Below is a screenshot of a transcription I’ve made from the journal of William Rae, who served aboard the Marquis of Hastings in 1828 in the capacity of Surgeon. A PDF of the transcription is available here.
On August 16th, Rae states that the Island of Trinidad was in sight. But having looked at the route I’d plotted and then at the location of Trinidad I realised I must have made a mistake. However, on zooming in on Google Earth I found that the location plotted for that day was near the Trindade seachannel, and having searched for Trindade, discovered that on August 16th the ship was in fact in sight of Ilha de Trindade (see image below).
