Vertical anchor windlasses place the chainwheel on a vertical drive shaft above the gearbox and motor, which are mounted below deck. The “topworks” can thus be lower in profile. Vertical anchor windlasses often retrieve combination rope/chain rodes. The anchor rode should lead to the windlass parallel with the plane of the chainwheel for best results. The lead should be within 5 degrees of level to the chainwheel for the best results.
An anchor windlass should normally be mounted on the yacht’s centerline with the chain in close alignment to a line drawn from the chainwheel through the bow roller (or chock) to straight ahead in the water. It is important, especially for combination rodes, to locate your windlass so that, as rope is stripped from chain-wheel or drum, it can “fall” directly into the rope locker.
The location and depth of an anchor locker are important elements in an anchor windlass installation. When the rode is in the anchor locker, the top of the anchor rode should be a minimum of 16’ below the underside of the deck. The anchor locker should also be positioned so the chain and rope feed through the windlass deck plate or hawsepipe directly into the deepest section of the anchor locker.
