Last year Gardens' mainsheet was rigged through a single block with a becket on the boom and a fiddle block on top of the centerboard case. A spring prevented that fiddle block from flopping around when there was little or no tension on the sheet.
That feature worked well. However, I had no way to sail without keeping a firm grip on the mainsheet. Sailing all day with a firm grip on the mainsheet resulted in serious cramping of my hands. The fiddle block, clearly, does not have a built-in cam cleat, and I did not include a cam-cleat in last year's temporary set-up.
High on the list of upgrades was a fiddle block with a cam cleat. Naively, I figured I could just swap out the new fiddle block for the old one. The two blocks are significantly different in size and, as I soon learned, the new block would not fit the spring. I searched for a suitable spring (local hardware stores, Amazon, McMaster-Carr, Grainger, etc.) without success. Without a spring - or something - to hold the block upright, the block will flop around noisily, bang up the top of the CB Case and generally be annoying.
A possible solution presented itself while I was cleaning out the garage a couple of weeks ago. Moving a collection of long unused pool noodles (we don't have a pool...), I wondered if a piece of pool noodle might work to hold the fiddle block upright. Well, in the shop, it does! A 1" slice of noodle (with a slit cut to facilitate installation) does just what I need it to do: hold the block upright and allow the block to move as needed. A couple wraps of tape secures the slit (electrical tape may replace the current masking tape...).
The block will soon be installed on the CB Case top.
Almost ready for sea trials.
