Re: Cal 21 Owners
Well, they say it is always best to go back to the source for questions<GRIN!>
On the KEEL PLUG, most of it is wood, the JENSEN Marine/CAL original was (believe it or not) Mahogany. Any stable hard wood should suffice, pine might work, but may be too soft and swell too much.
The main body of the plug (lower plank?) is one piece of wood, the hinged flap is a second piece of wood, the amgled plate at the forward end is metal, we used Stainless Steel (about 1/16" -3/32" thick), but brass or steel could be used (steel will rust, but maybe if it was galvanized it would last longer) I wouldn't use aluminum (except maybe on a trailer-stored boat due to electrolysis. The vertical rod is metal, we used steel because we had some available, and added a short piece of brass at the top for hte wingnut that secured the plug to the keel well cover. CAL originally designed the plug with 2 bungee cord lengths to hold everthing together, but it did not restrain the plug from working up and down while sailing and so the rod was substituted (I think that was a modification sent out by CAL, but I'm not sure.
OH, and when inserting and removing the keel plug, it helps to tie a lanyard to it since ours tried to float away one time when my Dad dropped it (after a full 6-month sailing season o na mooring... the keel plug had absorbed water and was almost neutrally buoyant).
