Yes, that is planing... albeit in short bursts due to the hull's inefficient shape. Thats talking heavy displacement yachts, I have had many mono hulls planing for hours... the Adams 10's love it when pushed hard under kite, they just go like a great big Malibu surf board.

Agreed about the GPS thing, not a good measure of hull speed.

Most of the Sydney Hobart Fleet over 60' can plane these days, look at the Volvo 60's etc etc...
