    I have small very heavy dinghy and I want to build an wave glider oscillating foil propulsion wing system for it.

    Do I need bigger system ? Any power calculation or dimensional decision ?

    I want to use it with hanging to a cable and cross med in summer.

    Any idea ?

    ps. I found too many patents belongs to the liquid robotics. One of them is at the next post.

    Wave Glider Specifications
    • Water Speed: Typical 1.3kts
    • Endurance: Up to 1 year (varies based on operating conditions and location)
    • Operating Water Depth: > 15m
    • Station Keeping: 30m radius
    • Payload Capacity: 7 modular bays (93L)
    • Tow Capability: 500kg (drag dependent)
    • Average Continuous Power: 5W – 20W
    • Max Solar Collection: 192W (nominal)
    • Battery Capacity: 0.9kWh – 6.8kWh rechargeable
    • Communications: Satellite, Cell, Wi-Fi
    Wave energy is greatest at the water’s surface, decreasing rapidly with increasing depth. The Wave Glider’s unique two-part architecture exploits this difference in energy to provide forward propulsion.

    VEHICLE CONFIGURATION Float and sub joined by 8m (26ft) umbilical tether FLOAT DIMENSIONS (L x W x H, with recovery buoy attached): 305cm x 81cm x 23cm 120in x 32in x 9in UMBILICAL 8m standard SUB DIMENSIONS (L x W x H) 220cm x 145cm x 33cm 87in x 57in x 12in WEIGHT1 (Dry, without payloads) Float: 71kg (157lbs) Sub & umbilical: 84kg (185lbs) Total: 155kg (342lbs) MAX. MISSION DURATION Up to 1 year2 WATER SPEED Typical: 1.3kts MINIMUM WATER DEPTH >15m with 8m standard umbilical OBSERVABILITY Low noise propulsion system Minimal visual/radar signature Optional flag and marker light Optional placards

    Wouldn't that be about like hanging off the back with a pair of swim fins on and kicking? Or have I grossly misunderstood something here?

    I think its a very good example but I think kicking with swim fins done at the 8 meters deep where there is no fight and may be force arm is long enough.
