Bungee cord stock ???? (for the rudder hold-down lines)
Where do you get some of that?? Or do you just cut the hooks (ends) off the long ones??
More importantly, when you pull your rudders up, do you just add some "fun" to the exercise ??
I find it a bit of a pain just using regualar rope material...

We use the Duane Dunn rudder line fastening method rather than shock cord in the line. It's pretty simple, really, and works great.

Pull rudder "down" line through the cleat eye and hold firmly.

With the other hand, pull the rudder "up" line taut and wrap it around the cleat below the horns tightly twice before cleating it off.

This puts the rudder "down" line compressed between the deck and the "up" line coils like a brake rotor between two pads. When the rudder strikes an object, the "down" line overcomes the friction and pulls the excess line from the remaining loop through under the cleat.

It does NOT pull the rudder back down once past the obstruction and a rudder in the horizontal position in the water has tremendous loads on it. Some see this as a disadvantage to this method because the rudder can break from this. Some of us don't, because you'll feel it right away in the steering and can address it by pulling the "down" line to lower the rudder again. It also doesn't keep the rudder forced down into a longer obstruction like shock cord would.

Different strokes for different folks.

In all my posts and reads on this board I missed this elegant method of holding the rudders in firmly, while providing a safety in case of hitting bottom

Hats off to you Duane - clever "mod"

Boater's World & WM both sell high quality black bungee cord by the foot, without hooks - DON'T try to tie knots - use "hog hings" user crimp on to form eye like splice- same as on factory made up bungees ..
NOTE using bungees only for hold down side ... ....on the LIFT line I have block shackled to rudder at lift point and regular (but slightly smaller ) line for easier lifting ... one end of lift line attached to eye , other run thru cleat-eye .. lift rudder by pulling line from aft of rudder , then cleat.
Recommend using those new-fangled cleats for bungees . worlk much better for hard-to-knot and cleat stretchy cord , plus can be cleated with one hand.. All these ideas are already described in Mods Pages .

It's interesting that a 10"x30" fender has about 1 cu ft of volume and approximately 60 lbs of bouyancy, while a 6"x23" fender only has about 1/4 of that, roughly the 15 lbs of a Type II PFD. Perhaps having two large fenders up high over each side of the aft berth might be a good thing for adding support of weight aft.
