I've used a light lanyard with a Patima housing for the C5050, as well as with an Ikelite housing and a Sony HC1. If that won't hold up, you're probably not going to be getting decent pictures on a beach dive anyway; that's the point where you either don't take the camera if you've just gotta dive, or don't dive at all. Both the Patima aluminum with attached strobe and the Ikelite housing for the HC1 weigh in at 10+ lbs, a lot more than the olympus housing. I have not taken the Ikelite through the surf yet, but the Patima has made it through So. Cal surf several times. Bear in mind that some people would consider me crazy. I've also taken Canon and Nikon PnS housings through the surf in a BCD pocket several times. You're guaranteed not to lose it unless you lose your BCD, and I've never had one flood. Bottom line - have insurance, and a lot of good karma built up.
