Wrecks of Guam
Although Truk Lagoon, an hour and a half away, has some spectacular wrecks, Guam has quite a few also. Almost all of them are within the protected waters of Apra Harbor and all are within normal sport diving ranges.
How about a German, Japanese, and American ship in the same harbor, plus more ships, planes, and a wide assortment of barges, bombs, and
other artifacts from WWII.
TOKAI MARU
TOKAI MARU before she sank
The TOKAI MARU was a Japanese passenger-cargo freighter put in service in August, 1930. She was a "state-of-the-art" vessel, and was used by the Osaka Shosen Company as one of their modern fast luxury freighters on the Tokyo to New York City run. She was re-commissioned as
a freighter under contract to the Japanese Imperial Navy in October, 1941, and was used to transport war materials and personnel throughout
the pacific. On January 24, 1943 the Tokai was observed anchored in Apra Harbor by the US submarine FLYING FISH. Assuming that the ship
was soon to leave the harbor, the FLYING FISH waited outside the entrance for 3 days. With no movement of the ship or any other vessels, the FLYING FISH fired two torpedoes set to run at 1' depth (to cross over a very shallow reef). One of the torpedoes ran aground on the reef, but the
other struck the Tokai causing considerable damage, but not sinking her. Seven months later, the US submarine SNAPPER, patrolling west of
Guam, spotted two ships in the harbor. Not knowing at the time that these were the Tokai Maru and another damaged ship (Nichiyo Maru), the
submarine patiently waited for one week, and then made a submerged attack under the eye's of a Japanese patrol vessel less than two miles away.
At 3:23 on the afternoon of August 27th, the SNAPPER fired a spread of four torpedoes, three at the nearest ship (Tokai) and the fourth
at the other. The SNAPPER immediately headed west for safer waters. Over the next few hours numerous explosions were heard, and the Tokai
was observed with the bow at an extreme "up angle", indicating that the stern was on the bottom. A few minutes later the Tokai slipped
beneath the surface.
DIVING INFO
The Tokai Maru is a large ship, over 440 feet long. She rests in 120 feet with an 85 degree list to port (left). The shallowest part of the ship is the upper forward bridge area at a depth of 40 feet. A torpedo has blown a hole in the port #3 cargo hold, and this is undoubtedly the torpedo that sunk her. There is damage on the starboard bow, but this is believed to have been inflicted on the first attack in January, 1943. The cargo holds contains remains of truck frames, beds, scrap steel, and misc objects. The engine room is huge, and both of her engines, catwalks, and panels are intact. The after deck house in the stern of the vessel contains at least 4 depth charges, which are plainly visible from the top of the structure. DO NOT attempt to touch or move these depth charges. Visibility averages 35-40', but can vary due to the tide and large ship traffic in the harbor. A good average diving depth to see all of the Tokai would be 60-80 feet.
CORMORAN
CORMORAN at sea
The German merchant raider, SMS CORMORAN, was originally built by German in 1909 for the Russian Volunteer Fleet and named the RJASAN. She was
used by the Russians as a combination mail, freight, passenger, and cargo hauler throughout the North Pacific. At the outbreak of war with
Germany (April 7, 1917), the captain of the Cormoran, Adalbert Zuckschwerdt, scuttled the ship instead of turning her over to the Americans. 13 crew
members went down with the ship and they were buried with full military honors in the Naval cemetery in Agana. The remainder of the crew was sent to Fort Douglas, Utah for the duration of the war. They were finally sent home to Germany on October 7, 1919.
DIVING INFO
The 290' Cormoran lays in 120 feet of water on her right (starboard) side directly beside the Tokai Maru (which went down in 1943). The easiest
way to reach the Cormoran (and dive on two ship from two different wars at the same time) is to follow the midsection hull of the Tokai over
the side until you see the Cormoran at 80 feet. The hull of the Cormoran is intact. The engine room is easily accessible through the skylights,
and most of the superstructure is relatively intact. Visibility averages 35-40', but can vary due to the tide and large ship traffic in the harbor.
A good average diving depth to see all of the port side would be 80-100 feet. Visibility averages 35-40', but can vary due weather and tidal
flow in the harbor.
THE KITSUGAWA MARU
The towering mast of the KITSUGAWA
To the west of the Tokai Maru lies a third huge shipwreck, the Japanese freighter Kitsugawa Maru - another casualty of the days prior to the US invasion of Guam in 1944. Torpedoed by the submarine USS Seahorse, she was towed into the harbor for repairs and, while at anchor, was attacked by bombs and rocket fire from raiding US aircraft, finally sinking when her engine room exploded, tearing the ship in two and sending her into the depths where she sits upright on her keel at an average depth of 140 feet.
DIVING INFO
The Kitsugawa Maru is an outstanding wreck dive. Take plenty of gas (EAN 30 is the optimum choice), at least a couple of powerful dive lights
and a small reel or two if you are going to explore the quarters. Again, Professional Sports Divers runs frequent charters to "The Kitz"
on request. She rests close to the main shipping channel so the visibility can be poor and your boat skipper will need to stay close to provide
surface cover. Look for the majestic, towering mast as you descend the shot line to her deck. She is deep so your bottom time will be limited
and you need to head north-east first towards the bow to explore the Kitsugawa's most interesting and photogenic feature, the bow gun and
the four cases of ammunition that lie behind it. A stonefish occasionally lurks near the gunner's position so be careful when posing for photographs.
Returning along the deck, you encounter a section of living quarters which can be explored, but there is a lot of silt and the doors and
gangways are very narrow. Examine the holds with the bulkheads now fallen away, providing some entertaining swim-throughs below decks at a depth
of 120', but beware the tangled wreckage of the destroyed engine room. Do not spend your whole dive on the hull, however, as the mast that
you glimpsed on your descent rewards you with an opportunity to photograph or just enjoy a vibrant, colorful community of corals, sponges, anemones
and reef fish to rival the best the Truk has to offer.

Hafa Adai! Greetings from Guam, America's paradise island in the Pacific. Guam, a land blessed with a rich cultural legacy and spectacular natural
beauty, welcomes visitors with genuine warmth and hospitality. The name "Guam" comes from the ancient Chamorro word "Guahan", meaning "we have".
Ferdinand Magellan discovered Guam in 1521. The Americans took it from the Japanese at th end of WWII and it has mainly been an American Military
base since then.
Guam is the hub for a visit to the rest of Micronesia. It is at the Agana Airport where all the international planes land from the US, Japan Indonesia and Australia. From Agana, Continental Airlines flies to the other islands of Micronesia such as Truk, Pohnpei, Kosrae and Majuro, Saipan and Rota, and to Yap and Palau. But Guam has a lot more to offer than just an airport and hotels. It has some pretty good diving too.
Guam's lush underwater playgrounds sits within 50 miles of the ocean’s deepest point: the Marianas Trench, some 38,000 feet below sea level. The diving around the island is very varied. You can find nice coral gardens with hard and soft corals, vertical drop-offs, WWII shipwrecks, seaplanes, caves and tunnels.
What’s fun about diving Guam, the largest southernmost island in the Marianas Archipelago, is the variety of dives. With a large numbers of underwater species of wildlife and coral, said to double Hawaii’s count, and the varied ocean bottoms where war relics of all types can be found, diving here is always a surprise.

With Guam’s 75
dive sites, you’re sure to find one that suits your style. From walls to cliffs, to caves and wrecks, Guam won’t leave you
wanting for variety.
There are good shallow shore dives, but to avoid disturbing the reefs and to get the best view of Guam from under the surf, head out by boat.
Most boat trips take less than 10 minutes anyway.
North
It sounds like boating to the sites off the north end of the island is as much fun as diving there. Many dive operators encourage trolling
for skipjacks, or mahi-mahi in season. Tuna schools are a common sight here. Look for sea turtles, shoals of jacks and barracuda at Double
Reef and at The Pinnacle. Sand pits rest here in about 30 feet of water, interspersed with fingers of coral.
Central
Hit a central point on the west side of Guam and you’re in for calm seas. Vibrant coral greets divers along Hospital Point’s
cliff line, which opens to the ocean. Tuna, baitfish and sea fans frame the reef.
Tumon Bay is the popular tourist spot, and is sometimes referred to as an outdoor aquarium by fishwatchers catching glimpses
of Guam’s underwater wildlife. Tumon Bay provides variety within a short distance from shore.
There are shallow reef flats, patch coral, coral thickets and white sand flats. If you like to shoot photos, this is the place. An old WWII
gun provides exciting diving at Gun Beach … appropriately named.
South
Agat Bay provides some of the most popular dive sites: Hap’s Reef, Coral Gardens, Agat Beach and Shark Pit.
The Shark Pit refers more to the junk divers who find all sorts of nostalgic WWII military remnants.
As far as large fish are concerned, head to Toguan Bay for spinner dolphins in the morning and early evening, and to Shark Pit for the swarms of butterfly fish. The Bay opens to the sea allowing sharks, pilot whales, manta rays and sailfish viewing. Just off the coast is Cocos Island, a 100-acre visitor friendly, private island. Large sea-faring fish callCocos Wall, a sheer cliff, home.
Apra Harbor
Apra Harbor is a diving wonderland with its 12 official dive sites that include numerous coral reefs and WWII remnants. Divers can find a combination
of plating and branching corals here, as well as myriad reef fish and sponges.
GabGab Reef is a photography hot spot with its deep coral slopes and shelves. Invertabrates thrive here and along Fingers Reef just west of GabGab. Throughout the harbor you’ll
find staghorn coral, patch reefs and giant sponges.
The most popular dive site is theTokai Maru (see right column), a Japanese freighter sunk by a submarine torpedo attack during World War II. It just so happens that it rests on another ship, the Cormoran, which was scuttled during World War I. This is the only place in the world where two ships from different conflicts touch each other. What makes this site popular is that it’s a shallow dive with lots to see. Wildlife has taken to the hulls, one of which is about 500 feet long.
Blue Hole and Crevice
Intense water clarity makes Blue Hole a dive not to be missed. Located on the southern coast, the hole is a long, vertical shaft that starts at 60 feet and ends at 300 feet. After free falling partway down the shaft, divers find the large window to escape through at 130 feet. This dive is open to the ocean, which invites large fish such as barracuda, dogtooth tuna, eagle rays, dolphins and pilot whales to the site. If you dive here at night, the rare flashlight fish emerges from the depths of the Blue Hole. A sac under the fish’s eye illuminates biochemically and sends a flickering light to the water. An active school looks identical to a swarm of fireflies.The deep Crevice dive is a short drift away. With cooperative currents, ivers can get to both sites in one day.

Micronesia Divers Association
Locals say that although diving Guam is a year-round pastime, they agree that weather can affect the water’s clarity. Between December and May, clarity gets up to 150ft . Typhoon season, which brings the rains and wind, hits between July and September, dropping water clarity to 60ft.
The rainy season is generally from September to December. This means that a combinations of rain and sun throughout the day. The windiest
months are between January and early April when the tropical northeast trade winds are active. The calmest months are between April - August,
but since most of the diving is on leeward (west) side of Guam just about all of the sites are available all the time.
Guam waters maintain a temperature of 82-86 (28C) degrees year 'round with excellent visibility at most locations. Apra Harbor dive sites
generally have visibility in the 30-60'(10-20m) range, and all "outside" reefs offer 100-150' (33m) and more. Above water Guamanians are terribly spoiled with temperatures consistently between 75-90 (24-29C) every day!

Continental Airlinesflies daily from Honolulu, Tokyo and Bali. KoreanAir and All Nippon offer flights from Asian cities.
Plan to lose a day traveling thanks to the harsh time zone changes.
If you’re into exploring, rent a car once you arrive. Locals report that mass transit is a bust, cycling is dangerous and hitching is out
of the question. The island holds many treasures in its highlands – it would be a shame not to be able to get there.
