If I wanted to go out in a F8 gale in a Mobo (and I have been in one), my first choice would be any of the RNLI lifeboats - the seakeeping qualities of the olders Arun and Waveney classes are legendary, while the newer boats like the Severn and Trent class vessels are amazing - I will always remember going out on sea trials off Poole on FAB 3, the Severn prototype, and bashing into a F 7 doing 25 knots...... we needed seatbelts on in the wheelhouse, otherwise we would have been hitting the roof with the G forces.....
But my 2nd choice would definitely be a Nordhavn or similar.
