Thanks. Good information.

Using my 2017 Lowe 1040 the calculations come out as shown if I measure the transom width as in the graphic below. The calculations either come out conservative or over but, failing not having factory specs this may help some with older boats or those where specs are not available.

Note: The 48" measurement was taken inside the boat.
