Patent number: 6263825Abstract: A boat including a hull with a cockpit section, and a rear cabin section normally concealed by a horizontally extending cushioned deck element located adjacent the stern. The deck element is hinged along its rear edge so as to be elevatable to expose a sunken floor wherein sink and toilet facilities may be provided. An enclosure for the rear cabin area may be deployed to provide privacy for changing clothes or using the toilet. In combination with the sunken floor, the height of the enclosure permits a person to stand erect and move about freely. A portable toilet may be stored under a captain's chair immediately in front of the rear cabin area and slid rearwardly for use in the rear cabin area as needed.Type: GrantFiled: February 1, 1999Date of Patent: July 24, 2001Assignee: Duracraft Marine CorporationInventor: Samuel L.

Patent number: 6230648Abstract: A versatile motor boat having front and rear casting platforms and side platforms, a center console and oppositely facing, front and rear seat assemblies. Both seat assemblies can be opened to provide maximum seating when the boat is to be used for cruising. The front seat assembly may be collapsed to provide an extended front casting platform when it is desired to use the boat as a bay or striper boat. Both seat assemblies can be folded down to extend the front and rear casting platforms for use of the boat as a bass boat. When the seat assemblies are collapsed, supports are provided for a rigid back member forming part of each seat back and latches secure the seat backs in their collapsed position so that the rear surfaces of the rigid members provide stable extended casting platforms.Type: GrantFiled: March 15, 2000Date of Patent: May 15, 2001Assignee: Duracraft Marine CorporationInventors: Andrew M. Davidson, Samuel L. Davidson

Patent number: 6173670Abstract: A performance vee hull that can be made with conventional aluminum manufacturing techniques on a relatively economical basis. The hull uses the lift of a concave bow, the off-setting “hold down” of strakes without lift characteristics, the tracking and drag of a keel and an integrally formed off-set motor mount with a full transom to produce a “severe vee” hull configuration (10-15 degrees inclination per side, 20-30 degrees total vee shape). The hull has a curved, reverse or concave flared bow. A bottom surface of the hull terminates at a rear edge. Behind the rear edge is a set-back section. A transom extends across the rear of the boat, and is relatively flat all the way across. The set-back section extends rearwardly 4-8 inches from the transom and has a bottom surface that is above the bottom edge of the transom, about 3-6 inches.Type: GrantFiled: February 8, 1999Date of Patent: January 16, 2001Assignee: Duracraft Marine CorporationInventor: Samuel L.

Patent number: 6065422Abstract: A multi-function boat seat mount enables a single boat seat to be selectively attached to a seat mounting rail on a boat deck, or a pedestal support. The mounting system converts a prior art seat mounting plate on the bottom of a seat which includes a connector adapted to be attached to a complementary connector on a seat mounting rail, to a pedestal mounted seat. To this end, a separate pedestal mounting plate is provided which includes a rail having substantially the same configuration as the seat mounting rail. The pedestal mounting plate can thereby be connected to the seat mounting plate with a spring-loaded catch on the pedestal mounting plate engaging the trailing edges of the seat mounting plate. A spyder is carried by the bottom of the pedestal mounting plate with a pedestal element telescopingly engageable with a pedestal pole rotatably carried in a bushing on a pedestal base attached to the boat deck.Type: GrantFiled: June 15, 1999Date of Patent: May 23, 2000Assignee: Duracraft Marine CorporationInventors: Andrew M. Davidson, Samuel L. Davidson

Patent number: 5189977Abstract: To close off the cockpit of a small boat from a forward compartment of the boat, a lift-up panel hinged to the floor of the boat is provided to fit in the space between port and starboard consoles which separate the cockpit from the forward compartment. The panel fits against the floor of the boat when not in use and can readily be raised and lowered. Engagement of the panel with a central section of a windshield is provided to hold the panel in the raised position.Type: GrantFiled: February 21, 1992Date of Patent: March 2, 1993Assignee: Mastercrafters CorporationInventor: Samuel L.

Patent number: 4782240Abstract: The invention provides a safety battery connector which will shut-down the circuit in the case of an over-load and thereby prevent short-circuiting and the like. The safety battery connector incorporates a manually resettable circuit breaker which is connected between the battery and an associated circuit in order to break the circuit in the case of an overload. The device may include an over-heating indicator which is associated with the conducting plate.Type: GrantFiled: June 26, 1986Date of Patent: November 1, 1988Inventor: Samuel L. Davidson

Patent number: 4385580Abstract: A marine door unit consists of a rigid frame adapted to be attached to a deck and a door hingably connected to the frame. The frame is a rigid metallic unit formed of channel members, at least one of which carries a drain tube to prevent water accumulation therein. The frame means includes an inner upstanding support rail which carries a continuous sealing gasket. When the door is closed, the inner surface thereof abuts against the support rail, compressing the sealing gasket and rendering the door unit substantially leak-proof. In the event of any water leakage past the edges of the door, such leakage collects in the channel and discharges through the drain tube. The door unit is particularly useful on boats of the type having a fishing platform with a storage compartment beneath the platform. On such boats, the door unit is mounted in an opening in the platform and serves to keep the compartment dry while remaining substantially flush with the platform surface.Type: GrantFiled: March 12, 1981Date of Patent: May 31, 1983Assignee: Mastercrafters CorporationInventor: Samuel L. Davidson

Patent number: 4221014Abstract: A storage rack is mounted on boats of the type having seats supported by pedestals in order to store the pedestal posts. The storage rack is adapted to be mounted angularly for holding a pair of pedestal posts and consists of a pair of elongated cylindrical tubes, mounted side-by-side, and having a forward mounting plate and a rear support plate. The forward mounting plate is mounted angularly with respect to the cylindrical members so that when the mounting plate is attached to a mounting surface, the cylindrical members are disposed angularly. The support plate extends perpendicularly with respect to the tubular members and is provided with an opening or hole in alignment with each tubular member to prevent water accumulation and to accomodate the reduced diameter portion of the pedestal posts.Type: GrantFiled: April 25, 1979Date of Patent: September 9, 1980Assignee: Mastercrafters CorporationInventor: Samuel L.
