This is an interesting and very timely thread. I need to replace a genoa
halyard and assumed an eye splice would be needed. Had never contemplated a
knot on anything larger than a 10’ dinghy. What type of line are people using
that are tying any of these knots? Some line is considerably
I, too, learned the fish knot as a kid and still use it (for fishing).
FWIW, an old friend of mine who is a semi-retired sailmaker and highly regarded
sailor told me that he uses bowlines for halyards on his 50-something foot
ketch, which he races from time to time on distance races. This is
Can’t speak for the confined space rescuers, but the climbers switched from the
bowline to the figure eight, mainly, because the bowline CAN untie by itself
under certain situations.
Generally, the bowline is frowned upon in the life safety situations.
However, when I was learning to climb (a
I do not recall if this was mentioned on the list before or not, but read in
the Boat US magazine last night that Kidde has recalled over 40 million fire
extinguishers with plastic handles or plastic push buttons manufactured
between January, 1973 and August, 2017. According to the US Consumer
Here's a question for your collective wisdom:
We regularly have fog here in Maine, and my normal practice is to hoist a Davis
emergency radar reflector in the shrouds (so I hopefully will not get run over
by a lobster boat). So this year I decided to get the yard to mount an EchoMax
Here's a good article with a wee bowline
mentioned, from the professor himself, Mr. Brion Toss.
Also, beware of the difference between a
reduction of strength by X5 vs.retention of
strength... no big deal if it's 50% but a value
FWIW, ISAF requires radar reflectors regardless whether the boat has
radar. Even on a steel hull.

We have knots on all main and spin halyards. The boat came that way. We use
the same halyard with the roller furling headsail when cruising as we do for
Wednesday night races and regattas. The halyards are some variation of a low
stretch high tech line possibly ½ inch outer
Some radar will interfere with some other radar sometimes. The weird lines you
see do not show where the boat is. I have never seen this sailing, but I have
flying. It was a series of curved dashed lines across the screen.
AIS will be 10,000x better than any kind of radar reflector to get you
That’s one of the more weird things I’ve heard… radars are specifically
designed to try to filter out any signals not their own.
Other boats might have something like the CARD system aboard to pick up other
In USAR training (including confined space) we only used the Figure8 knot on
'life' lines. Everybody knew how to tie and untie, so there were no surprises.

the radar antenna is a good sized metal construction. It will reflect. Also,
since it is tuned to the same (about) frequencies, it can passively re-radiate
some of the signal.

I had two bad ones also. Kidde sent me two new ones, and info to return
the bad ones.

I had two Kidde brand extinguishers on the boat and both were confirmed to be unsafe for use. The company is sending two new extinguishers along with disposal instructions for the old ones. The old ones were from 1985 and 1996.
Reflection is only effective if it reflects back to the radar transmitter.
Curved surfaces don't work very well and a flat surface will only work if
it is perpendicular to the incoming signal. That's why most radar
reflectors are 3 flat surfaces at right angles to each other. They are
In my case I am using 3/8” New England VPC and the knot in attaching to snap
shackles for spin, and two genoas. And attached to a locking pin shackle for
