Is it possible for an anchor to glide out from where its dropped in for a 5-1 scope? SAIL magazine''s New Gear section said that the Flook Anchor, an 11-pound pantograph (?) anchor does this, making it possible to set a second anchor or to kedge without moving the boat or launching the dinghy or walking it out, for that matter, I suppose. Its a bit pricey at $94, but sounds great, especially for those times when I run aground and can''t wait for the turn of the tide. Anyone have any experience with this?
