I just got a sit on top kayak today shipped from Amazon. It has pre-drilled holes on the bottom like they are suppose to be there. Are these suppose to have caps on them? Is not it looks like water could come through it or is that how these work and the buoyancy keeps the water from coming in? Maybe a silly question but allot better than getting on a lake and not making it far.
Also I am in California. Anywhere great that is a must see for kayaker? Thanks!
