    While watching the AC 2017 I wondered what makes the safety-, camera- and support-boats of the teams are. Anyone can help?

    Haven't paid close attention but if you're talking about the RIB support boats, usally Naiad and Protector.

    ETNZ have an interesting Support Boat - http://www.salthouseboats.com/production-boat-catalyst45.html

    A presentation on the previous version was interesting with some clues into the design process.
    • When chasing a boat capable of 40 knots, some serious speed is required to overtake or move around it to analyze performance.
    • A sail boat on foils is above the chop while the support boat takes a pounding while chasing.
    • Efficiency is important as the sail boat uses no fuel and would sail all day (subject to crew endurance) due to limited days of testing. Regular trips to refuel hindered testing.
    • 2 engines could be more efficient than 4, but the grip of 4 on the water is required to right a capsize.
