To comply with the current European standard EN 1972 (2015), a snorkel for users with larger lung capacities should not exceed 38 centimeters in length and 230 cubic centimeters in internal volume, while the corresponding figures for users with smaller lung capacities are 35 cm and 150 cc respectively.[3] Current World Underwater Federation (CMAS) Surface Finswimming Rules (2017) require snorkels used in official competitions to have a total length between 43 and 48 cm and to have an inner diameter between 1.5 and 2.3 cm.[4] A longer tube would not allow breathing when snorkelling deeper, since it would place the lungs in deeper water where the surrounding water pressure is higher. The lungs would then be unable to inflate when the snorkeler inhales, because the muscles that expand the lungs are not strong enough to operate against the higher pressure.[5] The pressure difference across the tissues in the lungs, between the blood capillaries and air spaces would increase the risk of pulmonary edema.
“A tropical sea, sandy beach and palm trees - this is written in a home page of Tropical Island. OK - there si no sea, just few pools with sweet water - 2 inside and L outside (in the winter time), wild river outside. In pools some atrrcations for small kids and some tobogans. most areas are tropical plants and trees, shops, automats, restaurans. Small part of area is wellness with some sanunas, possibility of massage(for extra payment of course). Sauna rituals are abut nothing . You will not receive towel , you must bring your own or pay for 3,5EUR to rent. You have to pay for lockable cupboard - capacity for 2-3 peoples (winter time). Sandy beach - sand was cold and wet. On the other side I must say that environment was excellent. Ok - my opinion - it wasd very nice to see this, but this is not aquapark , just overpriced botanic garden. My opinion is based on the experience of visiting in the winter.”
An hour before, in a maze of punch-colored lockers, I located number seven-thousand-something and began shoving all signs of winter weather into it. Puffy coat, recently unwound scarf, thick socks, boots, and sweater all went in, but not before I removed a bikini and beach gear from my overnight bag. An hour outside of Berlin, Tropical Islands (T.I.) fills an airfield hanger originally built in 1938 for the Nazi Luftwaffe. The Red Army overtook the site in 1945 and the Soviet Air Force stayed until 1992. A Malaysian company purchased the hanger at a steep discount in 2003, after some kind of German cargo-blimp enterprise went bankrupt. T.I. opened a year later.

Snorkeling is simply swimming along the surface of the water and looking down at the oceanic activity below you. No special skills or training is required, and the equipment needed to do it is minimal. Scuba, or SCUBA, is an acronym for Self Contained Underwater Breathing Apparatus, which is the pressurized air tank you need to wear as you dive well below the surface. It’s what allows you to be fully immersed (both literally and figuratively) in the ocean life around you. It’s a more extreme experience, and as such, more training and equipment are necessary.

Swim Slowly! Exhaustion is a common problem for first time snorkelers. Swimming takes a good bit of energy. The trick with snorkeling is to stay relaxed and calm. You can wipe yourself out quickly if you are not careful. Only swim at a speed that allows you to breathe slowly and easily through your snorkel. Your snorkel does limit your breath, so keep your activity level at a pace that does not demand heavy breathing. Your fins will make it much easier. Learn to just float without effort. Only swim rapidly if necessary for safety.
1938: First swimmers’ mask with integrated breathing tubes. In 1938, French naval officer Yves Le Prieur introduces his "Nautilus" full-face diving mask with hoses emerging from the sides and leading upwards to an air inlet device whose ball valve opens when it is above water and closes when it is submerged.[18][19][20] In November 1940, American spearfisherman Charles H. Wilen files his "swimmer’s mask" invention, which is granted US patent 2,317,237 of 20 April 1943.[21] The device resembles a full-face diving mask incorporating two breathing tubes topped with valves projecting above the surface for inhalation and exhalation purposes. On 11 July 1944, he obtains US design patent 138,286 for a simpler version of this mask with a flutter valve at the bottom and a single breathing tube with a ball valve at the top.[22] Throughout their heydey of the 1950s and early 1960s, masks with integrated tubes appear in the catalogues of American, Australian, British, French, German, Greek, Italian and Spanish swimming and diving equipment manufacturers. Meanwhile, in 1957, the US monthly product-testing magazine Consumer Reports concludes that "snorkel-masks have some value for swimmers lying on the surface while watching the depths in water free of vegetation and other similar hazards, but they are not recommended for a dive 'into the blue'".[23] According to an underwater swimming equipment review in the British national weekly newspaper The Sunday Times in December 1973, "the mask with inbuilt snorkel is doubly dangerous (...) A ban on the manufacture and import of these masks is long overdue in Britain".[24] In a decree of 2 August 1989,[25] the French government suspends the manufacture, importation and marketing of ball-valve snorkel-masks. By the noughties, just two swim masks with attached breathing tubes remain in production worldwide: the Majorca sub 107S single-snorkel model[26] and the Balco 558 twin-snorkel full-face model,[27] both manufactured in Greece. In May 2014, the French Decathlon company files its new-generation full-face snorkel-mask design, which is granted US design patent 775,722[28] on 3 January 2017, entering production as the "Easybreath" mask (see Figure 3) designated for surface snorkelling only.
