East cork yak fishing

I got a kayak a few month back and now feel confident enough to fish from it I was just wondering if anyone could point out a half decent mark so I can try my hand at it. Anywhere between west Waterford and around cork harbour would be perfect.
Also is it worth splashing out on a fish finder?
How many times have people flipped these while fishing? (I'm prepared for it I just don't like getting wet!!)

Cheers Alan

There is a Irish site full of yak anglers that will let U no everthing U need to no just google it. im angling from the yak about 6 months now im from Dublin so the shore fishing is not so good. Now I have the yak I was out 2weeks ago had cod to 7lb great crack pulling fish up in the kayak. Serious check that site out

I meet these guys on the water regularly: http://www.irishkayakangling.com/

Me and Kev had great crack a few weeks back on the yaks. Good luck it's a great way to fish

Thanks for the replies all.
Can't wait for this weather to break its driving me mad at this stage...
