Thomas Hancock had been shown a sample of Goodyear's rubber in 1842, but had not been told the process that made it—and Hancock said he had developed his process independently. The last of the suits were settled in 1855. Shortly thereafter, several people expanded on experimentation of rubber coated fabrics.

Among the useful things which formed a portion of our equipage, was an India-rubber boat, 18 feet long, made somewhat in the form of a bark canoe of the northern lakes. The sides were formed by two airtight cylinders, eighteen inches in diameter, connected with others forming the bow and stern. To lessen the danger of accidents to the boat, these were divided into four different compartments, and the interior was sufficiently large to contain five or six persons, and a considerable weight of baggage.

![Car carrying inflatable 3](https://upload.wikimedia.org/wikipedia/commons/f/f4/Car_carrying_inflatable_3.JPG)
The modern rigid inflatable boat (RIB) is a development of the inflatable boat, which has a rigid floor and solid hull. The external shape of the hull lets it cut through waves more easily giving a more comfortable ride when traveling fast in rough conditions. The structure of the hull is capable of supporting a more powerful transom mounted
outboard engine or even an inboard engine.
Soft inflatable boat
A soft inflatable boat (SIB) lacks the solid hull of a RIB and often has a removable slatted floor, so the boat can be deflated and transported in a car or other vehicle. Such boats have a low
draft
Draft, The Draft, or Draught may refer to:
