River Hamble entrance - an idea

Don’t forget that power boats at displacement speed are effected far more by the wake than sailing boats are as they have no keel.

I disagree. I believe a yacht under power with no sails set is more prone to rolling than a displacement power boat due to the pendulum effect of the keel. And at the location under discussion many of the yachts will be in the unrigged state, or at least only partially rigged.

You don’t understand a pendulum then.
The roll of a yacht will much much slower.

Agreed re the dangers of people forward. But that’s nothing to do with the pendulum effect.

I can only speak from experience. On one occasion sailing a Hillyard 6 tonner out of Pwllheli I came across a broken down speedboat with 4 people on board anchored in heavy swell a few hundred yards off Pwllheli beach. In order to effect a rescue we had to start the engine and drop the sails. In turning round to go back to the speedboat at one point I got her beam on to the swell when she started rolling gunwhale under to gunwhale under. The novice crew, the owner, was on the foredeck dropping the jib and very nearly went overboard. I've never forgotten that incident.
Maybe it's because the Hillyard was an old-fashioned long keel type of yacht that she rolled so badly but it's not true to say that sailing boats in general are less effected than power boats.
OK maybe I don't understand pendulum then, but as I said, I can only speak from experience.

Most power boats seem to be wider in the beam than an equivalent keelboat, so a bit less inclined to roll, but get the frequency of the waves, whatever their cause just right (wrong!) and things get uncomfortable, even in a multihull

This may be controversial but tbh if I were a motorboater I might expect yachties to be sea worthy enough to deal with wake...

Why? Do we really want to base the threshold of seaworthiness for a yacht on the amount of wake produced by a Sunseeker 66 accelerating onto the plane? Many of the mobos that cause excessive wake would founder in the conditions many sailboats can take when prepared for it. Should we ban them on the basis they couldn't cope with a F10? I do agree with the comment that the problem is caused by people who don't want to be educated and probably wouldn't care even if they where so we will just have to live with it but I can't say I see it as reasonable, just as I don't think a yacht tacking quite legally up a busy channel and causing a load of grief to a train of motor boats is acceptable.

If it's a recognised anchorage and, especially if there were children in the water, That sort of idiocy should be reported to CHIRP. Someone official having a chat is more likely to get an oik's attention than anything wee can do short of ramming the bugger.

Thanks I will remember that next time
