Prior to 1971 there was no self-bailer on the JAVELIN, only 1971 and newer had that feature. Older models had a screw-in drainplug just aft of the CB trunk to allow draining bilge after hauling boat out of water. The 1971 and newer models used the same basic bailer as is used on the SUNFISH and it has a little ball that seals the opening to prevent water from flowing into the boat...... well, ,it is supposed to, but I use the bailer on my DS II (same unit as Javelin) oly while boat is moored, not while sailing and it does prevent flooding in a rain storm (only a couple of gallons or less water stays in cockpit and that is contained in a slop-well at the stern.
But, again, the JAVELIN did not have a bailer prior to 1971.
NEWSAILER, are you referring to the floorboards in the cockpit when you talk about "teak decking"? I think another JAVELIN owner recently made new floorboards and posted pictures and dimensions on this web site or perhaps it was another. I'll look to see where I saw them.
