A long shot I'm sure but.... Does anyone know where I could source the slugs that go in the boom to hold on the Gnav track? A few of mine sheared off. I tried super spars but I don't think the contact form on their website is working.
Yes, I can make new ones or possibly re-drill and tap the old ones, I just thought I'd check here in case its some off the shelf part I'm not aware of.

Thanks!

Hi Mike,

You're in luck, last year I spent a lovely few weeks tracking these down for our boat "Pretty Radical" #34.

Those are Harken item # AL-709 with a description of "SLUG-SYS A CB ROUND (H-33701A)".

To order please call 262-691-3320
Option 4.

They're a bit pricey for a piece of aluminum ($11) but work marvelously. You may want to order more than you need to amortize the shipping into a more favorable amount. We needed 2, however ordered 4. Which was lucky as 3 were the correct part, and one was a mystery slug. Harken did reship the correct size to us with no hassle.
