INTRODUCTION
The RYA Training Almanac Background Information
The RYA Training Charts and the supporting Training Almanac cover a fictitious area of the world. The coverage of the charts displays some of the land mass of three countries. The northern area of the chart covers the Northern Territories which includes the islands within Beaufort Bay. The time zone for the Northern Territories is Universal Time (UT), zone 0. The Northern Territories also has Daylight Saving Time (DST) as noted in the tide tables within this Training Almanac. The Southern Peninsula, on the southern section of the chart, has a -0100 time zone (to convert Southern Peninsula time to UT, -1H); it also has its own SPDST as shown on the tide tables. The Neptune Islands have the same time zone (-0100) and SPDST as the Southern Peninsula. Whilst the Northern Territories and the Southern peninsula have the IALA buoyage system (region A) the Neptune Islands have the IALA buoyage system (region B).
Victoria, which is situated on the west coast of the Northern Territories, is the primary standard port on which the tidal stream atlas and tidal diamonds are based. The tidal stream floods from the NW of the area towards the SE along the Lawrence Channel. The so-called Northern Current is said to curve offshore north of Point Victoria; therefore any effect of an ocean current has been ignored.
CAUTION
The navigational information in this Training Almanac has been prepared from the RYA Training Charts. These charts represent an entirely fictitious area of the world. Consequently, the Training Almanac cannot be used for any actual navigational purpose.
