i m not sure the aids help so much. Although not 100pct foolproof , you can build up some logic. One stern light or two lights, tells the length, then you can get the aspect, work out power or sail. Then you re half way there. Common ones are going to be pilot,dredging,aground etc. Who can remeber some of the catch phrases? balls in a line= a total balls up=run aground etc. Wahst the one about lights and pilot?
Confess I d need to revise them again, but just the RYA YM booklet is enough. I reckon you only need to learn about half a dozen "odd" ones- the rest you can deduce.
I can try to find my old notes if i ve still got them, but its not a case of having to memorize dozens of variations in fact. And for one more mark, I d not bother with some of them-think even the RYA recognise the exam should have some practical purposes!
I have found the flash cards very helpfull. they can be used to ask a question from both directions, i.e. what lights should be shown by a vessel constrained by draft?, and also what do 3 vertical reds mean? You can also lay them out to sort out the patterns, similarities and differences to help make sence of it all.
My 9 year old daughter was wandering around the Kelvin Hughes stand at the Southampton Boat Show in 2003 when one of the owners/developers caught her attention and gave her a demo. We were there for about half an hour and bought it on the spot. It really is very good.
