I am confused about the definition of the Transatlantic speed record.

The transatlantic record was done on Mari-Cha IV's (M-C4) schedule.
They waited until the weather looked like it was as good as it was going
to get.

The second record was set as part of a race. The organizers picked the
time of the start. The race may have imposed some rules (maximum sails
on board, etc.) that the first record try would not have had.

Hope this helps,
