When I listen to the audio on Vid 1 I can hear a plane landing or coming in close. I suspect that the harbour is near a point and that some sea is wrapping around the point. I don't think the
camera is on a ship or it would move slightly too. Airports aren't close to ships either.
In that much wind on that type of cat the owner is probably doing what is needed to get in as fast as they can. Without an inner forestay and staysail the furled
jib would be pretty useless in pointing high into the wind and raising the main for what might have been a 2 mile
motor around a point would have been wild. As an aside monos and multis seem to
pitch pretty similarly. I once spent an afternoon watching a northerly come into a north facing anchorage. As soon as the wavelength of the waves got to half the boats LWL they started to really pitch. The pinched in bow, big bum monos did pitch a little earlier than their more even cousins but waterline length, full ends and low CG are important, not really how many hulls you have.
The other cat video doesn't really ring true. There may have been a gust at the same time the masthead ripped to windward causing an uncalibrated anenometer to read 53 knots but 53 is at the upper end of Force 10 on the
Beaufort scale "
Large waves (6-9 meters), overhanging crests, sea becomes white with foam, heavy rolling, reduced visibility." I didn't see this on the video. The waves looked about 1-2 metres. I don't think a tightly furled
genoa would be a good idea in this amount of wind let alone a half furled one.
Here in
Australia the difference between what the
weather bureau says is 50 knots and what some sailors think is 50 knots became a real problem in the 98 Hobart. On every
forecast is a disclaimer saying "
Wind gusts can be 40 percent stronger than the averages given here and maximum waves may be up to twice the height". It is important to understand that a consistent blow is very different from a
single gust on a moving
mast. When the
forecast is for 50 knots you probably should be tied up at home rather than looking at the anenometer.
