When a Board meeting is held and a motion is voted on the Captain
called for aye votes and did not called for opposed votes. She moved
on to other business.
Is this a correct procedure?

First, you'll need to know the bylaws which govern your meeting.

Roberts Rules of Order are the near-universal basis for meetings,
and bylaws frequently incorporate them by reference.

These were written in the 1800s and are surprisingly relevant today.
A few versions are available in paperback books, and online.

One thing to note is that these Rules include a phrase to the effect
that when circumstances arise that are not explicitly covered in the
Rules, commen sense should be used to arrive at a satisfactory
procedure.

These URLs are for Roberts Rules sections related to voting, and they
always describe asking for "No" votes as well as "Yes" votes.
