26. Boat Diving Etiquette, Marine Mammal Protection Act of 1972 and Sea Hunt – It’s Still Alive – The Aquanettes

In this episode we discuss boat diving etiquette, the Marine Mammal Protection Act of 1972, and Sea Hunt – It’s Still Alive – the Aquanettes.

Boat diving is fun and convenient. Boats however are small and move around a lot and can present some challenges. With a little common sense and etiquette you can make it enjoyable for everyone. My number 1 rule for boat diving etiquette is to follow the boats rules even if they do things differently than you are accustom to doing. Be mindful of your gear. Don’t spread it around. Follow the boats procedures for getting in and out of the water. If you want to do something different – just ask. Remember you are not just a paying customer on the boat you are also their guest.

The Marine Mammal Protection Act of 1972 was signed into law on October 21, 1972. This act called for the protection of marine mammals with a moratorium on taking and importation of marine mammals and marine mammal products. It also called for the protection of marine mammals from commercial fishing operations and mandated the development of commercial fishing gear to eliminate harm to marine mammals. This law also established the Marine Mammal Commission and the Committee of Scientific Advisor that are both still active today.

The Aquanettes is an episode from season 4 of Sea Hunt and aired on March 25, 1961. In this episode Mike is training 3 women “Astronettes” who are going on a mission to Venus. A little bit of science fiction for Sea Hunt. One of the women has some problems and panics a couple of times underwater and it causes a fight between two of the Aquanettes. Mike breaks up the fight by throwing them both in the water. One of the women decides to go in on her own to make up for her panic attack. Now Mike and the others must find the missing Aquanette. Sharks are in the area and causing a problem with the rescue. Mike is ready to fight off the man-eating shark with a knife but ultimately uses a spear gun to save the day. 

24. Travel Insurance, Wind Power in the US and Scott Carpenter – Astronaut and Aquanaut

In this episode we discuss dive travel insurance, the current state of wind power, and Scott Carpenter – Astronaut and Aquanaut.

Who doesn’t like a great scuba diving trip? As we know, we need to plan our trips well in advance and in many cases make a significant investment. Things happen and we should really protect that investment with trip insurance. There are a number of products out there to insure your dive travel. Divers Alert Network and DiveAssure offer a variety of products that cover single trips or annual trip insurance. You can check out these options on their websites.

2019 was the 2nd warmest year on record. No doubt that carbon dioxide is contributing. Wind power is a great option to help reduce emissions. You can gain a great deal of information on the state of wind power in the United States at the American Wind Energy Association web site. In 2018 wind energy reduced 201 million metric tons of carbon dioxide avoided the equivalent of taking 42.7 million cars off the road. Wind energy is part of the solution.

Scott Carpenter was one of the original Mercury 7 astronauts and he was also a pioneer aquanaut. His book that he co-authored with his daughter details his journey. He joined George Bond as part of the Navy’s saturation diving program and participated in both the Sealab I and Sealab II projects. His 30 days underwater on Sealab II was a record for living underwater. After his diving career was finished he rejoined NASA and was instrumental in the development of underwater training to simulate being weightless. Scott Carpenter was a true American hero.

In this episode we discuss Sink the Stink, 4Ocean, and Your Next Dive takes you to Atlantis Dive Resort in Dumaguete Philippines.

Sink the Stink is our go to product for cleaning our neoprene wetsuits and boots. The product is based on technology developed by Bob Denton based on work he had been doing for the oil and gas industry to remove contaminants using bacteria. As an avid diver Bob realized that there was an application for using bacteria to clean wetsuits. The technology is based on good bacteria in Sink the Stink eating the bad bacteria in the neoprene that causes the bad smell. A little bit of Sink the Stink goes a long way in cleaning your gear. Check out Sink the Stink.

4Ocean is a global organization based on optimism with a single purpose of ending the ocean plastic crisis by cleaning the ocean and coastline and stopping the inflow of plastic by changing consumption habits. It was founded by two friends – Andrew Cooper and Alex Shulze who were disappointed with the amount of plastic they encountered on a trip to Bali. Their response was to establish a business model where they would sell bracelets and pledge to remove one pound of trash for each product purchased. It is not a non-profit organization and does not accept donation. 4Ocean is a making a difference. Find out more at

The Atlantis Dive Resort in Dumaguete is located about 300 miles south of Manila – a short 1 hour flight from Manila to Dumaguete. The resort is located on a private beach in Dauin – 30 – 40 minute ride from the airport. The rooms are very nice with either a king size or two queen beds, a couch and desk. Some rooms have double sinks with a walk in shower. Toko Restaurant is where you will take your three meals featuring an ala carte breakfast followed by a blackboard menu for lunch and dinner featuring soup, salad, up to four entrees and dessert. The diving is close to the resort with 10 minute boat rides. The biodiversity is outstanding. With trips to Apo Island to see amazing coral diversity and Oslob on Cebu to snorkel with whale sharks you won’t be disappointed. We are looking forward to our trip in 2021.

In this episode we discuss our time at DEMA, clothing made from recycled plastic, and another installment of Your Next Dive – Little Cayman.

Our three days at DEMA was packed. We had a chance to meet with all of our partners, look at new products, research various travel options, talk with organizations involved in ocean health and sustainability and meet some interesting people in the dive community. We talked to Autumn Blum –  founder of Stream2Sea, Bob Denton – the inventor of Sink the Stink, Cathryn Castle Garcia – executive editor of Dive Training Magazine, and Stuart Cove. We also had a nice chat with Zale Parry of Sea Hunt fame.

Clothing made from recycled plastic sounds like a great idea. On one hand it is taking plastic out of the ocean but at the same time may be putting it back in a different way. Turns out that synthetic fibers shed when being washed and produce microfibers that can’t be filtered out in our treatment plants. There are two different types of fabrics that are being made that if washed properly will result in positive outcomes. The two fibers are Repreve and Econyl. Some options to reduce microfibers include hand washing, using Cora balls, Guppyfriend washing bags, or a Lint LUV-R washing machine filter.

If you’ve never been to Little Cayman – get there. If you’ve been there before I am pretty sure you’ll want to get back there soon. The Little Cayman Beach Resort is a top-notch resort with great rooms, a fantastic all-inclusive dining facility and large pool and bar area. You can also relax in a beach-side hammock. The onsite dive operation – Reef Divers run 4 – 46 foot Newton dive boats that accommodate up to 20 divers. They are truly valet diving that get you to Bloody Bay Wall quickly. The diving on Bloody Bay Wall is some of the best I’ve encountered.
