A raft is a very heavy boat (80 lbs).  It is made from 3 tree trunks tied together with 3 pieces of tying equipment.  If available, the use of a punt is preferred. You will need a sesta (or shovel) to push your raft, but a paddle can traverse deeper water. Rafts can be used to transport heavy materials such as logs along water.

To use the raft, equip either a paddle or a sesta. A shovel works for this as well. With one of these items equipped, step onto the raft, and move into a water square.

Note: The raft should be on a land square when you first step on to it.
