Fishing with a paddle saves time, money and gas. Which rig fits your fishing style and home waters?
Sit on Top:
There are several traditional sit-in kayaks that are geared towards fishing (especially in rough or cold water) but sit-ons provide several advantages. For one mobility, in a sit-on you can readjust your legs to relieve sore parts. They're easier to get in and out of and provide more customization options than traditional sit-ins.
Drawbacks include heavier weight and susceptible to winds (which kayak isn't). Not for those with heart conditions, but great exercise and great for those on a shoe string budget.
Electric Power:
Kayaks are now available with built in trolling motors. Electric kayaks offer all the benefits of sit-on kayaks with none of its drawbacks. Traditional kayak fishermen will look down at you but does it matter if you're catching more prizes?
Drawbacks to an electric kayak are simply price. They are expensive rigs but still a good chunk cheaper then even the most run down tin rig you can find on craigslist.
Pedal Driven:
Why not put your strongest muscles to use. Biggest advantages off a pedal kayak are hands free mobility. With paddles the minute you reach for your rod you are at the mercy of wind and currant. Pedals allow you to hover in place and are MUCH cheaper than their electric driven counterparts.
Only drawback is you cannot pedal in reverse.
Paddleboarding:
stand up paddle boards are gaining popularity, many of them are large and sturdy enough for even you big boys out there. Standing allows you to see more of the water you're fishing, allows you to use your full range of motion when casting and they are extremely portable and light.
Disadvantages are obvious, one strong gust and you've been dunked. They're best in sheltered bays and calm days.
So take some time and analyze what kind of fishing you are going to be doing, take into consideration your main fishing waters and go from there...
