When we bought our Hanse 341 in 2009, my wife and I were
long term dinghy racers, but had only chartered yachts on a few occasions in
the Mediterranean and the Caribbean.
Hence being given a berth at Largs Marina was our first encounter with
finger pontoons.
The Problems
Our problems arose as follows;
·
As neither of us had that much experience of
close situation boat handling, we had decided that my wife would helm the yacht
during berthing and I would do the rope and shore work, as this fitted our
physical attributes. So, we wanted an
easy confident giving method.
·
Particularly early in the year, the east or
south- east winds can blow strongly off the hills and down into Largs
Marina. For our allocated berth, this
would mean that the winds were on our starboard aft quarter as we approached
down the main aisle and then as we turned to port it would be on our port aft
quarter as we went into the berth, pushing us into the slot and off the pontoon
as we moored port side to.
·
The yacht kicked to starboard in reverse, thus
any action to slow the yacht down would pull it away from the pontoon.
·
Our berthing partner was a posh 11m long power
boat with large flared bows, so any thought of "gently lying
alongside" and pulling the boat across was out of the question.
We tried various simple mid-spring or quarter spring
techniques, but either the stern swung away from the pontoon if the yacht was
put in reverse, or the bow blew off the pontoon as the effect of prop wash on
the rudder was small, because the propeller was so far from the rudder, so
steering the yacht into the pontoon has minimal effect. In addition, none of the techniques were
positive in guaranteeing that the bows were stopped away from the main walkway. Many Largs sailors use a shore based
mid-spring that they grab hold off from a pick up post.
Our Solution
I decided to make a combined mid-spring and stern line that
I could use as our "parking lines" which I could just slip over the
cleat at the end of the finger pontoon as we came in.

·
I made a loop of rope about 40cm dia of 10mm
rope with a small section of plastic tube (ex vacuum cleaner hose) to keep it
slightly open. To this loop I attached
two lines. (Yellow line on diagram)
·
The first line, 10-12mm thick, should not be too
elastic and is rigged so that it goes through a mid fairlead in the toe-rail
and then onto a mid cleat. This line is
marked so that it can be easily set so that when the yacht is moored at the
pontoon, it is held about 0.5m from the walkway. (Red line) (white rope in
picture below)
·
The second line, also around 10-12mm dia., goes
from the loop, under the guard-rails, to the genoa winch with one turn and then
into the self-tailer and is marked so that when taut it would just allow the
yacht to go fender to fender alongside our partner boat. (Green line)(red rope
in picture below)

So, our mooring procedure is when we approach the berth, I can stand near the shroud with the loop in my hand and also holding the line that will become our bow spring which has been looped over the yacht’s bow cleat. I step off the yacht onto the pontoon and just slip the "parking line" loop over the pontoon end cleat. If we are coming in fast (ie if the wind is strong) then the helm may apply a small amount of reverse, but then they start winching in the stern line to keep the stern near the pontoon and the yacht still moving forward. As the mid-spring line comes tight, it stops the yacht going forward and the yacht swings into the pontoon. We normally have a fender right at the bow, but I can also just move down the pontoon and steady the bow. I then normally just put the bow spring line temporarily onto the forward cleat on the far side of the pontoon to secure the yacht to act as a bow line.

We then consider the yacht "parked". Bow and stern mooring lines are looped over the pontoon cleats and made off on the yacht. The bow and stern springs are brought to the mid cleat on the pontoon and made off there. As the 2 springs cross, one of them has a plastic sleeve on it to prevent chafe.

(Note One rope to one mooring line. Fenders tied off to the base of the
stanchions, not the guard rails.)

have a detachable one that can slide on the genoa tracks. Pfeiffier marine spring cleat)

)
We may take off the "parking lines", but if it is
likely that the wind will be blowing us into the berth when we leave then I
will leave them on. To depart, we then
take off the springs and the proper stern line.
Then it is just a case of un-looping the bow line of the pontoon cleat
and then slipping the "parking line" loop off the pontoon end cleat
as the yacht starts to move back. Actually,
we often will just set the loop on the outer horn of the cleat, so it just
slips of on its own as we reverse out and the initial tension on it counteracts
the prop-walk.
When we go to another marina, we either ask the length of
the allocated finger pontoon or guess its length, by looking at other boats,
and then adjust the length of the mid-spring accordingly, erring on the short
side of course.
When we talk to other people, they sometimes seem to think
we are over-complicating things, but then you watch them either struggle to get
into a "blowing off" berth or, more likely, take the easy option of
going for a "blowing on" berth and put up with squeaky fenders and
hope the wind drops before they leave.
We are so confident, we will nearly always go for the "blowing
off" berth, and these are often the ones that have been left free.
This year’s task; practice dropping the loop over the
pontoon cleat using a boat hook, whilst I am still stood on the yacht.
Another idea is for when we have to turn round in a tight
space. The conventional idea of
alternate bursts of forward and stern power does not work, as the saildrive propeller
is too far away from the rudder. So, we
do, what in skiing terms, would be called a pre-turn.
In one harbour, we often go down a narrow channel between
the long pontoon and the shore and with the wind behind us we want to turn
round to moor up alongside the pontoon, starboard side to, head to wind.
We go down the channel and when we want to turn around, we
move to the port side of the channel at a speed of around 1kt. We then turn sharply to starboard and then as
the yacht crosses the middle of the channel, turn sharply to port. The idea is that the yacht develops so much
angular momentum in the initial part of the turn to port, that it continues
turning even when the wind starts blowing on the bow in the last part of the
turn. In that instance, a burst of
reverse at the end of the turn, slows the yacht and pulls the stern in so we
are parallel to the pontoon.
If we were just aiming to turn the yacht around in a tight
channel, I would probably go the other way round.
There are a number of charter boats near us and a common
mistake that the charterers make is to drive the yacht like they drive a
car. Reverse out, out of reverse gear,
change helm engage forward drive and they do not recognise that the yacht is still
going backwards when they change the helm and so they kill the turn too early.
