No worries. Similar in my case. I could have taken a sounding but instead I just took the word of several who were tied up at the same sea wall! To paraphrased President Reagan, I should have trusted them but verified it also. Oops.

Well, having just run aground AGAIN (this time on a rising tide) I should have wondered why the guys in the runabout went around the wrong side of the channel marker.

Not having a great morning.

The good news is that you are alive, no one is hurt, and you are not holed nor sinking. In a few weeks you'll look back and laugh at it, but you'll also be wiser!

I, and I am sure others, thank you for sharing this. I always try to learn from incidents of any type. I am glad to hear that you and your boat are all right.

I'm worried because I have not run aground for many years. Am I getting to old and cautious for this cruising business, am I losing my spirit of adventure.

You picked one of the easy ones GordMay, 3-4-5, 9-12-16 etc.

The first thing I usually do is jump in the dingy and haul on the spinaker halyard so that the boat lays over with the deck towards the shore and the bottom towards the fetch. Of course one cannot do it if deep water is on the wrong side.

If you are game I’ll give you a lift when I make it to your part of the world.

PLENTY of adventure, guaranteed.

Looking forward to it mate.

Don the same, but in my case the tide left the ground completely dry. I think the boat was at 60 degrees or something like that. Used the time to change prop axle seals and gutless bearing. The way up was kind of nerve wrecking. Even if your brain knows that the water will not enter the boat on the way up if it hasn't entered on the way down, there is a little devil in your brainthat tells you: "what if...... ."

You may want to read my post on dragging anchors and failed seacocks first... I’m in the middle of a bit of a bad streak at the moment.

Just saying.

But if you are still up for it then I’ll not question your courage. (Just your sanity.)

Ummm.... yeah.... about that....

I did like you said and replaced a failed seacock while the boat was leaning on her side.

Too bad I stuffed up and managed to twist the skin fitting in the hull, now I’m trying to arrange some slip time because it is leaking.

Edit: About now SV Jedi should chime in and (correctly) point out that would not have happened if I’d used flanged adaptors.

The tides with the biggest difference, between high and low water, are called springs, and those with the smallest are called neaps.
Spring tides happen just after every full and new moon, when the sun, moon and earth are in line.
Neap tides occur when the moon is in the first or third quarter , when the sun, earth and moon form a right angle.
When the new moon or full moon closely aligns with perigee (closest point to Earth in the moon’s orbit) then we have a supermoon, and extra-large spring tides (perigeean or king tides).

Ok, good summary, but do you know if there’s a name or way of differentiating between the two tides that occur within the lunar day?

So, for instance, I was lucky, I ran aground on a tide that only had a 1.2 meter range, whereas the following tide, 12 (ish) hours later had nearly a 2 meter range. I figured there might be a name for those two tides in comparison to one another. Or is that covered in your summary?

Refer #34....
and also https://en.wikipedia.org/wiki/Tide

under 'characteristics'

'Tides are commonly semi-diurnal (two high waters and two low waters each day), or diurnal (one tidal cycle per day). The two high waters on a given day are typically not the same height (the daily inequality); these are the higher high water and the lower high water in tide tables. Similarly, the two low waters each day are the higher low water and the lower low water. The daily inequality is not consistent and is generally small when the Moon is over the Equator.[6]
