How can I stop the galvanic action I suspect is causing the delignification of the surrounding wood? More zincs, or no zincs?

Ask Sail: No-Go Engine

by Nigel Calder, Posted October 1, 2012
My Catalina 40 has a Westerbeke 42B diesel engine with less than 800 hours. After a head-gasket repair, the engine was put back into the boat...

Ask Sail: Centerboard Corrosion

by Don Casey, Posted September 27, 2012
After I fix the pin and remove the rust, what product do you recommend to protect the steel before I reinstall the board? The boat is sailed in both fresh and salt water, and is stored on its trailer.

Ask Sail: Sailcloth Woes

by Win Fowler, Posted September 20, 2012
Do you know of a process that could reduce the stiffness of my sail? I have been told I should try lazyjacks, the Dutchman system or in-boom furling, but none of these appeal to me.
Ask Sail: Another boater we know treated his prop and shaft with a zinc spray paint (93 percent zinc) that he bought at Home Depot for $10. The zinc spray sounds like a good deal, but before using it I want to know if there is any downside?

A Staysail for Racing

by Win Fowler, Posted August 27, 2012
Ask Sail: I own a 1973 C&C 30. It came with a staysail, which I have never flown. We typically use a mainsail, jib and spinnaker. We race frequently, and I am wondering if the boat would be faster with the staysail on.

Isolated Prop Shaft

by Nigel Calder, Posted August 25, 2012
Ask Sail: I have installed a shaft-saver coupling on the prop shaft on my sailboat and have realized the shaft is now isolated from the ground. Is this a good thing, or should I put a grounding strap on the coupling?

Boom Modification

by Win Fowler, Posted June 14, 2012
I have a 1968 Bristol, and the mainsheet block is fastened to the boom with a swivel on a threaded bolt that fits into the boom end-fitting, which also serves as the attachment point for the outhaul. I cannot find a replacement for the fitting anywhere, and it is showing its age. Any ideas on where to look?

Slipping and Sliding

by Don Casey, Posted June 13, 2012
Will adding a flattening agent to a glossy two-part topside paint make it much less slippery? I would prefer not to add an abrasive antiskid medium to the paint.

To Freewheel or Not

by Nigel Calder, Posted June 12, 2012
I sail an S2 8.7 with a Yanmar 2GM engine. When sailing, should the prop be locked or should I let it freewheel? If I should lock it, is it better to put the transmission in forward or reverse?
