Ask Sail: Zinc-Air Batteries

by Gordon West, Posted February 14, 2013
I am racing an ultralight sailboat in a three-day regatta. I am counting every ounce that comes on board, and a conventional wet-cell or AGM battery will put me over my weight limit. Is there any new battery technology I can use?
Can Pump N Seal be used to suck air out of a varnish can to stop it from skimming over?

My Yanmar 3GM30F diesel engine has about 650 hours on it, and this season, it’s been a little hard to start it. Are injectors or compression the problem?

I just purchased a 1983 Bristol 38.8 with a large sail inventory, including a nice big cruising spinnaker. Apparently the old owner flew it out of the bag, which isn’t something I’m anxious to try. What would you recommend to make the sail easier to handle?

Ask Sail: So Many Numbers

by Gordon West, Posted December 13, 2012
I recently purchased a used Hunter with VHF and SSB radios installed, both with MMSI numbers pre-memorized. To prepare for a bluewater cruise I am now installing an AIS transponder, and the technician has asked for another MMSI number. What should I do?
I have a Soverel with a small diesel engine that has sat idle for a couple of years without fuel stabilizer. The engine starts, but runs rough. There is also no discharge from the exhaust line.
