What is the best knot that not only will stay tied but is easy to untie
and where can I find an example of how to tie it, please ?

That will depend on what you need the knot to do. Lots of books out there.
Try the marlinspike sailor by Hervey Garrett Smith. Lots of basic knots and
how to tie them as well as what they are good for.

The most comprehensive book you'll ever find on the subject is "Encyclopedia
of Knots and Fancy Rope Work" by Graumont. Easier to follow for the average
bear is "Ashley's Book of Knots." Hervey Garrett Smith's "Marlinspike
Sailor" is also very good, and I would list all three as essential for any
ship's library.

We use poly rope for stern tying up in Desolation Sound. I use the
same knots for any given application that I would use for other lines
except that I tape the bitter end off with electrical tape because poly
does have a habit for coming undone?

Poly rope, because it floats, is great for stern lines which are needed on
crowded anchorages. Rather than tying it off, we loop it though a ring or
around a rock or tree and back to a cleat on the boat.

Poly is also used for painters, in which case it is spliced to build to the
bridle.

If you do need to tie a knot, you might whip the loose ends. Cut the whip
to untie the knot.

BTW - to what purpose will you use poly line.

Replace the poly rope with something reasonably decent. Poly does not hold
knots, and deteriorates quickly when exposed to the elements. It DOES
float,
which is helpful for some light duty uses, but the junctions need to held
be
secured with more than just a knot.

Thanks for the interest of all.

The immediate use is to tie a tarp down so you see my concern about it
staying tied and being easily untied, I was given 600' of 3/8" and other
than dinghy painter have no other use for it, so am going to use it to
secure the tarp.

I'll whip the ends with electrical tape but what particular knot would
you use, given my application ?

Gratefully,
Courtney

When I worked in the GOM for a diving contractor we used that
yellow/oranag poly often for attaching a bouy to a pipe.The stuff is
very slippery. The constant motion of the sea will work harder than a
raccoon to undo most any knot with great success. There are two knots
that I have used for poly in the water:

1) The Poly Knot, to make an eye with braded or three strand.
2) West Coast Dungi Crabber's Bouy Knot, to attach two bitter ends of
similar size three strand poly.

Would you like instructions?

You have to tell us whether you mean Polyester, of which Dacron is a
brand name, and is used for all sorts of running rigging, or
Polypropylene which is a much weaker rope, but which floats and is
used for water toys, etc. There is a huge difference in their ability
to hold knots.

While you're at it, you might tell us the application and the size and
type of line. For example, cheap polypropylene won't hold a bowline
at all, but some of the modern forms will.

Also, be careful taking advice from the traditional books, such as
Graumont or Ashley, since both types of "Poly" came into use after
these books were written.

I'm sure you know that polypropelene doesn't handle uv well.
Don't know how long you expect to have this tarp erected, but maybe it's
made of the same stuff, so won't matter.

Thread poly thru tarp grommets from side to side under boat, like
lacing a shoe, then whip a 12" loop in each end.

Thread end thru a gallon plastic jug handle that is full of water, and
allowed to hang a couple of feet of the ground. Whip loop to hold jug.

Get a beer and think of more questions.

For the tarp end, I would use an end splice (Bitter end goes through the
grommet then through the middle of the line itself and then wraps around
and back through the middle of the better end (6" up) and then it feed
up the center. The end of a pen of a proper fid will help.

Where you tie it, I would use 4 half hitches and then wire tie the
bitter end so it can be undone

Seems to me it's fair to assume he's asking about polypropylene, since
there'd be no reason to ask about polyester lines. In fact I see no reason
to even ask your question other than to demonstrate your knowledge of
chemistry.

Sorry, I had actually composed a response assuming polyprop and then
realized the ambiguity. Part of the problem, however, is that
nowadays the newer forms of polypropylene will hold a know rather
well, so to answer the question, one must know what type it is, and
what the application is.

For holding down a tarp, I'd throw away the presumably cheap, slippery
polyprop and go to the Home Depot where you can buy a lot of line that
will hold knot and is cheap enough to just chop away in the Spring.

Not sure I understand.

Are you saying the plastic jug handle had chafed thru or was it the
line at say a grommet?

Never had a problem myself, but then I usually checked the boat at
least once between November and April.

Yes. Leave longer tails than normal and tape them.

Look up knots for fishing line. Poly acts a lot like monofilament when
you tie it, so some of the fisherman's knots should work.

Thank you. I'm using very cheap 3/8" polypropylene line. I have Ashley,
and that's why I'm tryin' to get experienced user's comments.

Cordially,
Courtney

Dunno. It wasn't my boat, and I didn't look closely. Just noticed the jugs
on the ground and the line ends loose.

I remember seeing the same thing at my yard - I forget where the
failure point was (I's guess the grommet), but there were several jugs
lying on the ground and I remember thinking "there's another cute
solution that didn't work." A issue with polyprop is a low melting
point, so any chafe point that causes enough friction to heat up is a
potential problem.

I did a quick scan of rec.crafts.knots and my newer knot books by
Budworth - they all acknowledge the problem with polyprop but offer no
easy solutions. I've always added several extra hitches, and opened
the lay to tuck a generous tail through. A wrap with electrical tape
would work, and now that I think about it, a cable tie would probably
do a great job of securing a knot.

I have not seen thjis knot suggested:

Double figure eight - it is used by climbers. Their ropes are more slippery
than yacht rope. Instructions on this page.

Why not but a spool of the 'waxed whipping twine'?
It'll go a long ways and it's not too expensive.

Interesting reading, thanks for the link.

But, as I mentioned before, books that are written with natural fiber
rope in mind are not much use for picking a knot appropriate for
polypropylene.

Good question.

I just kept a spool of mason's twine and a hockey puck size piece of
bees wax in the ditty bag.

Got double duty from the mason's twine when it didn't have to be waxed.

Jeff,

Great idea on the cable tie. I think I'll use rolling hitches, with
elec. taped whipped ends and cable ties.
