Anchors are very useful for inflatables anyway. I've lost them fishing my sea eagle and now leave them at home. In wind the boat would drag the biggest ones you could buy.
Sorry about your rod. I watched a really nice ultralight get kicked off my boat at lake murray once. I watched it sink into that crystal clear water for a long time. Fished for it with a slab but never got it.
You should try fishing bridge pylons. The shade is nice and most of the time you can catch some crappie. Tying onto those pylons makes for a peaceful day.
John 21:3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.
