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.

'NE' . . .

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 !!}

If you are in the NH seacoast region .. could you tell me who, where, I
can
purchase mooring equipment.

'NE',

I go back to 'My' mooring situation . . .

The Club mooring field is also on a river with a distinct 'tidal stream' -
maybe 3kts or more. Also, when we get heavy rains this increases incredibly
and telephone poles, trees, and even 'home size' propane tanks come down the
river.

Chapman's uses as it's 'baseline' the effects on Long Island Sound {at least
my old copy does}. The Red Dragon uses Chapman as it's reference. A couple
of the mooring anchors are Railroad Wheels, literally {about 900lbs plus}.
These are 'Grandfathered' because now ONLY ACTUAL 'Mooring Anchors' are
permitted. We all use 'Mushrooms' {up to 250 pounds} because these are the
easiest to get and can be 'self placed'. {There are two other types . . .
however they MUST be 'implanted' by a diver to be effective, and also
inspected by divers to maintain their guarantees. They CANNOT be 'hauled'
for inspection.}.

For added security, especially with the 'tidal changes / reversals', many of
us use the 'Double Set'. This places one anchor 'upstream', and the other
'downstream'. While not 'rocky', our river bed is hard sand. The concept of
the 'Mushroom' is to dig the 'ring' into this type of bottom, opposed to the
direction of pull. A 'double set' also prevents 'wrapping' - where the chain
winds around the anchor and shortens itself. Eventually, 'Tide goes 'up' . .
boat goes 'down'. Or riding chain breaks and boat goes . . . who knows where
!!

Again, it is NOT the 'weight' but the direction of pull. I was think of the
'frame & concrete' idea when I first joined the 'Dragon. I was going to use
a rubber tire on a 'plate', with a heavy steel 'U-loop' attached, and fill
it with concrete & scrap wheelweights. NO WAY !! Nor the 'old engine block'
stunt, either. The 'density' changes when immersed, concrete is porous, and
iron rusts {and swells and cracks apart the concrete}.

If the 'Port' is SPECIFYING 'Granite', they should have some written
'guidelines'. These SHOULD also specify the Bottom & Riding chain sizes.
Also - it sounds like the situation is similar to the Club - YOU are
responsible for YOUR mooring. YOU own it. A 'Mushroom'
set can be hauled and 'go with you' when you leave. I doubt that several
tons of Granite are worth the cost of bringing it up. If the 'Port' requires
this set-up . . . there should be any number of 'anchors' ALREADY on the
bottom. I'd ask BEFORE I did anything else.

Just as a 'by-the-by' . . . we had a couple of Granite 'columns' {about 3
feet square by about 12-15 feet long}lying down as 'borders' on the
waterfront parking area. One of the members got the idea to set them
vertically, near the 'water edge', to use as emergency 'tie-points'
{remember what I said about the rain-swollen river !!}. He was able to get
one of the local trash-trucks {the kind with forks for lifting the wheeled
trash bins}to pick them up and move them close to the holes. Big and heavy .
.. . to us. But not big and HEAVY in your type of situation.

What, may I ask, are you paying for the chain & pennant . . . at a 'Marine
Supply House' ? What kind & size ? We usually make our own pennents.
Typically 3-strand Nylon line. Most use no, or Nylon, thimbles. I'm trying
Stainless this year.
