Anyone have some thirty?

[Rick H Kennerly]

|o| If you're at the beach and someone were to ask you if you had some
|o| thirty, you'd understand that he/she meant SPF 30 sunscreen. As
|o| sunscreens come in very specific SPFs (2, 4, 6, 8, 15, 30, 45) you'd
|o| probably understand if someone asked using any of those numbers.

Among cruisers here in the islands one also hears weight added to SPF
numbers--30 weight or 40 weight--mirroring engine oil viscosity ratings,
probably because we all do our own engine work.
