Yep
http://www.magicseaweed.com is a good site for checking wave patterns and heights. Long deep swells are relatively flat in the open sea but can rise dramatically as the ground underneath them shallows, especially if the swell is also being funnelled into a deep gully or bay. This is very common on rock marks on the west coast from Cork to Donegal and people should be aware that storms hundreds of kilometres offshore are capable of creating massive swells. These will occassionally lose their rhythm and pile up on each other, in effect doubling the size of the swell. This is one of the causes of "freak waves" which are far more common than people realise. You should fish at least 5 metres above the tide line and be aware that swell will reach higher on a flooding tide than on an ebbing tide. On most rock marks, you do not need to fish at HW only...
The old line "never turn your back on the ocean" is always good advice.
Anyone fishing a rock mark at any time of the year without mates and certainly an automatic lifejacket is a total fool. They are needlessly endangering themselves and people sent out to search for them.
An automatic lifejacket gives you a chance if you are swept off or fall somewhere and for less than most people would spend on a new rod.
Other useful options are a piton hammered into the rocks and a safety line (extreme but if you fish a mark regularly its well worth it) and if you can not hammer it in, you can buy cement - fast hardening stuff - that sets harder than metal. I know one place where a guy has built his own platform from concrete including metal railings but well, that is true dedication! :wink: Would not have believed it unless I had seen it!
Having a thermal blanket, waterproofs, a change of clothes, first aid kit (and training in how to use it), ropes, various mobile phones to maximise coverage between networks close by (and not half an hour away in the car boot) are all intelligent options for rock fishing.
You can use rod sections and line to make a splint in, only seen this done once and it was a bad compound fracture so I never want to see it again.
BTW wool keeps you warm even if it gets wet a tip I got from a Canadian mountaineer which I unfortunately got to test - and yes it is true!
Any other safety tips, people might collect them here and we will put them together in a PDF or simple guide...
Thanks
