Oggetto: Re: [Amel] boomerang davits and longer passerelle/gangplank


Hello Attilio and Maria,
Thanks for your message. One thing I forgot to mention was that we made a
new board to fit the longer passarelle. It is marine ply and to make it long
enough we added another piece attached with brass hinges on the underside
and fixed with countersunk machine screws and and nuts. Thus it folds back
and opens up when fitted in place so it is slotted in at both ends. It is
made non slip with two strips of white non slip adhesive tape running the
full length We have an elastic line to hook over the board as the first one
we made blew away one night never to be seen again.

Regards, Anne and John, Bali Hai, SM319

Hello, Anne and John, extremely grateful for the help and the very accurate

The matter to extend the passerella (gangplank) was already in my mind. Also
the matter to use dyneema and a spacer, that I already got.

Also useful the suggestion to use the red line to hoist dinghy+motor, but
normally we hoist the motor by a separate small davit on stern starboard
side. We have a 2.7m Honda dinghy and a 5hp 4-strokes Honda motor, some 30kg

Thanks a lot again, fair winds

Hello Attilio and Maria,
The gangplank is not really long enough for mooring stern-to possibly
because it was not updated when the tube size on inflatables was increased
in the late eighties/nineties. The owner of SM Galaxie increased the
by two steps and I copied him. It is supported by what we call the red
which is the one attached to the mizzen mast at the spreader on a block.
red line is dyneema and 8mm which is more than strong enough. The red line
is attached to a spacer so that there are two lines going down to the end
the gangplank via a piece of wood to open the gap between them. These
to the gangplank on U-bolts a piece of teak which is wider than the plank
and secured with saddle clips.
Our dinghy is a Honwav 30 and weighs 45 kg and this is secured to our
on 4 part blocks with a jam cleat welded on to the davit. The davit itself
is supported on 6 part tackles on blocks with jam cleats on the deck. It
hard to hoist the dinghy on these but it becomes impossible if we want to
hoist it with a 15 HP 2 stroke motor in place. However it is lifted with
great ease by by using the two red lines from the gangplank and shackling
them on to the ends of the davits which are then lowered right down to the
the blocks on the tackle and then lifting everything on the red line
by winding it up by hand on the mizzen outhaul winch or, as I am in my
eighties, on the main sheet winch.
We also use the mainsheet winch to hoist the dinghy on the red line so
we can clean the dinghy or let it down on the aft cabin top for longer
passages or over wintering. We hope this helps!

Best wishes, Anne and John, Bali
Hai, SM2K 319

Hi all,

I am just thinking to fit on my Santorin a couple of davits similar to
the ones made by a workshop in La Rochelle, and called Boomerang.

I have seen several SMs with those davits, and I know that also some
Santorins has been fitted with same davits, obviously adapted to the
different size of the stern.

Now I would like to know for a 2.7m tender (Honda) which tackles (with
triple blocks: we are getting old...) are normally used for these
davits? I think that a tackle with blocks of 45mm dia, and 10mm rope
(working load of the blocks 450kg) should be sufficient. Naturally,
triple block should be with cam-cleat.

And how long is the tackle completely closed. This is to position
correctly the holding shackle.

If anybody with a SM or a Santorin has these davits, maybe he can give
me this info/opinion?

Thanks for an answer
