Mostly land based things. Can you give a few examples?

I found this one,

looks to be both surfing sand swimming...

There are those that say yes to a formal proposal, others nay.

You may have noticed my Hills Hoist thing.. I raised it here to see what 
reaction I got and to seek ideas. I have now raised it on the tagging 
group for more of an international view and will raise it on the russian 
wiki page on the 'umbrella' tag.

I would think you may get some feed back here to start with.. then raise 
it on the talk page

As the break would be a water feature I'd use a water tag 
waterway=surf_break ??? That could be a way where the break first occurs 
.. possibly sub tags such as break=left/right/* This would be the 
physical feature for use with sport=surfing...

Just my idea.. you may have more/different?

The surf break may be visible on some of the satellite imagery. Mapbox 
off Tamarama Beach, Sydney looks large.
