Seabass,i think the reason is that most of these boats are for lobster fishing and not bottom fishing...if a lobstermen has to use his anchor he most likely will through it from where he hauls from and retrieve it the same as a pot...i have a anchor tee with two rollers because we spend alot of time double anchored
A couple of reasons. Boats engaged in lobstering are 'never' going to anchor during the course of the normal day (this holds true for inshore or offshore, by the way). In the unlikely event that they do anchor they have a hydraulic hauler at the ready to retrieve their ground tackle, right? Boats that lobster for a living are true minimalist affairs - if it isn't needed, it generally isn't there.
Only time I anchor it is because I'm watching the Maine Lobster Boat Races or have someone aboard who requires it. When that happens the anchor is just flung over the side and tied off to the bit on the bow. Time to come up, untie the bit and engage the hauler. Zippity zap.
I anchor up every night when i'm out on a trip (4-7 days). I just set my anchor (33lb Bruce, 40ft chain & 5/8" double braid nylon) out by my hauler once i have enough scope out i tie the anchor line to a tag line i have running from my bow bitt back to the hauler, i use a rolling hitch, then let out a little more scope till the anchor line comes tight then cleat off the anchor line by the hauler. In the morning i just untie the tag line and haul the anchor with the hauler. The beauty of the tag line is i never have to go up on the bow, i fish by myself so i'm always keeping in mind to be safe and stay in the boat.
You can see the anchor line cleated off in the picture
