Sailing!

While transferring Constance across the SF Bay
Finally got everything fixed and set up so we could actually move the boat. The new Martec 14/14 folding prop works like a charm! At 1800rpm the boat now goes 6kn through the water, something I never was able to do with the old fixed 12/12 tri-blade, even when revving as high as 3000rpm. One downside we found out just past San Pablo point: The wash from the prop is so powerful it pushed water through the cockpit drain pipes back into the boat, and it started siphoning into the bilge. Big surprise when I looked down the hatch and saw water puddling over the floor boards! Even after turning off the engine the siphoning wouldn't stop and the bilge pump wasn't able to push against it, so the water level kept rising :-o. So for a moment I thought we had a serious issue from somewhere else, but once we started the manual bilge pump I figured it out where the water was coming from and we were able to clear all the water out. So another thing I have to update on this boat: Make sure the drain pipe loops way above the waterline to prevent siphoning, plus install a backwash valve at the pump. Other than that we managed to cross the jib and main halyards so the jib wouldn't unfurl. Need to fix that, too..
