Morazan
Also known as: Ekkai Maru, Morazan Maru, SS Manco, SS Morazan
A British-built steamer of 1908 on her starboard side in Coron Bay, upturned hull at 12 to 16 m, sand at 25, and one passage running her whole length.

The dive
Descent is usually at the stern, over the rudder and the gap where the propeller shaft ran, then a short swim across the plating to a doorway. Behind it is the rear hold, and from there the ship stops being a set of separate stops and becomes one route. The 'tween decks run forward the whole length of her: down and up through the holds, past the engine room and the funnel, two more holds, and a door near the bow that puts you back outside. Ninety metres of ship, in a line.
What keeps that comfortable is a hole somebody else cut. Salvors took the steam engine out through the port hull, and because she is lying on her starboard side that hole now faces the surface. Between about ten in the morning and two in the afternoon on a clear day the light drops straight down into her and divers surface talking about a cathedral. Two boilers were left where they were. Three bomb holes near the bow are the other way in, torn open by the bombing.
Most dives finish outside on the upturned port hull, which is mostly shallower than fifteen metres and carpeted in hard coral. The bridge, the holds and the kingposts are all up there, and the funnel lies off on the sand at twenty-five, below where it stood. Razorfish gather over her in a large school, hanging nose-down and moving forward in that position, and they are the animal divers describe afterwards once they have finished describing the ship. Scorpionfish sit on the plating everywhere.
What makes it special
She was a banana boat. Before the capture, before the bombs, this hull carried fruit and passengers out of Spanish Honduras for a La Ceiba shipping family, and her maiden voyage in 1908 took her two thousand miles up the Amazon to Iquitos. She had already been through one war by then. The Royal Navy requisitioned her in December 1914 as a squadron supply ship, and from January 1915 she lay at Stornoway in the Hebrides as an auxiliary patrol depot ship1. Two navies on opposite sides of two wars is not something the rest of this fleet can claim.
The diving reason is the route. The other lit wrecks in the bay give you holds to drop into and come back out of; this one gives a passage with the ship closing over you and opening again, at a depth that leaves time to swim the whole of it. One diver who knows both put the feeling next to the President Coolidge in Vanuatu, on a ship a fraction of the size.
History and origin
She was launched at Scotts of Greenock on 27 November 1907 as the Manco, yard number 422, and completed the following year for a Liverpool owner: a steel screw steamer of 2,979 gross tons and 91.53 metres, two masts, triple-expansion engines good for twelve knots, refrigerated holds and cabins for passengers1. Divers who measured the wreck in 2006 made her 93 metres.
The name she is dived under is one she never carried. She was the Manco until 1921, the Morazan under her La Ceiba owners after that, and the Ekkai Maru from 1942, Japanese ownership having followed her capture at Shanghai in December 19411. Morazan Maru belongs to neither ship.
Her Panamanian registration in her last years is what ties the record together. The Japanese and American naval compilation of the Coron raid lists among the ships lost that day the Ekkai, ex-Panamanian Morazan2, and her builder's register closes on the same event from the other end: bombed on 24 September 1944, sunk by American aircraft in Coron Bay at 11 degrees 59 minutes north, 120 degrees 02 minutes east1. A Clyde shipyard and a naval loss list, with nothing in common, agree on an obscure change of flag three years before she went down.
For a while she was somebody else. In 2005 a researcher argued that the ship lying on her starboard side here was a captured freighter called the Taiei Maru, and the physical evidence he leaned on was encrusted lettering across her stern reading CEI, a gap, then SH. He read it as part of a ship's name. A British-registered merchant ship carries her name above her home port on the stern, and her home port from 1921 was La Ceiba, Spanish Honduras1. The letters are not another ship's name. They are her own address, and they identify her.
Divers settled the rest with photographs. Working from 1930s pictures of the Morazan, they checked the wreck against the things a camera can decide: how many portholes there are and how they are spaced, the air vents, the railings, the doorways, the davits, the mast fittings, and a pattern of bolt holes on the funnel where a letter V had been fixed, the mark of the line that bought her in 1921.
Know before you go
Book the middle of the day. This is one of the few dives anywhere you book by the clock: from roughly ten to two on a sunny day the light comes down through the salvage hole and fills the holds, and the same dive at eight in the morning is a darker and smaller thing. Carry a torch anyway, and a second one if you are going the full length, because the lit part of the interior is the part under the hole.
Wear a full-length suit, and the reason is the ship and not the water temperature. The engine was cut out with torches, the bomb holes are torn plate, and the passenger corridor on the through-route is down to its steel framework. A diver on that route in 2025 came out of it with a cut palm from one brush against the steel. Hover through the openings, and keep hoses and gauges tucked close.
Decide how far in you are going before you get in the water, and be honest about the training you hold for it. The shops here differ in what they will let a customer do inside a wreck, and this is the hull where that difference bites, because the daylight makes the interior feel like a swim through open water. Light through a hole is not an exit.
Take nothing. She passed the fifty-year mark in 1994, so everything on and in her is state-owned cultural property under Republic Act No. 10066, and disturbing the site at all takes written authority and museum supervision3. Her engine has already gone. The bottles and fittings in the holds are what is left.
Then settle the evacuation question before you book. No working recompression chamber is confirmed anywhere in Coron. The nearest chamber reported working is at Puerto Princesa, in the same province, and no airline flies Busuanga to Puerto Princesa direct, so the scheduled route runs through Manila. Hold insurance that pays for hyperbaric treatment and for the flight, and check the boat carries oxygen.
Why Dive Morazan
What makes this dive site stand out.
- Bow to stern inside her
One 'tween-deck route links the holds from one end of the ship to the other
- Daylight through a salvage hole
The engine was cut out and the hole left behind now faces up and lights the holds
- Upturned hull in coral
She lies on her starboard side, so the port hull is the roof at 12 to 16 m
- Her builder's register survives
Launched at Greenock in November 1907, with yard number, dimensions and owners recorded
- A school of razorfish
Razorfish gather over the wreck nose-down, the animal divers remember after the ship

Conditions & difficulty
Summary
Three dives share one hull. The upturned port side at 12 to 16 m is easy diving in daylight. The holds and the engine room are moderate. The continuous passage from one end of the ship to the other is an overhead commitment that wants wreck training, whatever the light coming through the salvage hole suggests.
Safety considerations
What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.
- Overhead: The passage runs the length of the ship and the openings along it are doorways, not exits. Daylight falling through the salvage hole and the bomb holes makes the interior read as open water when it is not.Wreck training before the full route, a torch and a backup, and the route agreed on the boat, before anyone is hovering at a doorway. Daylight overhead is not a way out.
- Visibility: Silt lies on the interior floors, and this is a dive whose whole appeal is the light in the holds. One fin down takes that away.Trim and buoyancy settled outside the wreck, not inside it. If a hold goes dark, the way back is the way you came.
- Structure and sharp edges: The engine was cut out with torches and the hull was holed to do it, and the three bomb holes near the bow are torn plate. The passenger corridor on the through-route is down to its steel framework, and a diver on that route in 2025 finished it with a cut palm from a single brush against it.A full-length suit, gear tucked close to the body, and no contact with the structure. Hover through the openings. Pulling yourself through one is how the cuts happen.
- Marine life: Scorpionfish sit on the wreck in numbers and are as hard to see here as anywhere else.Stay off the structure. Hover clear of the plating and do not use it for balance.
- Depth: The hull tour at 12 to 16 m and the sand at 25 are two different dives on one site, and the deeper one spends the bottom time much faster.Decide which of the two you are doing before you descend, and treat dropping to the sand as a choice you make on purpose.
- Remote location: No working recompression chamber is confirmed in Coron. This wreck takes less experienced divers into an overhead environment, which is what makes the distance matter here.Settle the evacuation question before you book, hold insurance that pays for hyperbaric treatment and for the flight out, and check the boat carries oxygen.

Regulations
No dive permit, quota or booking system was located for this wreck. What binds a diver is Republic Act No. 10066: she passed the fifty-year threshold in 1994, so everything on and in the hull is state-owned cultural property, nothing may be removed, and disturbing an underwater archaeological site takes written authority and direct supervision from the National Museum of the Philippines. Her engine has already been cut out and taken; the bottles and fittings in the holds are what is left to lose. Going inside is separately an operator rule, and the shops here put a wreck specialty behind the full route. A municipal tourist and environmental fee applies in Coron. Ask an operator what the trip price already includes.
Frequently Asked Questions
How deep is the Morazan?▾
The sand alongside her is at 25 metres and that is the number to plan against. The hull she is lying on runs much shallower: the port side, now uppermost, sits between 12 and 16 metres, and a dive kept up there is a long one in full light. Operators give an average working depth of around 15 metres, or a band of 18 to 25 if the holds are on the plan. A maximum of 26 metres turns up occasionally. It rests on one diver's computer against six independent accounts of 25, so plan on 25 and treat the extra metre as noise.
What certification do you need to dive the Morazan?▾
Advanced Open Water for the site as a whole, because 25 metres is past what Open Water covers. Operators do list Open Water for this wreck and they are not being loose about it: the coral-covered hull at 12 to 16 metres is a real dive on its own and stays inside those limits. The full bow-to-stern passage through the 'tween decks is a different question again, and the shops here put a wreck specialty behind it. A grading of moderate describes the middle of that range.
How long is the ship?▾
91.53 metres, or 300.3 feet by 45.2, from the register her builder filed when she was launched at Greenock in 1907. Divers who mapped the wreck in 2006 measured 93 metres. A registered length and a tape measurement landing within about a metre and a half of each other is unusually good agreement, and it is worth more than either figure alone, because they are different kinds of claim reached by different methods. The 95, 100 and 120 metres in circulation have nothing behind them, and one site that publishes 100 metres on its list of dives carries 91.53 on its own page for this ship. A figure of about 35 metres also circulates and is simply wrong.
Was she ever called the Morazan Maru?▾
No, and the hybrid describes no ship that ever existed. She was the Manco from 1908, the Morazan from 1921 when a La Ceiba fruit company bought her, and the Ekkai Maru from 1942 under Japanese ownership following her capture at Shanghai in December 1941. Morazan Maru welds a Honduran name onto a Japanese suffix. Almost every listing uses it and no booking has ever gone wrong because of it, but the ship on the seabed was the Ekkai Maru when she sank and the Morazan for the twenty years before that.
Why do some accounts call this wreck the Taiei Maru?▾
Because of a few letters on her stern, read the wrong way round. In 2005 a wreck researcher argued this hull was a captured freighter named Taiei Maru, and the evidence he leaned on hardest was encrusted lettering at the stern reading CEI, a gap, then SH, which he took for part of an earlier ship name. A British-registry merchant ship carries her name above her home port on the stern, and her home port from 1921 was La Ceiba, Spanish Honduras. CEI and SH are the two ends of that. The evidence meant to make her a different ship is the single strongest confirmation that she is this one. The researcher is reported to have changed his own view since, but the 2005 page is still up and still dated 2005, which is why the argument keeps coming back.
How was the wreck identified?▾
By photograph, feature by feature. Divers took 1930s pictures of the Morazan down with them and worked through a list of things a camera can settle: how many portholes there are and how they are spaced, the air vents, the railings, the doorways, the davits, the mast fittings, and a pattern of bolt holes on the funnel where a letter V had been fixed, the funnel mark of the line that owned her from 1921. They measured the hull while they were at it. Her builder's register, filed decades before those photographs were taken, gives the same length to within a metre and a half.
Can you swim all the way through the wreck?▾
Yes, and it is the reason to choose her over another Coron hull. One 'tween-deck route runs from a door near the stern to a door near the bow, through the holds and past the engine room, and a diver can cover the ship without coming out of it. That is a full penetration, and the word carries its own detail: the openings along the way are doorways, the floor silts, and the route is ninety metres long. The shops here put a wreck specialty behind it. The shorter version, in through a hold and back out the way you came, is what most divers on this wreck actually do.
