CrewWatcher is an app-based crew overboard alarm system that is the fastest way to rescue a person who is overboard. The system works like a virtual lifeline and is made up of two components: a smartphone application and a small beacon that can be comfortably worn by each crew. The beacon does not require complex manual activation. The alarm will trigger automatically in a Man Overboard (MOB) event. Should someone go overboard, after sounding the alarm, the app will automatically provide lat/long coordinates of the MOB event, the time of the event, and will visually guide the rescuer using the virtual MOB compass.

Unique CrewWatcher Features Include:

  • FREE App operates on most smart phones or tablets & is easy to use
  • No mobile service required
  • Automatically updates with new features (both App & beacon)
  • One smart device watches up to 5 crew members
  • Perfect also for children, pets, a towed dinghy or bilge alarm
  • Activates with water immersion OR separation from vessel
  • Rescue: Shows crew overboard bearing, plus distance & lat/long coordinates at point of loss
  • Bearing adjusts as boat moves and “MOB Compass” points to location
  • 30x faster response than Personal AIS Beacon at 1/3 the price

Imray Charts

About Imray charts
Imray chart coverage is divided into several series which are shown on the chart index. 
Northwest Europe, C charts provide general scale coverage with plan insets at larger scales: Y charts and the 2000 series small format chart folios offer larger scale coverage.
Mediterranean, G and M series provide general scale coverage with plan insets.
Atlantic and Eastern Caribbean, Imray-Iolaire charts A, B, D, and E series provide general scale coverage with plan insets.

Sheet sizes
C charts: 787 x 1118mm (31” x 44”)
All others: 640 x 900mm (25” x 351/2”)
2000 series: A2 590 x 420mm

Imray charts set the standard for the leisure sector with award-winning cartography which features our distinctive colour scheme, coloured light sectors and fine overprinted latitude and longitude grids to make plotting easier.

 Our charts are quality controlled at all stages of production. Based on up-to-date official hydrographic surveys, they receive continual attention and amendment by our staff, who monitor corrections to ensure that our charts are always as correct as possible when dispatched. 

All Imray charts are now based on WGS 84 datum. Apart from some of the Imray-Iolaire charts of the Caribbean Sea, all are metric.

Every chart includes details of the datum and projection on which it was based, to allow it to be used safely with GPS navigation systems.

Imray charts have been awarded official MCA (Maritime and Coastguard Agency) recognition for use on Code vessels and fishing vessels under 24m in length. 

Charts are correct to the date of printing and are supported by corrections which may be downloaded from this web site until a new edition is compiled. Once a new edition has been published the old edition cannot be corrected, is regarded as being unsafe for navigation and should be replaced.

Correction notices for individual Imray charts may also be downloaded from these pages.

Digitally printed on waterproof paper
Imray charts are now printed digitally on published on Pretex, a partially synthetic paper, which folds well and is durable in damp conditions. It may be drawn on in both soft pencil and ballpoint pen.

Imray charts are normally published to an approximately A4 fold format in a wrap around cover and supplied in robust PVC wallets. Flat sheets are available on request.

Just as the Astra IIIB has become world famous as the premier low cost metal sextant, the Astra III Professional Model with its low cost, high accuracy, and excellent handling qualities is destined to be the standard for professional seamen.

Its construction is similar to the Tamaya sextants in that it has a bronze arc fused to an aluminum frame. The bronze arc can be manufactured to a higher tolerance than aluminum, which gives the sextant higher accuracy. At the same time the aluminum frame keeps the over-all weight low enough that fatigue is not a problem as with a solid bronze or brass sextant. Nevertheless, the additional weight of the bronze arc adds about 8 oz. and gives the instrument an excellent balance and 'heft'.

The handle is a new more comfortable design, and has an electrical outlet suitable for powering accessories. Except for the weight difference, accuracy, and handle improvement, it is exactly the same sextant as the basic Astra IIIB, and has all the attributes of it. These include thoroughly tested mirrors, maintainability, and the ability to quickly and economically change the horizon mirror type.

The sextant comes with a 3.5x40 telescope and wooden case as standard equipment. Optional items include a 7x35 telescope, zero magnification sight tube (see page 11), a practice bubble horizon (see page 13) which facilitates effective back-yard practice without the need for a sea horizon, and a more expensive Professional Artificial Bubble Horizon. This provides a 2X power artificial horizon for use on land, or at sea if extremely calm conditions exist and the natural horizon is not visible. It connects to batteries in the handle for night lighting, and incorporates a dimming rheostat for use with faint stars. Shipping weight includes all accessories which are ordered from this page.
