Would you care to comment on the comfort of the vessel in waves; i.e.,
roll and pitch?
My impression from the manufacturer's video (in what was reported to be
a fairly mild sea state) is that the ride might be rather
uncomfortable.

The video was done on a day with 15 knot westerly winds, and a low
underlying swell which doesn't show in the video, which was taken from shore
with a telephoto lens. I was driving the boat at the time, so I can tell you
about the ride.

In the conditions we had for the filming, the ride was smooth and cushioned.
The boat does move around, but the g-forces are low and in those conditions
she never slams or pounds. On the day Georgs was out with us the waves were
bigger, but the ride was still well controlled and comfortable.

When stopped in a swell, the boat has a slightly snappy roll which I don't
care for, and I think this is what showed in the video, where we were
approaching the unprotected Dundarave pier at very low speed.

Last month I started Northwards up the Sunshine Coast (an aside, tourism
increased greatly when they changed the name from the Rain Coast sometime in
the 60s). The Weather Radio was forecasting a Northwest Gale, a small craft
warning was in effect, and the wind was 20 to 25 mph on the nose, with a
strong tide against the wind. In these conditions the motion was very
uncomfortable, and we were not able to find a comfortable speed. Too slow
and we were tossed around by the waves, too fast and we became briefly
airborne before crashing down. However, the only other boat we saw heading
North was a large "Expedition" type trawler, about 80'  and he was plunging
heavily into the waves, throwing spray over the flying bridge. Nevertheless,
he continued on at about 8 knots. We chickened out, turned around and surfed
back into Howe Sound. The boat took the substantial following sea well, with
no tendency to broach and very little steering required.

As with sailing multihulls, she is more comfortable down wind than a
monohull, which typically tends to roll a lot and tend to broach in those
conditions. Upwind I can't say, as I have never tried a 29' monohull
powerboat upwind in those conditions. My 37' sailboat could have powered
upwind at 5 knots in those conditions, but would have thrown a lot of spray
onto the windshield.  The MC29 remained dry on deck despite the rough
conditions.

The Seattle trip was very easy, we never encountered any seas bigger than 1'
except the mention Bayliner wakes, which didn't bother us when meeting then,
but when passing them from astern, did take some steering as we crossed the
wakes at a just slightly higher speed.  By the way, all the way from
Vancouver to Seattle, not a single power boat of any size passed us,
although a C-Dory 25 kept pace with us for a while before slowing down for
one of those Bayliner wakes (from ahead) then turning up another channel.

The boats we passed were mostly trawlers traveling at 8-9 mph and
Searay/Bayliner/Carver type running at about 15-18 MPH, just a bit slower
than us.
