Luna is listed as a US Coast Guard inspected passenger schooner carrying 41 guests. That figure sits on Boatsetter, marketplace, and it is the only specific inspected passenger number published anywhere in the Long Island fleet. It is also the whole of the record. There is no operator website, no published price and no disclosed berth until you book.
boatsetter.com/boats/qngkmcsEvery other operator in this study publishes a capacity that is an operator claim. Luna's listing states an inspected passenger capacity and attaches the figure 41 to it, which is exactly what a Certificate of Inspection does. The catch is where it sits. Boatsetter is a peer to peer charter marketplace, the number carries a marketplace label, and no certificate document is public for this boat or for any other Long Island vessel. Confirm 41 directly before you build a guest list around it.
There is no operator site to check the listing against. Price is not published. The listing asks you to message for a quote and notes that advertised rates cover up to 20 guests and include the captain, two crew and standard gratuity, so larger groups need a custom quote. Quarter day charters run 2.5 hours at reduced rates. Catering and event options are described as available, and the vessel is said to come fully provisioned with serving equipment. Ceremony provisions are not published at all.
Under sail, 41 guests is a large number for the East End. The listing describes swim floats, paddleboards and fee based towel service, which tells you the product is built around a day on the water. A wedding aboard would be shaped by the sailing, by the light and by how long the boat stays out, and none of that is spelled out anywhere. The berth is not disclosed until you book, which matters for guest directions and for parking, so ask about both early.
The 150 passenger figure attached to The Lauren Kristy comes from third party editorial, and from four independent write ups that agree with each other.
The Freeport Gem publishes $4,950 for up to 50 people, tax and gratuity included, and $55 per additional person plus tax.
Sapphire Princess publishes a capacity of up to 127 guests on its own site, and that figure is corroborated twice.
Captain Lou Fleet publishes 1 to 150 passengers for Captain Lou VII on its private charters page, first party, and the identical figure for two sister hulls at the same dock.
The Moon Chaser publishes a capacity of 200 people, first party, which is the largest of any vessel docked on Long Island.
Bay Princess II says it is licensed for 100 passengers, first party, which is the closest any Long Island operator comes to publishing a certificated number on its own site.
