Electrical question PA 14

I would like to find a way to hook my fish finder battery, Torqueedo battery, and Bluetooth speaker's internal battery on to a trickle charger so when I'm through for the day/week so it will charge everything at once without having to remove anything from my kayak. Power will be coming from my dock.
Any suggestions would be appreciated.

I think that's a bad idea as today's "smart chargers" sense the state of the battery and adjusts the DC current, up to the limit of the trickle charger as needed.

If you have more than one battery connected, the charger circuit could overcharge the battery/batteries, that does not need any additional current....it will shorten the life of the battery.
Just my take on the question.

2X what Steel Head said, and to add the comment: The inside of the yak is damp most of the time and the charger unit may not funtions as designed in a damp environment.

This is not advisable. Each of these batteries take chargers specific to the product. Overcharging could be a problem, also using a charging method like this will likely void warranty if something were to be damaged.

Thanks guys for the consistent responses. Based on your input three different trickle chargers going to the three types of batteries is the way to go. Any thoughts on a way to attach the trickle chargers to a switch plate or board mounted in the boat instead of crawling all over the boat to attach each trickle charger? Like a common point with three inputs plugs.

That will work if you do the basic wiring to each battery. Just splice on the additional wire to your battery connector so it reaches the battery to be recharged.
I personally prefer solder connections that are shrink tubed/insulated...this prevents poor/high resistance connections if they become wet.
