A battery (718) includes at least one battery cell (790), a bidirectional port (781) configured to provide current output to a load from the at least one battery cell (790) and to receive a charge current from a battery charger (490) to charge the at least one battery cell (790), a charge only port (788) configured to receive charge current from the battery charger (490) to charge the at least one battery cell (790), and a battery control system (780). The battery control system (780) is configured to detect a connection status of the bidirectional port (781) and/or the charge only port (788) and, based on the connection status of each port, to control the battery (718) between a power delivery mode where current can flow from the at least one battery cell (790) out of the bidirectional port (781), a charge mode where current can flow from the bidirectional port (781) or the charge only port (788) to the at least one battery cell (790), and a disconnected mode where current cannot flow between the bidirectional port (781) or the charge only port (788) and the at least one battery cell (790).

A method (100) of controlling attitude of a marine vessel (10) includes identifying (102; 120) a natural roll frequency of the marine vessel (10), measuring (104; 122) a roll motion of the marine vessel (10) with an attitude sensor (36), and then determining (106;124) that the roll motion exceeds the threshold roll where no corresponding steering input is present. The method (100) further includes determining (108;126) a counteracting drive movement for at least one propulsion device (12a,12b) based on the measured roll motion and the natural roll frequency of the marine vessel (10). A steering actuator (21a,21b) is then controlled (110;130) to move the at least one propulsion device (12a,12b) to effectuate the counteracting drive movement so as to counteract an environmentally-induced roll motion of the marine vessel (10).

A marine propulsion system (20) includes at least one propulsion device (12a, 12b) and a user input device (22, 28, 29, 30, 32, 34, 100) configured to facilitate input for engaging automatic propulsion control functionality with respect to a docking surface (150), wherein the user input device (22, 28, 29, 30, 32, 34, 100) includes a direction indicator display (115) configured to visually indicate a direction with respect to the marine vessel (10). A controller (24) is configured to identify a potential docking surface (150), determine a direction of the potential docking surface (150) with respect to the marine vessel (10), and control the direction indicator display (115) to indicate the direction of the potential docking surface (150) with respect to the marine vessel (10). When a user selection is received via the user input device (22, 28, 29, 30, 32, 34, 100) to select the potential docking surface (150) as a selected docking surface (150), propulsion of the marine vessel (10) is automatically controlled by controlling the at least one propulsion device (12a, 12b) to move the marine vessel (10) with respect to the selected docking surface (150).

The invention relates to a marine battery charger cable extender (20) including a terminal end (30) that has a positive extender ring terminal (29) and a negative extender ring terminal (28), and a connection end (32) configured to connect to a terminal end of a pre-wired battery charger (9). The connection end (32) includes a positive ring end (27), a positive ring connector (38) configured to hold the positive ring end (27) and galvanic connection with a positive ring terminal (16) of the pre-wired battery charger (9), and a positive connection cover (40b) configured to completely encapsulate the connected positive ring end (27) of the cable extender (20) and the positive ring terminal (16) of the pre-wired battery charger (9). The connection end (32) also includes a negative ring end (26), a negative ring connector (37) configured to hold the negative ring end (26) in galvanic connection with a negative ring terminal (14) of the pre-wired battery charger (9), and a negative connection cover (40a) configured to completely encapsulate the connected negative ring end (26) of the cable extender (20) and the negative ring terminal (14) of the pre-wired battery charger (9).

A propulsion control system (20) on a marine vessel (10) includes at least one propulsion device (12a,12b) configured to propel the marine vessel (10) and at least one proximity sensor system (70,72,74,76,78) configured to generate proximity measurements (90) describing a proximity of an object (O) with respect to the marine vessel (10). The system (20) further includes a controller (24) configured to receive proximity measurements (90), access a preset buffer distance (50), and calculate a velocity limit (113a-f) in a direction of the object (O) for the marine vessel (10) based on the proximity measurements (90) and the preset buffer distance (50) so as to progressively decrease the velocity limit (113a-f) as the marine vessel (10) approaches the preset buffer distance (50) from the object (O).
