I havn't spent too much time in Ryfylke, but it really is becoming one of my favourite areas of Norway. We just recently visited friends in Finnøy, and the other day we spent at some other friends cabin in Hjelmeland.
They have a Big Brother too. Same age as mine. And they are expecting a Little Sister in less than a month. Needless to say the boys (all ages) had fun both on and off shore. Little Brother and the girls hung out on land.
Except for a swim in the ocean. Beautiful warm (18 degrees) ocean. I have to do more of that in our holidays.
