Bumper boats!

I've always been the biggest fan of bumper cars - it's such a pity that most funfairs don't allow people over the age of 10 or so to play on them, though. Maybe they'll let me have a go on these cool bumper boats instead?

The Enseleni (at the back) was built in Durban in 2001 and has a bollard pull of 50 tons, while the Pinotage (just in front of the Enseleni) was built way back in 1980 and has a bollard pull of 43 tons. Bollard pull is basically an indication of how strong a tug is and how much force it can exert on another vessel (although my research tells me that it is a little more complicated than that).

So just remember, if you ever get invited to play bumper boats, make sure you get the boat with the greatest bollard pull.
