The tag "seamark:type=rock" is inappropriate for islets. Ir should only be placed on nodes that are offshore. See: http://wiki.openstreetmap.org/wiki/Tag:seamark:type%3Drock

Comment from CyrusDreams
When I searched for the tag "islet", I was referred to the overview page at: http://wiki.openstreetmap.org/wiki/DE_talk:Tag:place%3Disland
Most is in German, but in the English section the difference between rock and islet is made by size. Since the dimension of the objects was smaller than 20m at least in one direction (if not both), I opted for "rock". -

That wiki page is discussing values for the "place" key. Therefore, you would use "place=rock", not "seamark:type=rock"

Comment from CyrusDreams
It isn't discussing "place", it is discussing "place=island" and distinguishes this tag from others. In fact, taginfo shows only 6 hits for "place=rock" and zero for "place=rocks". That is a strong indication that the proper use of "rock" is in conjunction with "seamark". Also keep in mind that rock can also mean a landmark on the ground. To proper indicate that the rock is in the sea, you have to use "seamark".

Sorry, I mis-read. The important thing is that an area which is tagged with "natural=coastline" cannot be tagged as "seamark:type=rock" as the definition of the latter is an object which is "awash or is below the water surface". An area within a coastline is by definition above the high tide level.
