Is it cheaper to bring docks up to high surge standards or to install
good storm moorings?
The answer is if you live in a coastal area both the docks and mooring have
to be designed to high surge standards. While at mooring the vacated docks
may break loose and damage boats.
Inland the design may be less rigid
Our docking system is made of 8 feet wide X 16 feet long sections,
I got the corner brackets made of 1/2" thick cold rolled steel. Holes were
not punched but drilled. The 90 degree bending was done on a progressive
press. All steel brackets were checked for bending cracks and faults.
Our mooring system consist of 1" OD + heavy duty chain at the bottom and the
top section is made with 1/2 - 3/4 OD chain. Attached to the top is a 5/8 -
3/4 OD three strand rope. Some boat have two pennant others prefer having
only one.
As for the exact scope of chain and pennant including the weight and shape
of the mooring block you can refer to the Power Squadron standard or the
Army Corps of Engineer. Other have better systems and may tell us about it.

Assume well maintained screw in type moorings and well maintained
docks. Assume sufficient length of mooring pendants for surge so as
not to hit other boats.

An additional question:
