Roger,

Have I ever mentioned how cool I think your boat's name is? After seeing
tons of "Wave Dancer's" and "Sanctuary's", I really appreciate a boat
name that has obviously had some thought put in to it. Yours shows a LOT
of thought.

Hi Bryan,

The below enclosed post regarding the trailering tie down procedure we
use on Dynamic Equilibrium was originally written about 1-1/2 years ago.
 There are also a couple of attached .jpg photo files.  On the bow
photo, note the use of the extra tiedown strap backing up the trailer's
winch.  Once the bow of the boat is solidly winched up against the
trailer's V-shaped rubber bow stop and that backup strap is attached,
there is no way the boat can move backwards on the trailer.  There will
be a little "adjusting" or shifting around as the boat & trailer come up
the launch ramp out of the water.  This will happen automatically as the
boat's weight goes from being supported by the buoyancy of the hull in
the water and changes to fully be supported on the trailer's bunks. 
However, since both the hull and the trailer's bunks are wet and
slippery, this shifting around does not hurt anything.  The bow of my
boat ends up solidly against the V-shaped bow stop on the trailer
recovery after recovery.  It's foolproof.

Note, Dynamic Equilibrium's trailer is a Lil Dude tandem axle model. 
But, there is no reason why this technique will not work just fine with
your single axle trailer as well.

Try it, you'll like it!

Hi Everybody,

A couple of days ago, somebody asked how to safely tiedown their R-22 to
their trailer.  The two attached photos show how we do it on Dynamic
Equilibrium.

Up on the bow, we use two extra tiedown straps.  One tiedown strap backs
up the trailer's winch.  This tiedown strap gets attached to the bow eye
as soon as the bow is winched up against the trailer's V-shaped bow stop
while the boat is still in the water.  That way, the bow is held solidly
against the V-shaped bow stop and there is no possibility of the
trailer's winch coming unlatched & allowing the boat to slide backwards
off the trailer while it is being pulled up the launch ramp.  The second
tiedown strap prevents the bow from rising up or sliding forward under
heavy braking.  This second tiedown strap is not attached until the boat
& trailer are ready to hit the road.

At the stern, we also use two extra tiedown straps.  Note how these
tiedown straps attach onto the transom lifting eyes and crisscross under
the hull before attaching to a pair of stainless steel padeyes bolted to
the trailer's frame.  This crisscross diagonal tiedown arrangement note
only secures the stern from rising up or sliding backwards, it also
prevents the hull from shifting side-to-side.  Note the use of four IMCO
F13180 plastic anti-chafe pads at strategic points to protect the hull. 
These two tiedown straps on the stern are normally the last things to be
secured before the boat & trailer are ready to hit the road.

All of these pieces/parts are available from West Marine.  Note: You
might need slightly different length tiedown straps &/or padeyes to fit
your trailer because my trailer is a Lil Dude tandem axle model, not the
OEM Triad model.  But, the basic strategy should work as well on the OEM
Triad trailers as it does on mine.

It's a pretty quick & effective tiedown system.  We have a lot of
launches/retrevals and thousands of trailering miles on ours.

Hopefully this answers your trailering tiedown question.  Enjoy!
