First Claim
Patent Images
1. A marine vessel and drive combination comprising:
- a marine vessel comprising a hull having a longitudinally extending keel having a lower reach, and port and starboard lower hull surfaces extending upwardly and laterally distally oppositely from said keel in V-shaped relation;
a port tunnel formed in said port lower hull surface, said port tunnel having a top spaced above an open bottom;
a starboard tunnel formed in said starboard lower hull surface, said starboard tunnel having a top spaced above an open bottom;
a port marine propulsion device comprising a port drive shaft housing extending downwardly in said port tunnel to a port lower gear case supporting at least one port propeller shaft driving at least one port propeller;
a starboard marine propulsion device comprising a starboard driveshaft housing extending downwardly in said starboard tunnel to a starboard lower gear case supporting at least one starboard propeller shaft driving at least one starboard propeller.
