Transportation
Decide how the kayak gets to the water before you decide which kayak. A roof rack with saddles or J-cradles costs $150 to $600 and works for hulls you can lift. A truck bed takes any weight but a 13-footer overhangs and needs a flag. A cart ($80 to $200) turns a 300-yard carry from a workout into a walk. An inflatable like the Sea Eagle 385fta sidesteps the rack entirely at 45 lb and a trunk-sized bag, with slower paddling as the trade.
Practice the lift and the tie-down in the driveway once before the first trip. Two straps over the hull to the bars, plus bow and stern lines; a kayak on a roof at highway speed is an airfoil.
Simplicity
A first kayak should have nothing on it that can fail. Paddle, seat, rod holders, a hatch, a tankwell for a crate, and accessory tracks so you can add things later. Rudders, drives, motors, live wells and electronics all come with parts, maintenance and weight. Add them when you know you want them, on the boat you already own if it accepts them (the Tarpon 105 and RS117 are rudder-ready; the Frontier 12 accepts a pedal drive or a motor).
Seat comfort
A frame seat holds you off the deck with back support; a padded deck seat is a cushion on the hull. If you are choosing between a $600 kayak with a pad and a $900 kayak with a frame seat, the seat is most of what the extra money buys, and it matters most if you plan long sessions rather than short ones.
Storage
A rear tankwell that fits a milk crate, a bow hatch for what must stay dry, and somewhere within reach for pliers and a small box. That covers a beginner's tackle. Center consoles, under-seat trays and gunwale tackle storage are pleasant but not decisive.
Paddle or pedal for a first kayak?
Paddle, unless you have a trailer or waterfront storage and a specific reason for a drive. A paddle kayak costs half as much, weighs 30 to 50 lb less, and teaches the boat control that a pedal drive hides. The least expensive pedal kayak here, the Hobie Passport 12.0 R at about $1,900 and 83 lb rigged, is the gentlest way into a pedal drive if you do go that way: kick-up fins, a removable drive and a modest weight.
