T&T: Anchor,chain,rope specs and use

[Parvey]

Hi Rob,

You don't need the surface area (which is extremely difficult to calculate,
you need the projected area. You only need to estimate the area within the
outline of the boat. This can be made up of simplified geometric shapes
(rectangle and triangles mostly for a boat). Take a look at your boat, bow
head on. On my trawler it would be best represented by a small rectangle
(house) sitting a larger rectangle (hull). If this isn't clear I could
e-mail a sketch off list.

Regards,

--Jim


"...but I still don't know how to reasonably
approximate the surface area of my boat use in the formula...especially the
pointed hull shape...
