Abstract
1350103 Oars ESTUARY MARINE Ltd 24 Nov 1972 [25 Nov 1971] 54803/71 Heading B7V An oar is manufactured by injection moulding of a self-foaming and self-skinning polyurethane resin and has an insert of timber or bamboo which reduces the flexibility of the oar. The insert extends coaxially along the whole length of the handle and loom and has a tapered outboard end which terminates in the blade. The insert may be circular in cross-section and have a diameter between 1/3 and ¥ of that of the loom. If the insert is not circular in cross-section its longer axis is normal to the blade. The insert may have a moisture content below 14% to facilitate bonding of the plastics to its surface.
