I rest my case on posters posting crap simply because they have access to a keyboard that is connected to the internet.Screw the prebend this isn't race day, and so what if the mast gets stuck with or without the sail on it. If you don't know the technique of getting the mast unstuck your in trouble either way. I call it all bullshit. He's just startin out guys. He will have much less of a chance capsizing with a smaller sailplan. He will learn many of the Idiosyncrasies of the boat. Then after building confidence on light air days try out the 5 oh sails until he gets up to speed on it. And so what if there is no 5 oh fleet in capetown. He asked about the 5 oh and the 420, not racing one design.
Having a boat with sails that don't go to the top of the rig is simply asking for trouble if you capsize. The mast gets stuck in the mud easier and is more likely to break.
There is no active 505 fleet in Cape Town, and there never has been. Most of them are in Gauteng where the wind is a lot lighter.
Current peak wind speed as we speak is just shy of 30 knots at my lake.
thats an awful idea. dinghy masts carry a whole lot more prebend relative to the height of the mast than keelboats, and short hoist is just going to cause hell to the sailshape with the different luff curves. At best it wont be efficient or fast, at worst it'll make it harder to learn how to make sails do you what you need them to do or even create more drag/power than forward moment...
Go with the 5 oh and start out with the 420 sails on it. You don't have to use all the control lines on the boat just cause they are there. Its more roomy than the 420 and once you get used to it, you can power it up with the 5 oh sails etc.

Dinghy sailing, and good red wine!
