[Rhodes22-list] centerboard attachment

Ric:
What "garden hose" are you referring to? The only piece of garden house I
have goes between a thru-hulls in the cap and the cockpit and is held in
place with a hose clamps.

Hmm!
I'm very grateful for this thread and this communication.
I see this as an inherent and dangerous weakness in the boat.
I was sailing in a keel boat once long ago. We were on our way to a race in
Fisher's Island sound.
It was foggy and before GPS, we proudly knew  where we were, but not to the
nearest yard.
There are some tall rocks close to the edge of the channel in otherwise very
deep water.
There was a 2  ft chop  on a 2  foot swell from offshore and it was low
tide.
The wind had dropped off and we were moving only a knot or two, bobbing in
the bumps.
Cocky and content, alert and on watch, we were cruising along with the chute
up.
Suddenly, the boat dropped off a wave on the keel came down on a rock.  
We hit so hard I bit my tung  bloody from the impact. The mast and rigging
twanged like it broke. We quickly checked the bilge fearing the worse, but
to everyones surprise - no leaks.
An underwater inspection revealed a big dent on the bottom of the lead keel.
If that happened in a Rhodes 22, it would have driven the CB right through
the cap and flooded the boat.
No wonder Stan builds in floatation.

There must be a solution here.
What holds the garden hose in place, anybody know?
