Aloha Michael,
Thank you for sharing. I'm sorry the mantas were not as active on your night out with us. Each night is different and sometimes more mantas are seen at one site versus the other. Being wild animals, they have a mind of their own and come and go as they please.
The tour in which you booked was for the southern site known as Keauhou. This site is very consistent and usually has between 1-5 mantas (and sometimes more) that frequently show up. The mantas at Keauhou are super friendly and are known to come up very close to snorkelers. The Keauhou site is also conveniently located close to shore and offers a quick 5-minute boat ride out to the site. If I recall correctly your son was prone to seasickness and that is why the Keauhou site was recommended to you over our other tour which departs from Honokohau harbor. Operators departing from Honokohau harbor can visit the northern site near the Kona Airport, but this normally requires a 20 to 30-minute boat ride to get to.
The northern site (known as Garden Eel Cove) is known for having the record number of mantas seen in one given night, but it is also notorious to be hot and cold or go through periods of dry spells where no mantas are seen. The northern site is primarily used by companies taking out scuba divers and the mantas have a tendency to stay down deeper near the divers so the encounters may not be as close for snorkelers.
Each company has their own light set up. The majority of us operators use a modified paddleboard/surfboard with lights in the center and handles along the outside edges. This works well for us being that we only take out 6 guests per tour and like to keep our groups small and personal. Other companies using a bigger and more complex setup usually have 18 or more passengers that all get in the water together. Because of the large light setup they are limited to only being able to stay in a certain spot as it is difficult to maneuver a platform with numerous guests hanging onto. The setup in which we use allows us to be more mobile so that we can take guests into shallower or deeper water depending on where the mantas are feeding.
We invest in snorkel gear, wetsuits and complimentary refreshments which are all included as part of the tour. Other companies may require you to rent your own equipment, not provide wetsuits or not offer any type of drinks or snacks during their tours.
I hope this response provides you and for those reading a better conclusion of our tours and the different manta sites one can go to.
Mahalo for your time and we hope to see you both back out again.
Sincerely,
Ashlie
