Space & comfort
Catamarans win on space — decisively. A 45ft catamaran offers roughly twice the living area of a 45ft monohull. For families or groups of 6–8 prioritizing comfort, the space advantage is significant.
Sailing performance
Monohulls generally offer a better pure sailing experience — they heel, respond to the helm more intuitively, and reward skilled boat handling. Catamarans are faster on most points of sail but their large beam makes them unwieldy in marinas.
Stability
Catamarans are dramatically more stable. Ideal for guests who get seasick easily, for children, and for anyone prioritizing platform stability over sailing sensation.
Cost
Catamarans typically cost 40–80% more than equivalent monohulls to charter. A 45ft monohull: $2,800–$4,400/week. An equivalent catamaran: $5,000–$7,700.
When to choose a catamaran
6–8 people aboard, someone prone to seasickness, hot climate, Caribbean trade-wind route, or comfort is the priority.
When to choose a monohull
Fewer than 6 people, you want the "real" sailing experience with heel and spray, budget-conscious, or flexibility in marina berths.
