Leafing through old newspapers I found this variant Bowline with tucking the end.
Was there text associated with, related to, this knot
in the paper? If so, please share that. (I can imagine
that the image doesn't match the words --typical.)
Is this a good quality lock? ... My primary interest is is to leave rope
in the sea without pressure/tension. (For example over the winter, my boat
is not in the mooring, but anchor and ropes wait late spring...) I would not
like to find the bowline open 
Thx, best regards

No. As Roo notes, firstly it takes care in formation.
Secondly, there really isn't any gain in slack-security
from the extension (to the original
bowline).
I don't know if this is still a valid URLink, but our Agent_Smith
has compiled a batch of
bowlines which includes some that
are secure when slack:
www.paci.com.au/downloads_public/knots/02_Bowlines.pdfNow, referring to the image you've presented,
here's a decent variation:
take the tail around the left eye leg in the
opposite direction (so, crossing first behind it);
and then swing it all the way over to encompass
the other eye leg,
AND THEN tuck it down through the turn it just
formed and the central nipping loop.
In this variation, one binds the legs of the eye
and so hold the central nipping loop's nip of things,
and gain security that way. (The SPart can still
ease through the collar into the knot, but it won't
loosen the nipping turn with this finish holding
that fairly tight. YMMV with conditions, but this
I think gives one a pretty good knot in many cases.)
