Broken gooseneck fitting
Gary, You're not alone, back in 2007 the owner of E31 hull #19 emailed me the attached image with the same fracture that he ultimately got an exact replacement for. As I see it, you have two or more options. As others have suggested, have it welded or have it recast using the old one as a pattern (very doable) or take a gamble by emailing the image of your broken one to the folks who originally made that gooseneck, LeFiell, 562-921-3411, down here in SoCal. Now, here's the catch, they have essentially gone out of the boat spar and accessory business, now turning their operation to aircraft parts manufacture. When their long time spar guy Rodney retired in March of this year, they gathered up all the boat related stuff and swept it into a corner of one of their shops with the intention of selling it all for scrap. You might just luck out by calling them ASAP to see if one of their non-marine guys could be persuaded to dig through the inventory with a print of your gooseneck in hand to possibly grab one for you. I contacted them on behalf of another E31 owner in Florida for a mast base about a month ago and came up with zip. Maybe you'll have more luck. All the best, Glyn Judson, E31 hull #55, Marina del Rey CA
