could be wrong, when doing my theory papers (it was a long time ago) is there not an exception to the rule somewhere on the (uk) South Coast ... or was that tides ...?

Colin you are correct - N and S Amercias plus Japan and the Phillipines are in IALA area B

Kim are you thinking of the strange tides and a double high tide in and around Southampton water.

Yes, obviously you can enter the Solent from the west or via Spithead from the east. At some point you have to remember whether you are coming or going but I can't remember exactly where. But the main shipping channel is clearly buoyed and the watchword is to stay out of it unless crossing and then nip over as quick as you can, dodging behind anything large in transit.

These are the moorings we use , the counter weight keeps the slack out of the moorings so boats passing close too, don't snag it and as our buoys  stay out most if the year it allows for the rise and fall of the lakes level due to heavy rain fall or farmer Brown pumping water to water his fields

This will be the last post from me on this subject  unless anyone has any questions in which case I will do my best to answer  :-))

 RE; timing of Buoy lights
 I have seen a small horozontal wheel with contacts glued on the top of it as the wheel slowly turns it touches  a wire strip and the light flashes according to the grouping of the contacts

Excellent idea, I had not been thinking on those lines but that should work.  Thank-you.
