Abstract: A self-loading tool 2 for removing snow 10 from a surface 12 includes a blade 4 attached to a handle 6. Handle 6 is attached to a neutral plane 24 of blade 4 at an angle between about 65.degree. to about 85.degree. and preferably about 75.degree..

Abstract: A boat lift includes a vertical H-beam driven into the floor of a body of water adjacent a pier. A shaft housing surrounds the H-beam and slides up and down it on rollers mounted within the channels defined between the opposed flanges and web of the H-beam. A fork lift-like boat support is mounted to the shaft housing for vertical movement therewith to raise and lower a boat to and from the water. Forces are transferred from the shaft housing to the H-beam by the rollers engaging the web surfaces and the inner flange surfaces. A hoist, supported by the pier and the top of the H-beam, raises and lowers the shaft housing and boat support therewith.
