One turn penalties

I know that in some competitions (eg match racing) the 'two turn' penalty has been replaced by a 'one turn' penalty. There is even a  'prescription' to the US Sailing version of the RRS that gives this option. Has anybody come across this at club level, and if so is it a good or bad thing? As one who sails a multihull in a dinghy fleet, I would welcome it!

On the odd occassion where I know I've made a mistake and infringed the rules, I'm happy to do two turns and get a finish. Often such a finishing position would be OK for series points.
I think a one turn penalty might encourage people to take a turn rather than fight their corner in a protest when they 'know' they are right, as you can make yourself bulletproof, while losing less ground than the boat you have just tangled with. That might actually lead to less clarity of the rules?

Maybe place penalties?

Most of the time what I'd like to see from other people is just an admission they were wrong, unless something significant hangs on the result, an apology is more important than a penalty.

What about they way they have been doing it in the ac series? Where they have to slow right down and they are not allowed to carry on till they have cleared the other boat.

Not really - keep taking turns until you are behind the boat you fouled - simple really. If you don't the penalty is not appropriate and the jury can disqualify you.
