I would like to know where the calculations for
anchor sizes came from,
Is there a formula specific for
anchor size to
boat,
How do they
work out what size is needed for a
boat,
Windage by weight by size by area facing the
wind, ??????
Its so variable,
I used to install concrete
panels, a 20
knot wind and a 20 ton panel is near impossible to control,
Over a certain wind strength, the crane wont
lift, Its too dangerous, It can blow the crane over,
Its not a very high wind strength either,
Its about 35 knots and no crane will
lift any thing,
My boat has a front of some 14 feet x 10 feet, Approx, Plus
mast area,
Thats a lot of flat area to be hit with a wind, Any wind,
So how is it calculated to say in a 50
knot wind what size anchor is required to hold the boat steady in one spot and not drag,
Being in a Marina or protected bay in high winds is not an answer,
Other than what manufacturers recommend for their anchors,
I have not seen any where how they calculate that out,
