If going in-hull, you can test your location
while in the water by placing a baggie of water
between the transducer and the hull. If it
works like that, it will work glued down. This
does not work if the boat is out of the water.
I shouldn't have to say that, but I will
because I have had a couple of people do just that.
FWIW, the transducer maker, Airmar, recommends
epoxy, and specifically warns against silicone.

very good point, excellent memory
actually. I did not have to be concerned
because I have an old 1974 design and the under
bottom is solid and thick
I think even a bubble
in that, and I know there are some because
there was one beside the hole I cut to do the
through hull mount, which may have had
something to do with why it was not always
reliable so you always have to find a spot when
there are no voids in the solid lay up too, but
at least if it doesnt work you can move it
fairly easily and you dont leave a gaping hole behind. I got lucky first try

Hi Dwight,
Don't these inside hull installations need to
be in a solid layup area and not a cored hull area?
I seemed to remember that detail being part of
past discussions on this subject.
Cheers, Russ

Based on my experience, I would say if its a
depth transducer install it on the inside of
your hull and either dont cut a new hole or
plug the one you have already. Find a nice
spot on the inside, close where you want it
located, clean the area with solvent, let it
dry and then apply a really generous gob of Dow
Corning silicone sealant and submerge the
active face of the transducer in it while
holding on a slight angle to make sure you
dont trap air bubbles, then press it down hard
and hold there for a while. I did it that way
based on information I got from this list
because my Raymarine depth transducer was not
reliable
it has worked flawlessly to over 200
feet (my boat draws about 6) for over 2 years
and I have one less hole in the boat
I am happy

Good evening. I AM HOPING TO INSTALL A NEW
THROUGH HULL TRANSDUCER this weekend. What marine sealant would you suggest?
Thank you.

I tend to agree Dwight.
That's a gripping video and reminds me of a
very similar situation I got myself into last
year minus the crushed legs. I was being too
aggressive, boats touched and although no
protest came of it, I was at fault and should
have bailed when I was getting squeezed out of
the pack before the committee boat.
On the deck after the race much discussion was
held and I insisted I could not change course
for I would have rammed the committee boat but
later when the photos came out I realized I had
plenty of time to abandon the start and not look like a knob.
The point is at speed within lengths of the
line and adrenaline is up with a bunch of fast
boats a nose blow apart, it's easy to make a
decision that you wished you hadn't after the
fact and unfortunately the only solution to this is experience.
On the plus side the event was educational,
provided lively beer talk and no damage was done.

the fleet. If she went up hard she either had
to tack away or risk ramming what I think is
the committee boat. I cant tell if the
leeward boat had room to fall off safely to
avoid collision with blue without making a
collision with the boat below her, looks like
she was being taken up too. I heard now up now
up now up now up so someone on Blue knew they
were being taken up but I dont think the
helmsman or the crew acted soon enough or fast
enough. The helmsmans effort to steer up
seemed ineffective, not much of a rudder on
that boat if you ask me. The mainsail trimmer
tensioned for more close hauled course and
looks like the jib trimmer did the same
seems
like the crew did not know how to sail that
boat under those conditions in close
quarters
they did not appear to know what to
expect from the boat and the crew
if I turned
the wheel that aggressively on my 35 I feel
certain she would go up, now I have to try that
to find out for sure and ruin a perfectly nice
beat some day. Havent raced in a while

After the preparatory signal (boats are now
racing and must sail by the racing rules) but
before the starting signal, the leeward boat
can sail all the way up to head to wind. After
the starting signal, she cannot sail higher
than close hauled. Boats must still avoid
contact if at all possible. Crossing the
starting line has no effect on how rules 11 and 14 are applied.

Alan,
Does Dave Perrys 2016 RRoS book clarify the
difference, if any, between before the start
and after crossing the starting line regarding Rule 11 and 14?
It has been a while since I read Daves last
RRoS book but I recall something about the
right-of-way boat having more flexibility before the starting gun.

Subject: Re: Stus-List Race Video
Blue was allowed to sail her course until she
was the give-way boat. As soon as she
overlapped Camelot, she was the give-way boat,
and had to keep clear. When a give-way boat is
so close to a right-of-way boat, such that the
right-of-way boat cannot turn in either
direction without immediately touching the
give-way boat, the give-way boat has violated
her obligation to keep clear. They do not have
to touch in order to prove that Blue did not
keep clear. See Dave Perry's "Understanding
The Racing Rules of Sailing through 2016, page
96. In addition, the right-of-way boat must
take the appropriate action to avoid hitting
the give-way boat, when it appears that the
give-way boat is not going to keep clear, after
which she can protest the give-way boat.
There is no requirement for either boat to
communicate with the other boat, but it is
prudent to do so. If Camelot had called to
Blue to head up, or yelled "leeward boat" or
"no room", it might have been enough to keep
the boats from colliding. If Blue couldn't
control her direction, she could have called to
Camelot to fall off, that she couldn't steer
away, Camelot might have been able to fall off
and avoid the crash. She then could have
protested Blue. Since both boats broke rules of
part 2 of the Racing Rules of Sailing
(Blue-Rule 11, Same tack Overlapped;
Camelot-Rule 14, Avoiding Contact), both boats
should have been penalized by retiring from the race (Rule 44.1(b).
