RIGHTING THE BOAT
The trimaran setup of the Tandem Island makes it
extremely stable and nearly impossible to capsize under
most conditions. However, unexpected events do occur,
so it is important to know how to “right” the boat if it
were to turn upside down.
Step 1. Remain calm
and stay with the boat.
Step 2. Because it
is so stable with the
amas in the “out”
position, you will need
to unlock both of the
aka crossbraces to fold
them in. You should
also attach the Bungee
that holds the amas
in to keep them from
Step 3. Reach underneath the boat and make sure
the mainsheet is uncleated. It will make it a lot easier
to right the boat if the sail is loose and free from any
Step 4. Climb up on the hull and reach around to grab
the midship carrying handle or one of the aka bars.
Holding onto that grip point, lean back to apply your
weight to turn it back over. It is important not to pull
hard quickly, but to pull with a constant, steady load.
Step 5. As it rolls back up, watch for the boat coming
over your head. Once the Island is upright, roll up
the sail and fold out both amas so you can climb back
into the boat. Hang onto the boat at all times so it
doesn't sail or drift away from you"
The manual for the Single Island actually has more pictures in the same
righting' section - maybe have a look there as well - link: http://2010.archive.hobiecat.com/suppor ... Manual.pdf
