    Hello,
    I try to find the best propulsion system for a high speed planning boat,its a trimaran with these characteristics

    Length=10m
    Beam=5m
    Maximum speed=60 knots
    Cruise speed=50 Knots
    Weight=4.5 ton

    but i have problem to decide between stern drive and outboard propulsion systems.
    Also i want to know how many propulsion systems is more proper for this situation(i.e. 2 or 3)?
    Thank you.

    is this a high performance hull that you're looking for? what kind of water conditions are you going to be running in?

    sounds like you're going to need more than one outboard or high-hp I/O unit to achieve the performance expectations. hull design will be important in determining efficiency of your propulsion system.

    Dear jimboat,
    Thank you for your reply, you are right, it needs more than one propulsion system, in design procedure i have many restrictions so i can only use outboards or stern drive, what do you think about them, which of them is more proper?

    outboards will be lighter, so may be an advantage to you. you will require 2 of the largest o/b's available in order to reach the performance expectations you desire. design of the hull will ultimately determine if you are able to reach your goals.

    Dear jimboat
    Thank you for your reply, would you explain more about the hull design, which parameters do you think is important to achive this speed?
