  1. It was an Enterprise dinghy and sailed sluggishly until a capsize. It would have been better left to form a nice little reef but it sank in shallow water and the owner wanted to retrieve it.

  2. The "app" for that was invented more than 2000 years ago by Han Dynasty Chinese. It's called a compass. Set the bearing you want and walk the bearing, keeping the needle on your bearing. You can get an electronic gps app to do the same. Good luck.

  3. Catching up on my science reading I found this this morning.

    Macrostomum lignano - free-living, hermaphroditic flatworm of the intertidal sand in the Adriatic Sea.is a well known lab animal. It has a duo-gland adhesive system that allows it to repeatedly attach to and release from substrates in seawater within a minute. We propose an attachment–release model where Mlig-ap2 attaches to the substrate and Mlig-ap1 exhibits a cohesive function. A small negatively charged molecule is secreted that interferes with Mlig-ap1, inducing detachment. These findings are of relevance for fundamental adhesion science and efforts to mitigate biofouling.

  4. This morning I'll be fitting a spreader boot. The opposite side boot is taped around and around the spreader and has lasted for years. So I'm hoping for recommendations for anti-UV tape, or the best adhesive tape for the job.

  5. Straight slot. No feeder. Goes up pretty well in the calm so I'm guessing the sizing is right. I tried loops around the bunt and foil as I raised every metre or so to keep the bunt from blowing out, but the pressure was still too great in the small amount of sail exposed to the wind. I thought of wool loops but haven't tried them. I'll try the downwind option.
