Well we have a 12v auto bilge pump and battery but I love my gadgets so I am now adding a 20w solar panel to feed into a switch panel with USB & 12v connections.
This will allow the panel to trickle charge the battery to keep pump available and also I can than stick on my tablet running Navtronics app & keep the GPS/VHF charged too.
Its a bit of an overkill but will make life easier and Im all for that. Will add a white Nav light on a pole so we can do some night time runs in the Sound too.
Its all going in a small snaplock box so will be IP64 at least (dust proof & splash proof)
Will post pics when all assembled at weekend...
