Catamaran Packet Builder — Denarau → Mamanuca & Yasawa

Three operators, three fleets. South Sea Cruises runs the Bula catamaran from Denarau, calling at Treasure Island, Beachcomber, Mana, Malolo and Lomani on the Mamanuca line, and at the southern Yasawa resorts on the Yasawa line. The Yasawa legs take 2–4 hours each way. They sell the most packets of any operator.

Awesome Adventures is Yasawa-only — they don't run to the Mamanucas at all. Their strength is the Captain Cook packet (3-island Bula Combo), which is the cheapest 5-day Yasawa loop. Their cat is older and slower than South Sea's.

Yasawa Flyer is the newest and fastest, a 26-metre cat built in 2019 that reaches the far Yasawa chain (Tavewa, Matacawa Levu, Nanuya Balavu) without changing vessels. Their packets are 4-, 7- and 10-day combos and are 15–25% more expensive than Awesome Adventures but the journey is smoother and the timetable more frequent.

Packet logic: operators sell in "Magic" / "Mamanuca Combo" / "Yasawa Combo" structures. A packet is locked to that carrier; you cannot mix a South Sea Mamanuca leg with an Awesome Yasawa leg without paying two single-leg fares, not a packet. The calculator flags this and suggests a single operator.

Sea state matters. The open ocean west of Denarau can run 2 m swells in the June–September trade-wind window — boats still run, but Yasawa passengers report symptoms in 30–40% of cases. Stinger-season (Oct–May) adds a no-swim rule at outer reef stops.

• Not real-time. Departures, capacity and packet availability change daily; confirm with the operator the morning of.
• Not a booking tool. Book at southseacruises.com, awesomefiji.com, or yasawaflyer.com.fj. Phone bookings attract a FJD 25 agent fee.
• Not for Kadavu or Lau. Those islands are reached by small-plane charter, not catamaran.
• Not a guarantee of weather routing. Operators sometimes divert to calmer resorts if Yasawa is rough.
• Not including resort levies. Most Yasawa resorts add FJD 30-50 per adult per night for meals and activities not in the packet — read the fine print.
