Two schools of thought - Sit on top - or Sit In SOT
vs SIK
It has been debated to the nth degree - and I think it comes down to personal choice
From the SIK school - the Pungo by Wilderness Systems is one of the great choices
Can you go wrong with a Yak - I really dont think so - some guys truely " PIMP THEIR RIDES" with multiple rod holders - fish finders - temp guages
GPS
Me - two rod holders
Dress appropriately
Wear a PDF
a tie down for your paddle ( so you don't loose it )
a tie down for your rods - ( in case you dump the yak)
Choose the days / conditions that you will and won't go out
discretion is a really good thing
there are some great sites for specific to Kayak Fishing
