Tides are all about gravity. The reason we always see the same surface of the moon is because of the tidal force the earth exerts on the moon. The reason oceans rise and fall in a predictable rhythm is because of the tidal force of the moon on the earth. The reason the high tide is higher on a new moon is because the moon and the sun are in alignment, so you have tidal force of the sun and the tidal force of the moon pulling in the same direction.
BUT, I take your point. The wind could shift while I’m ashore, my wing keel could dig into some nice muck.
At 1500 lbs (the boat, not me) I’d bet I could push it out . . . But I haven’t tested that theory yet.
Im curious as to what other Capri 18 owners strategies are regarding going ashore. With such a small boat, towing a dinghy is problematic, as is storing an inflatable, but with that wing keel, you can’t exactly pull it up onto a beach either.
