Take the catamaran
Half-days at Lembongan, families with young children, seated lunch under way, and anyone who has been seasick before.

Motion sickness
Neither is better. The catamaran wins a lazy day at anchor with a table; the motor yacht wins a day where crossing time is what you are buying back.
Where each one wins
Tell the desk what the day is for and it will tell you which hull that day wants.
Half-days at Lembongan, families with young children, seated lunch under way, and anyone who has been seasick before.
Full Penida days where the crossing is dead time, degustation dinners, and any block where the clock is tight.
Capacity is set by the vessel's certificate, and seated dining always takes materially fewer guests than standing. The desk checks that before quoting.
Send the date, the party size and what the day is for. The desk replies with the hull that day wants and what it costs.
