A spin-off of the evolution of Oileáin is the possibility to reflect the activities of Irish sea kayakers in the late 20^th century. Kayakers measure their performance in many ways. Some always want distance, some want scenery, caves, rough water, ceteceans, headlands, islands. But some, a few, want difficult landings, normally difficult island landings. Mountaineers have their first ascents, but some kayakers, like astronauts, count first landings. I have attempted to chronicle in some small way an aspect of all that here.

Landings anywhere can be difficult with conditions, but this study considers landings that are achievements at the best of times. On the one hand this virtually always requires the absence of a technically easy landing once the kayak has arrived, but there are exceptions. An exceptionally difficult passage (e.g. Inishtrahull) can sway the balance. Exceptional good luck or swimming ashore is usual. On the other hand, technical difficulty would rarely if at all be enough of itself for this study, unless extreme. A remote rock somewhere is almost always in question. There is usually a combination of factors. There always needs to be some off putting factor also present. Introduce technical difficulty, or distance off the land, or remoteness otherwise, and/or off-putting currents or conditions, and the recipe becomes complete.

Such remote rocks often have lighthouses. Landing onto hard rock from a kayak is entirely different (and almost always more difficult than) from other boats. One steps off a boat onto rock at the same height, but one slithers out of a kayak up onto rock. Remote lighthouse rocks tend to count.
