I think it has to be specially textured for the job, rather than just be put on with a trowel in the absence of a paintbrush!

Now, depending upon what you drink, weeing down the centreboard case could be seen as releasing a substance to improve laminer flow.

Really does it say that? Does my bad paint increase flow? Very hard to enforce that rule.

If my memory serves me right RRS 53 was designed to prohibit some stuff that you gunged on before the day's sailing, and which slowly dissolved/melted/something or another into the water over the day.
I'm quite sure any kind of normal wax or teflon polish is just fine.

That dirt on the boat will have at least as negative effect as anything else.

Boat also looks better that way!

 

I never could bring myself to apply a polymer (teflon) at an event, in case it brought me in to conflict with an over-zealous jury and the application of RRS 53.



Neither could I - on the grounds of laziness, but assuming you weren't blatantly applying some go faster lube in the dinghy park, it'd be hard to police wouldn't it. Without checking that rule, how easy is it to work out which Polishes and products are illegal or not.
 
True. Maybe it's the final frontier for exploitation...

Why not? They must have a fairly comprehensive chemistry lab to fall back on to test for substances ingested.
