Summary of Multihull Advantages
Multihull Advantages | Multihull Drawbacks |
Unsinkable – foam construction and more watertight bulkheads | Usually more expensive, length for length |
Non-heeling environment | Will stay inverted when flipped |
Higher average speeds | Bridgdecks can slam if not high enough |
More interior space, 360 degree views, optimized layout | Not as easy to find dock space |
Shallow draft – safer and more access to harbors, more anchorage possibilities | Usually performance decreases more rapidly than a monohull when overloaded |
Twin engine and twin rudder redundancy | Windage can be high |
Safer sail-handling and reefing procedure | Quicker motion, especially sailing upwind |
Better interior steering station – often forward facing | Not fleet-friendly racers |
Better protection in cockpit against sun and rain | More maintenance |
Better autopilot function | |
Ability to beach and access for repairs | |
Better maneuverability in harbor | |
More deck space and user friendly trampoline | |
Better ventilation possibilities via emergency hatches, even in rain | |
More confidence-inspiring for beginners / less seasickness | |
Longer range and more efficient under power | |
Galley-up location | |
Separation and privacy of twin hulls | |
Lower environmental impact – more efficient | |
Dries out upright | |
Easier access from water via transom steps | |
Better dinghy storage on davits between hulls |
