Bow thrusters make life a great deal easier when docking
, and I love mine. That said, the judicious use of power and rudder
can do wonders in tight quarters, but if the slight drag induced by the tunnel and cost is not a barrier you won't regret having them. You might also look into hydraulics. Depending on whether you have a genset or not, a pump can frequently easily be added to provide sufficient flow for a thruster, as well as an eventual superior windlass
replacement. Hydraulics run quietly, do not burn out, are cheaper to maintain than electric
and the motors are more compact although powerful. This may be an impractical suggestion for your boat, but if it were possible to go this route
you might ask for a quote to have it to compare.
