Hi Ron,, .. funny, I forgot to check Chapmans and I have one on my table.
Duh?? The weight issue: the mooring is going into a river that has current. The bottom is rock, probably some sand/mud. The big issue is the current. The Piscataqua river has one of the fastest navigateable currents for rivers in US waters. Basically, where I will be moored I will only be able to leave for the open ocean or return 4 times a day. The two high tides, two lows. I think this is why the weight becomes such a big issue. I have been calling around. Granite is very dense so that a small rock can have lots of weight. I think this is another reason the port wants granite. I was thinking of making a frame, pour in concrete and also throw in some scrap metal ... make a rebar inbedded block. This would be heavy and strong. I will ask the harbor port guy what he thinks. The chaine/pennant/etc I can purchase at a marine supply house I found in the area. Saved a bundle calling them. The good thing about this is that I am learning. I always like to understand what I am buying. This way I won't get taken .. at least not much. Thanks for your input.

I'm more of a Sharp Cheese, then milk, kind of a guy . . . here is my comment on the situation . . .which hopefully is not just a 'troll'. First - How BIG is your boat to need 3 TONS of mooring ?? I have a feeling that this 'requirement' is more about the 'Granite State' then 'Chapman's Piloting & Seamanship'. The reason I mention this tome is that it seems to be the 'standard' by which any number of 'Authorities' set their Guidelines. A 'double set' I can understand, but just 'dead weight' is considered fairly low on the scale of effective 'permanent moorings'. The other thing 'Chapmans' will illustrate to you is the number, variety, and placement of the various items that make up a 'mooring'. Plus, if memory serves, advice for an inspection, 'cycle'. Which brings up another question about that Granite 'anchor'. We {the Red Dragon, one of the oldest Clubs on the Delaware River}, used to pull our entire Mooring Field annually. We now have a 3-year 'cycle'.This is so ALL of the components can be inspected & replaced as necessary. The hauling & setting is done by the Club members, with an 'A' frame & battery-powered winch on a float. With your 'required' set-up, a hired diver, or the 'mooring setter's '. Either way, a costly proposition. To be specific about the 'tackle' . . . If the 'Authority' is specifying the WEIGHT & STYLE of the 'Anchor', they should also be specifying the SIZE of the bottom chain & riding chain. If not, see 'Chapman' for guidelines. The chain size will govern the sizes of the shackles, swivels, ring, and buoy. While the 'Mooring Buoy is a 'marine item' and it's markings specified by the USCG, the rest ISN'T. This 'material' can be gotten from an 'Iron, Chain, & Hardware' supplier at $X, or a 'Marine Supplier' at $XXX++. The stuff itself can range from 'Galvanized' to Stainless Steel. Or a combination. 'We' use a local industrial hardware supplier. We pick it out & transport it ourselves. The preferred 'standard' is 'Hot Galvanized' chain & 'fittings'. My specific set-up . . . a 'double-set' with two Mushrooms {100 & 175 lbs.}, 2 - 30-foot 'legs' of 1/2in 'Hot Galvanized' bottom chain, 3/4in shackle & swivel, 32-feet of 5/16 riding chain, 3/8in swivel, and 3/8in Stainless Steel shackle, ring, buoy shackle, & pennant fittings.This is 'over-kill' for a 19-foot, 1,500 pound boat. I don't know about suppliers in NH, specifically, but check out Defender Industries {Connecticut} and Hamilton Marine {Maine}. Both have on-line sites and comprehensive 'paper' catalogs that have very good illustrations. {nice 'winter reading' as well !!} Regards & Good Luck, Ron Magen Backyard Boatshop "NE Sailboat" wrote in message news:zNhph.3181$Br.246@trndny08... If you are in the NH seacoast region .. could you tell me who, where, I can purchase mooring equipment. SNIP |
