Anchoring a multihull with success requires choosing the correct location, having the right anchor for the boat size and bottom conditions, setting the correct chain and rode arrangements and ensuring you bury the anchor effectively.
There is no anchor that covers all bottom conditions. Most multihulls should carry two anchors of different types. The classic brands come with recommended weights for yacht length – but also consider how much windage your multihull makes. Don’t underestimate the required anchor weight because your multilhull is lighter than a monohull of equivalent length.
Multihulls put a different load on anchors as they sail on the mooring line.
Windage is important when selecting the anchor size. Some multihulls are aerodynamic and low windage. Others have a profile with flat surfaces that create high windage.
In most situations, multihulls need about one size bigger than for an equivalent-sized monohull. In
