You'd like to think so but alas it doesn't always work like that. I was soloing alone ( tautology much?) at Portland one choppy day when a few other groups showed up. One guy fell off a harder route and swam about a bit. After a long time (10-20 minutes I guess) I realised he wasn't coming out. Every time he approached the exit point he'd sink into a wave trough, see the next peak towering above him, shit himself and swim back out to tread water for a while. His mates did f'ck all as he got weaker and weaker.
In the end I threw him the life jacket that I had, rigged an abseil and went down for him...
Was deeply scary trying to rig the rope so that I'd be just in reach of him at max wave amplitude but not battered.
We did a few false starts then eventually we managed to clutch each other and hold on for grim death as the wave receded. Then we sorted something to get him up the rope.
A real lesson to us all about how dangerous the conditions were that day, but at least I'd gone into it knowing that I was on my own if it went wrong. This bloke's mates clearly weren't...
