Hi Tauruck,
Plenty guys dive off fishing skis very successfully. I have done so, and so has Capespearo on this site - he got a ncie big yellowtail at St. Francis off it. Gives you quite a bit of range - quicker than swimming. Just need to figure out how to store your stuff. Also need to get one of the flat, stable fishing skis. Not many cons, other than having extra gear to transport and manage.
One question, thoguh: What on earth is a pink salmon? I'm guessing a rock salmon, or a Natal bankie?
Cheers,
Tony
