Dunno, that's just what I was last told.
I was a bicycle mechanic for many years, and can tell you that only a very bad mechanic would use grease on chains and gear.
Grease is a thick lubricant designed for use in bearings as a general rule. Chains and gears on a modern bicycle are not greased, but are generally treated with a dry film lubricant
, which is quite similar to Boeshield T9. In fact, many cyclists I know who also sail, use T9 for many things on their bikes and boats.
While I'd agree that "no grit and no grease" is better than "grease and grit"....When I was worked in the bicycle shop, I'd fire any mechanic that was dumb enough to use grease of any kind on a chain or the exterior of the chain rings or free wheel gears. Grease is also thick enough that it can hinder performance if too much is applied.
I think the major difference between winch grease and a bicycle grease may be the composition of the anti-corrosion additives used. But some of the bicycle grease compositions are fairly good as bicycles hubs and bottom brackets, especially on mountain bikes and those used by bicycle messengers, see a fair amount of grit, water and often, salt.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
