[Rhodes22-list] Center Board Questions and pics

[Michael D. Weisner]

Ric,

As an original owner of a 1981 Rhodes, I can say that without a doubt, the
hose installed by Stan was simply garden hose, probably a cutoff from the
hose used for the cb pennant tube.  They kept our cb in place for over 30
years without problem, although I did not launch with the board down
(although I often recovered to the trailer with the cb down to engage the
underwater guides).  Make sure that the stainless tube inside the cb is
still there to engage the grooves in the cb trunk.

The line was 1/4" braided nylon.  The original was blue.  Never use twisted
nylon.

The blocks provide mechanical advantage to reduce the effort required to
bring up the 80 lb cb.  I believe the standard arrangement used 2 blocks and
achieved a 4:1 advantage.  There are diagrams on the site to help, a few of
which are included at the end of this posting for your convenience.

If you need help, I am not far away (as long as it is before Memorial Day).

> I removed the CB cap last weekend and found some interesting  issues.
> The crack had been there for some time, but started leaking badly  mid

> I have attend some photos to augment this  discussion.
> I appears the crack in the cap was caused by the board swinging  too 
> far forward, so the top forward edge of the CB was forced into the 
> cap.
> It happened before I inherited the boat and it was "repaired" with 
> silicone from underneath.
> The two blocks under the cap are bolted with long  #10 screws from the 
> bottom and covered with silicone from the top - its ugly  and wrong.
> The two blocks attached to the CB itself appear to be for 1/4  line, 
> and need to be replaced no matter what.
> The system line in my system  was 1/4 nylon twist,  and much too 
> stretchy.
> So here are some  questions:
> 1. What size and type line is ideal for the CB system?
> 2.  Where can I find those blocks that fit in the slot in the CB?
> 3. What stops  the CB from swinging too far forward?
> 4. The tubes, (pieces of hosing)  appear to be clear hose - they may 
> have shrunk, or were cut short on purpose,  but are an inch short of 
> the cap, and one is very warped - what are they  supposed to be made 
> of?
> 5. What is the proper installation for the two  blocks attached to the 
> cap?
> Thanks in advance
