It would seem to be an accurate map of coastal and marine features, with a
scale in miles, probably land miles. The drying height shapes/extent around
the shore are much the same as a modern chart. The drying bank/ island?
marked Y as the Bramble is about 1.65 miles from X to X. In other words
about the 2m depth (below datum) line on a modern chart, not the current
small patch with a drying height maximum of 1m above chart datum. Was it
ever an island , with brambles perhaps ? lost in one of the earlier great
channel storms.
I don't know about the history of the Brambles Bank, but I played cricket
there last Saturday in the annual match between Island Sailing Club and
Royal Southern Yacht Club. Despite my brilliant bowling in the last
(maiden!) over RSYC won after 40 minutes, in a limited over match as the
pitch disappeared under water for another year then. Robin Knox-Johnston and
Rory McGrath were on the RSYC team and the whole thing was filmed for
someone, though I don't know who.
All great fun, but I digress, so back to the OP's thread please.......

Assuming air pressure at sea level I make the next extended uncovering to be
centered on 17.50 BST +/- 5 min on 19 September giving about 0.4m above
water level at
the peak and some exposed for half hour either side of that.
Where does all this once a year notion come from?

BTW did anyone else see other posts in this thread twice?
No. Just one of each of three.
You're probably right. Some bloke said it between overs and I haven't
bothered to check it.

The once a year tide rather than once a year cricket is on Wiki also.
I should have said this map is
" The River of Southampton (with? ) the situation of Bursleton Beauley &
Lymington"
I made it 11.3 sea miles from Hurst point to Calshot Castle on a modern
chart and 12.64 miles on the old map. Converting 11.3 by 6000/5280 gives
12.84 so it must be land miles , so Bramble was then 1.65 miles long.
and atmospheric pressure, the standard 1013mB, got lost in the OP

That amount of inundation doesn't seem too unreasonable: the south coast has
been steadily sinking of the last n-thousand-odd years (because the ice
melted later in Scotland, so the north is still rising as a result of the
weight coming off it), so there'll have been some rise in sea level since
1700-odd. Add to that erosion as the bank becomes more and more submerged
more of the time and loss off the top seems quite plausible - as does an
origin as an island back maybe a thousand years before that.

I note that the map seems to show double lines for coastal outlines,
presumably low and high water contours. The Bramble is drawn with only
one line, so that'll be its LW contour. The absence of a HW line suggests
that it wasn't an island in 1698,but evidently it was bigger then than now,
so as you say it could well have been an island earlier.
