Hydrofoil with trolling plate

In combination,

• a base for attachment to a propulsion component of a boat,
• a trolling plate including a lockable member for travel in an arcuate path,
• first pivot means coupling said trolling plate to said base for trolling plate movement about an axis,
• spring means biasing said trolling plate in a downward deployed direction and said lockable member in an upward direction,
• elongate latch means having an elongate opening along which said lockable member may travel, a catch in communication with said elongate opening and in which said lockable member may be received to lock said trolling plate in place about said first pivot means,
• second pivot means located in a vertical plane and coupling one end of said elongate latch means to said base for travel of the latch means about a horizontal axis,
• said elongate opening of the latch means terminating at one end proximate said vertical plane to permit locking in place said lockable member, and
• control means coupled to said elongate latch means and operable by the boat operator to elevate same to release the lockable member for spring biased deployment.

In combination,

• a hydrofoil for attachment to a boat propulsion unit,
• a trolling plate including a lockable member,
• first pivot means hingedly coupling said trolling plate to said hydrofoil, said lockable member swingable about said first pivot means,
• a latch having an elongate slot with a catch for the reception of said lockable member,
• second pivot means coupling said latch to said hydrofoil,
• control means coupled to said latch and operable by a boat operator to position said latch to release the lockable member for travel along said elongate slot toward said catch coincident with deployment of the trolling plate.
