I'd like to hear from any 423 owners or similar hull Beneteau's about experience adding a bow thruster. Brand added, what cabling and interior disassembly is needed, where the battery is stored and finally if the forward water tank was "in the way". Those are the questions I know to ask. As usual many times it's not just what you know you don't know but also what you don't know to ask. Any info on brands, specs and cost is greately appreciated. Mine is a 2007.
