The one Sheet Boat
The one sheet boat, or OSB, is an outgrowth of the stitch and glue technique. The OSB is a boat that can be built using a single sheet of 4 foot by 8 foot plywood (1.22 m × 2.44 m). Some additional wood is often used, for supports, chines, or as a transom, though some can be built entirely with the sheet of plywood. OSBs tend to be very small, since the displacement is limited to a theoretical maximum of about 1500 lb (680 kg), based on the largest hemispherical shape that could be formed with the same surface area as the sheet of plywood. Though forming a hemisphere is possible (see geodesic dome), it is not practical, and most designs have maximum displacements of under 1000 lb (450 kg), and practical displacements only large enough for a single person.
Famous quotes containing the word sheet:
“There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period.”
—Auguste Rodin (18491917)
