How to reduce rocking?
 

Binaries (pictures) are a no-no!

I've got one of those in my van, and it's a pain in the neck. It pulls in
fine, but it takes wrenches and profanity to get the "clutch" to release so
you can (manually) pull the cable back out. I'd suggest a come-along.

Get two of those for $39 And they will more than do the trick.

You don't want to tie off to the dock hard enough to prevent rolling.
You'll break something.

Get a couple pieces 3/4 inch plywood 2 to 4 feet square (depending on
size of boat) and embalm in epxoy. Drill holes and make a bridle for
four lengths of rope coming together so that the sheets are held flat
when suspended by a single rope. Attach a heavy weight to one side of
each plate. Then weight the opposite side so that it just barely
sinks level when lowered into the water.

Tie one of these to amidships cleat on each side. When the boat
rolls, the weight heavily weighted side will let the plywood tip and
sink easily. It will then be pulled flat on the return roll. With
one on each side, there will be enormous roll damping. The weights
should be heavy enough that you can just lower them to the bottom and
tie the ropes off when leaving the slip.

One of these bow and stern will also damp pitching. A refinement is to
incorporate those dockline snubbers into the side of the bridle
opposite the heavy weight to soften any slight shock.

Harry,
Are you trying to destroy an honest to goodness real boating thread? Let's
keep it to your OT cut and paste threads.

You might look into these:

http://www.slidemoor.com/

Two of each might do the trick. You could use the slidemoor on one side
and tie tight to it and run tight lines to the tideslide on the other
side.

There is little more ironic on the internet than "Christian conservatives"
trying to figure out what Jesus would do and then claiming their behavior
towards those who need help fits that model.
Modern "conservative Christianity" is the antithesis of what Jesus taught,
conflicting biblical passages notwithstanding.

How to reduce rocking?
 

I agree about not tying off too tightly - not only will that put a large
strain on the whole system, it will be very uncomfortable on the boat, with
lines snapping taught and jerking the occupants every time the boat tries to
move.

I preach the antithesis: long lines, which can then be gently tight but will
still have lots of elasticity to make a less fatiguing motion.

Reducing the motion by other more elegant means will then of course be
required.

I'm thinking about springs. Something about 150 lbs. That shouldn't
be enough to make anything break, but enough to keep down a
lot of the motion. I was thinking of tying up solid with wire rope on
the inside--the direction the waves are going--and then using the
springs on the outside. And it can hit bumpers on the inside finger
if the waves push it that far, hopefully so it can't over stretch the
springs. Some of these look like they might work:

but are longer than I want. I believe I want something about 6" if
possible.

Oh hehe, why didnt u say so in that case ya like what you said would work
with like pivots

I keep off the beach that way, by staking down a gang plank. The boat floats
in about a foot of water, saving the bottom from rubbing against the sand and
rocks for days at a time. But that's hitting the rear end of the boat, and these
waves are hitting the starboard side. Then again, the gang plank is staked in
sand but this would be steel to steel.

but also what you could do is why not just some good ol
wire rope, measure what u need to make it nice and tight and get some loops
of wire rope made put them on crank it down and ur set it wont come loose
and there is nothing to worry about...

Maybe wire rope and springs. That's what I'm thinking about right now, but
haven't found the right ones yet. Maybe 150 pound springs about 6" long
on the wave side, and maybe on both sides, with wire rope to attach it.

Or the other thing u could do is get
two cheap winches from Harbor Freight install them on the deck of your house
boat and have a loop in the end of the wire rope and put them over the
cleats at the pier and winch your self nice and tight to the pier and u
could do the same for where ever your house boat travels take u.

Joe

It seems like that might cause something(s) to break.

The sell rubber stubbers that help to absorb the shock of waves on the lines
and boat hardware. They can also reduce the rocking while in the dock.

Do it in the back seat of the car in the parking lot and not in the boat?
