Always know the state of the tide at your local spot. My handmade West coast of Ireland slate tide clock will make sure that you always know if the tide is high or low,rising or falling.Set it once and it keeps in harmony with the tides so that you never make a mistake with the state of the tide on your local beach or marina, slipway or pier. This particular clock is 250mm x 250mm and is made from a piece of black slate recycled from the roof of an old west of Ireland cottage.It comes with a wooden spade hand. The slate face of the clock is engraved and then drilled and a sturdy nautical rope is attached to allow the clock to hang safely and securely. The end result is an item that will look well in any surroundings, whether above a fireplace in a cosy coastal cottage or on a wall in a corporate boardroom.As boating gifts they are truly well received and can help transform any room to a nautical decor theme. My handmade tide clocks are ideal tools for fishermen,sailors,surfers,kite surfers,kayakers,dog walkers,horse riders and anyone that uses the coast for pleasure or profession.They make a treasured house warming gift for coastal residents and great gifts for boaters. Tide clocks are easier to understand than tide tables. They run on moon time and instead of revolving every 24 hours,they revolve every 24 hours and 50 1/2 minutes.Along the Atlantic, where the tidal cycles are regular with two high and two low tides during each day, the clocks rarely need adjusting.They can be used on all Atlantic coasts in Europe and the East coast of the US and Canada. The clocks ship with full, simple to follow instructions and Looney Creations swing tag with the words "Who knows what the tide may bring!", I am happy to customise a clock especially for you.Please contact me and we can work it out!
