I often singlehand and use the thrusters to hold the boat against the dock when tieing up. I agree fully with PFW and Papa Charlies postsĪs much as a I appreciate the comments and insight my original post was focused on the difference, if any, of using a bow thruster vs a stern thruster (not both). And again - my question was not meant to stimulate a discussion of thruster vs no thrusters. I am curious about whether or not a 2x cost for bow vs stern thrusters brings with it a significant additional benefit.
Frankly at $20k or so I can’t afford a bow thruster but at half that I could consider a stern thruster. I can pivot our boat using the twin engines but try as I might (and I’ve tried/practiced often), walking sideways using twin screws and rudders on a 4788 is not that effective. But for example, with a starboard-to docking I could theoretically approach the dock bow in, do the clockwise spin thing to twist the bow even closer to the dock, and use a stern thruster to counteract the twist thus bringing the stern in to the dock in parallel to the twist pushing the bow toward the dock. Of course if more/most transient marina docks in the PAC NW used cleats instead of the devil’s spawn bull rails I probably wouldn’t care as much because I’m pretty good at stepping out of the pilothouse and lassoing a dock cleat I can use to maneuver around a spring cleat, but then I can’t change that situation so there ya go. I hope a few more folks will chime in with experience using only or primarily a stern thruster or who are curious and have done some experiments. Aftermarket stern thrusters dockstar professional#.
