Hello,

I am looking at buying an ISo and I need to know what the Air Draft is, so that i can calculate how far upstream I can get on my local river.

Thanks

Simon

You've confused me - but that isn't a difficult thing to do.

air draft is basically the height of the top of the mast once the boat is in the water. I dont know the actual full dimesnions of the boat and cant seem to find them anyway.

Does that make it a bit clearer.

Cheers

Simon

The length of the mast is 7.13 meters.

The mast sits in the boat and is near enough water level.

Don't forget to allow for Burgee length, how far the boat sinks in the water when people are in the boat, the height of chop / waves.
