PN Singapore to the Philippines

Few boats attempt to make this passage without stopping as there are a number of convenient ports on the north coast of Borneo. A passage during the SW monsoon offers the best chance of favourable winds, but such a summer passage also carries the risk of typhoons as one approaches the Philippines. Typhoons, however, are less frequent in the southern half of that archipelago so one should plan on restricting one's cruising to that area during the critical period. There would be less risks from typhoons if the passage is made during the NE monsoon, but then the winds will be mostly contrary. As the route runs along the coast of Borneo, the voyage can be interrupted in any one of the three states bordering on the South China Sea and there are several ports in Sarawak, Brunei and Sabah where yachts can find good shelter.

and proceed to the western quarantine anchorage. Because of the heavy amount of shipping, it is essential to time one's arrival for daylight hours.

There are two variants which can be sailed on this route. Having left the Strait of Singapore through the Middle Channel, from WP PN441, the more northern route (PN44A) runs between South Natuna and Subi Kechil islands to WP PN442. From there, a course is set for WP PN443, south of Luconia Shoals.

The alternative route (PN44B), also leaving the Strait of Singapore at WP PN441, goes first to WP PN444 by passing south of a group of small islands, the closest of which is Pulau Kajuara. From WP PN444, the course turns NE and goes through Api Passage, NW of Borneo, to join the other route at WP PN443, south of Luconia Shoals. In all these passes attention must be paid to the currents, which can be very strong at times. Another hazard along the north coast of Borneo are the various oil plat

From WP PN443 boats bound for the Southern Philippines can set a straight course for WP PN445, 12 miles S of Melville Island at the entrance into Balabac Strait. From Balabac Strait the route enters the Sulu Sea, where conditions can be quite rough during the NE monsoon. This is one of the reasons why the inside route through the Sulu Sea is not necessarily the best if bound for Luzon and Manila. Ports in the Northern Philippines are better reached through the Palawan Passage, as described below.

Boats bound for ports in the Northern Philippines and intending to use the Palawan Passage, should
