You know that moment when the fish are on and you're still wrestling the anchor up by hand? Bad timing, sore back, wasted minutes.

We just fitted a winch to this Extreme 570 and it sorts all that out. Drop it, retrieve it, move on. No more hauling chain when the workups shift.

Chase the bite instead of chasing your breath, which means more fish in the bin.

If you're keen, flick us an email or pop in and we'll talk you through what suits your boat.
