For beginners, here are some terminologies used in the sports of kayaking. The top of the boat is called the deck, while the bottom is called the hull. The back of the boat is called the stern and the front of the vessel is called the bow.
The cockpit is on the topside of the boat where the kayaker sits. The hatch is where your gear is stored. Rigging is where bungees are used to hold down your gear and paddles.
Scupper holes are drainage holes that allow you to drain the water through the kayak. Tracking relates to how straight the kayak moves. A Skeg is a blade in the hull of the kayak to help the boat go straight.
Usually you will find toggles at the stern and the bow of the kayak that help you lift and carry your kayak.
