The challenge came in the following seas when the legacy swell was the dominant wave pattern. I was concerned that the bow would dig into the waves. While I ran the MC5 at 20 knots with the big swell on the quarter, probably the worst conditions for a vessel with this hull form, the steering took a bit more wheel to keep on course, but there was no cause for alarm. With the IPS, I was steering with propeller thrust, and this worked well when combined with the excellent directional stability of the hull. Overall, it was a solid, stable ride.
