Are there any favorite companies for sunset cruises, and in particular, do any of the companies stick to the Grand Case/ Anse Marcel / Marigot side of the island? I am particularly interested in those with a private charter and not a big group. Pyratz's Cocktails & Tapas tour sounds good but I think they go from Simpson Bay to Mullet and back.
Also, does anyone have experience using Calypso for a private shuttle between SXM and Anguilla? We are considering this as we have a day trip planned to Anguilla. Thanks in advance for any tips / insight.

(Of note - the idea here is to have a small amount of private time on the water for a short memorial / moment of silence for a loved one. We are not big boat people and not interested in spending a larger portion of the day on one of the excursion type trips).
