Yes. Essential on a long keeled yacht like a Fisher that can be difficult to manouvre in a tight space. I have one on my Fisher 25 and would not be without it. My previous boat was a Coaster 33, very similar shape and characteristics to the Fishers. My first move when I bought it was to fit a bow thruster. When in Calais I had the mast taken out in order to go into the canals, I had to back quite a way back along a narrow waterway from the crane and the only way I could do it was by using the bow thruster [steering by the bow, as it were]. I cannot give advice on cost or type, but it will save on gel coat repairs [yours and others!].
