RYA Handy Racing Rules
Handy Racing Rules is a quick reference tool for the most common Racing Rules of Sailing, a mobile application equivalent to the very popular RYA Handy Guide. The text for the Rules Dispute Best Practice from the RYA is also included. All rules shown are referenced against the ISAF Racing Rules.
Racing Rules is part of a series of RYA applications developed in partnership with Imray and Tucabo. The Imray Marine Navigation series covers an extensive range of reference material useful to leisure sailors, fishermen, surfers and people involved in sea water sports. The Imray Marine products are intended for quick reference and learning.
Beautifully illustrated with diagrams and short, clear text. Quickly check and remind yourself about racing rules, right-of-way, room, penalties, signals and protest procedures.
– Right of way
– Conduct of the race, starting

Tide Graph HD
Tide Graph HD uses the harmonic predictions from thousands of US coastal stations and presents them in a fun and interactive graph. And now, in version 2.0 you also get an intuitive graph that shows sunrise, sunset, moonrise, moonset, and moon phase at a glance. Save recent locations, find locations using GPS location, and save graphs for later.
Tides have a great influence on the lives of boaters, fishermen, surfers, coastal communities, marine life, and vacationers just to name a few. Directly or indirectly, the great flow of our massive ocean bodies of water impact the daily lives of everyone on this planet.
The cyclical movement of the Earth’s tides are caused by a combination of the gravitational forces of the sun and moon as well as the shape of the costal region. Unlike simple tide clocks that you can buy in novelty stores, more accurate tide predictions use special data gathered by instruments located at each tide station. The data from these measurements are used to determine the harmonic components which then feed into the mathematical algorithms which predict tides for the future. The end results are tested for accuracy and adjustments are made as necessary.
Tide Graph has US owned Tide Stations Only. An internet connection is required to get the latest tide graph. – See TideGraph.com for a complete list of stations.
