i got a full RYA dinghy
Instructors certs - far more comprehensive than a day skipper or even a coastal skipper.
the RYA Level 3 dinghy
cert sits between a day skipper and a coastal skipper and a level 5 is above a coastal skipper and the instructors cert is not far off a coastal ym in terms of whats covered.
i have always prefered my crews to have a dinghy sailing background - its not until you've learnt to master a dinghy that everything sinks in properly JMO.
a dayskippers cert to me just means that you've aware of whats what and the practical just means you know where stuff goes - which is RYA level 2 dinghy. level 2 dinghy covers charts
and reading of charts
and winds and tides.
the certs that i really like seeing are the practical ones - you can drill theory forever but practical that only gets drilled in real time. i have some crew doing practical courses on board now and again and even though i'm in racetrack mode it challenges them to do their sums and fast and i think that they get a lot more out of it too - you're aiming for a mark for a in/out going tide and all sorts of underwater features - most club races are inshore affairs so challenge everyone --- offshore
its a lot easier cos there's more room to make a mistake whereas inshore particularly with a boat like mine there's very little room and this is where the RYA won out for me.
