You should allow the bow to lift a bit, to get air under the hull. Right now, it acts like a snowplow. If you make 1/3 of the flap hydraulic, you can adjust as you please an watch the GPS for maximum output. However, it is still a deplacement boat, weight is about 3 ton, and there will be drag, unless you convert it to a hydrofoil and install 400 hp to lift it out of the water.
That is a Miracle...🎱🐽😂We, in the Mediterranen were made to belive it was a ''North Sea'' Saling boat in 1983...🐖 And you were '''sraght in the water''' if you did not wach your step and footing down the ''Narrow side walks'' when you whent to pull up the Rigging, on the constant Rock and Roll of the Saga 27 side walks out at sea, ''on a calm day''...? 🤢🤮But now I see how this vessel used in the Calm Baltic Seas and Fiords, Lakes with no ''calm under swell'' and it could be used in Canals...?😜Thanks to Peoples Vlogs and IT, Google Earth. etc.
