What do you all think about bow thrusters? Are they cheating? Do you recommned them? Or are they a waist of time? Are they expensive and what type would you recommend? If you had a fisher 37 would you recommend them? Are they difficult to install? I would guess that alot of purests don;t like them... but do you guys think that there is a place for them? What size would be appropriate for a fisher 37 (wood hull, 13 tonn weight) Anyways.... any help you have would be most appreciated. thanks. Brendan
