Measurements for canvas work 30' hunter

[cgreeleycoffin]

Unfortanately we are on dry dock and would like help with a couple of measurements if you have a moment?

1989 Hunter 30' -

the height from the deck to bottom of the boom.
​

the height from the helm deck to the bottom of the boom.

width and length of cockpit using coaming perhaps

any other measurements would be great to ensure size of a bimini

thanks
