Tender Plan
The Ship's Launch
Since Anjumal will be our home, our tenders will be our cars. Our plan
is to cruise extensively. We would like to anchor Anjumal in a safe place
when visiting an area, then have a seaworthy tender that we can use to make
comfortable day trips to the surrounding areas. These long trips may
include guests, scuba gear, and picnic supplies. We wanted a large
comfortable tender that had good speed, a seaworthy ride, range for a day.
We also wanted diesel power so we could fill it from our main tanks.
After
a great deal of searching we narrowed the choices to Novurania and Nautica I/O
tenders. At this time we are planning on incorporating the
Novurania Custom 6 meter.
The large, open fore space will accommodate a number of passengers for a short
trip or a lot of gear for a longer trip. The fore space will have an
insert that can also turn it
into
a lounge to sun-bath while stopped in an out of the way place. It has a
walk through to the stern and a large boarding deck at the stern. We'll
have a hand rail and scuba tank storage on the platform, as well.
These purpose-built tenders come with lifting eyes for the crane and retractable
cleats and lights for a low profile on deck. The 50 gallon fuel take will
give us plenty of range for a day.
Launch & Tender Crane 
The down side of the large diesel tender is the 4000 pound dead weight that
must be lifted to the boat deck. This will be handled by a large
Steelhead CT4000
19' extension boom hydraulic crane. With this crane we can lift the tender and
place it in the water on either side of the ship, or at the stern. This
flexibility will help us to deploy and retrieve in the widest range of
conditions.
The navel architect has added strengthening to the aft saloon bulkhead to
support the added weight and torque from the crane. His calculations show
the inherent stiffness of the hull will keep us to a maximum 5 degree list if
the 4000 pound tender were held straight out to the side of the ship. He
also feels the additional weight on the boat deck will soften the ride a little
bit from the initial hull and we should not require any compensating ballast.
We figure this is pretty good for a 65' ship carrying a 20' tender.
The Tender
If the Novurania is our car, then the dingy will be our pick-up. This
will be the boat
we launch to take to the dingy docks, haul trash, land on the
local beach, etc. For this we have a
13' Caribe with
50 HP
Honda stroke outboard. This
gasoline outboard powered inflatable is very comfortable for short trips, uses
modest gasoline and is even powerful enough for some water skiing and water
toys. We've added a portable Garmin 276C GPS with depth finder so it can
function in poor visibility and act as a depth scout.
The Dinghy
For
back-up, the kids to use, extra capacity and special purposes we have a hard
floored 10' Bombard
inflatable with a small
9.9 HP Mercury two-stroke. Since these outboards tend to sip fuel, we will carry a small
quantity of extra gas in jerry cans in the swim platform lockers. This
dinghy can be kept fully deflated and only brought out when needed.
A Worthy Lifeboat
We put some thought into what conditions could cause us to need to abandon
ship. For many cruisers in a fiberglass hull, this could be fire, hitting
a whale or cargo container, or disastrous weather. In the case of the Cape
Horn, we don't believe the first two are likely scenarios and the weather would
have to be truly disastrous of 'Perfect Storm' magnitude. In these
conditions it is hard to imagine how to get into an inflatable, if it even works
after all the time in the container, or doesn't blow away in the storm. We were thinking about this while
visiting the shipyard and observed that the North Sea fishing fleets being
serviced out of the yard are shifting to an enclosed rigid life capsule shown in
the picture.
We found these are built by Ovatek
in the same yard as the Cape Horn 75s. A little more research found the
life-cycle cost is less than a maintained inflatable. Added
benefits are numerous. Survival gear can be kept inside, yet still be
regularly maintained. A redundant hydrostatic/manual release enables crew
to wait out a threatening situation in the lifeboat and only deploy if the ship
actually goes down.
Of course the rigidity and buoyancy of this design
makes it much more likely to survive a storm that has claimed the mother ship.
We'll mount this with the hatch just steps away from the pilot house door.
If the ultimate disaster were to be encountered, this will give us a real
chance of surviving.
