Junk rig to" in the junk rigged yacht is simple. Simply luff the boat into the wind with the sails close hauled and then put the helm down when the forward speed is spent. The battens will tame the luffing sails. Heaving to in severe weather is done by dropping the forward junk sails into their cradle and reefing the aft junk rigged sails—both tasks that are simplified by the junk rig. Heaving to in light winds can be difficult due to the lack of sail drive up wind. Annie Hill sailed a junk rigged dory and wrote of its virtues in

The original word was derived from Old French "ponton", from Latin "ponto" ("ferryboat"), from "pons" ("bridge"). When designing a pontoon bridge, the civil engineer must take into consideration the Archimedes' principle: Each pontoon can support a load equal to the mass of the water that it displaces. This load includes the mass of the bridge and the pontoon itself. If the maximum load of a bridge section is exceeded, one or more pontoons become submerged. Flexible connections have to
