The main difference of vertical type is that the profile deck is very compact as the motor and the gearbox are under the deck. With the help of this advantage, they are suitable for every kind of vessel and preffered more than horizontal ones in recent years. Vertical windlasses look more esthetic and offer more security for anchoring by making 180° chain wrap around the gypsy. If there are two anchors, positioning of the windlass on deck is much more flexible than horizontal ones. Also two independent vertical windlasses offer higher security comparing a horizontal windlass with 2 gypsy on 1 shaft. Since most of the mechanical components are under the deck, maintenance operations are slightly difficult than the horizontal windlasses.
