The full size chart is just a stunning bit of work. Quite apart from its practical use, it is so beautiful to look at. I just love maps and charts since I was a little child. My Dad was a ship's engineer in the 1920's and introduced me to marine charts at an early age. It is a pity that he never lived to see this chart of Lough Corrib, he would have loved it.

The Corrib Chart has made such a difference to my boating enjoyment. I need about 42 inches draft for comfort with my cruiser, and I tend to play very safe


and stick to the tried and tested routes. However, I still  got into a bit of trouble on a few occasions, finding myself over shallows that I did not expect, on the old "steamer's course."

Now, I have complete confidence to bring the boat into lovely new anchorages, little hidden bays - and I can say that 2010 was the most enjoyable season I have ever spend on Lough Corrib thanks to the new GPS system. I hope you get lots of recognition for this brilliant work. Thank you from the bottom of my heart, and from the bottom of my boat!

Having used the new lowrance version on my last two visits to my beloved lough corrib I have to say it is an absolute tribute to Trevor on his creation of the maps.They are very accurate and the depth contours leave nothing to the imagination when targeting specific species of fish. Hats off on an outstanding feat.

I've just spent a few days Ferrox fishing around Lough Corrib, the chart is quite incredible. I was able to pinpoint dropoffs which are very accurately marked, and troll along them. I'm looking forward to getting the iPad version now because I can't wait to see this on the big screen. Thanks for such an amazing bit of work!

I got the Lowrance HDS chart of the Corrib and went for a spin around Oughterard bay. It's a real tidy piece of work, well done. The contour interval is a nice touch as it shows the direction the shallows run. Some of the old markers were bent at an angle to show the direction of the shallow, your lines do that. Makes a big difference when fishing,

Just to let you know your maps are running great on memory map using an Acer w500 tablet with a GPS dongle from Maplins.

Went out on the Corrib with no problems at all and very accurate...launching a 24foot lift keel trailer sailer from Cong.

Myself and my brother found The Corrib Chart invaluable.
Not having massive experience of areas on the corrib other than Ashford castle to Inchagoill island, I was reluctant to navigate most parts of the lake but not anymore! Even at dusk when visibility is poor, it is easy to follow the route and tracks back on my Garmin unit.

Thanks  for the fantastic job you have done, you have opened up the Corrib to us all!

These below were written to me in the days when my early GPS versions (up to 1.19) of The Corrib Chart used to be known as CorribCharts. Some testimonials refer to my paper charts, others to the GPS charts of the Corrib.




The Chart is a fantastic thing to have created and is a work that will live on long after you are dead. You will join the ranks of William Wilde and Maurice Semple in Corrib lore"

"The Corrib Chart is brilliant! The charts have opened up completely new parts of Lough Corrib to me. My Garmin GPSMAP has finally come to life and is no longer a blank screen with a few black lines"

“After downloading The  Corrib Chart and up-loading to my GPS, it confirmed nicely the shallow that we discovered (by riding up onto it) during the Cong-Galway 2009 sail race on our Flying 15. It also showed us we had a number of other close shaves, that we thankfully passed over without any harm”

“As a regular user of the River Corrib, but an inexperienced user of the lake, I have found the charts on the GPS system invaluable this year. It has opened up a whole new area of Lough Corrib to be explored, safely”
- David Cox. Moycullen, Co. Galway

“After damaging two props, obliterating a skeg and having the unfortunate situation of a boat full of friends and family with my boat 'moored' on rocks in the middle (yes, middle) of Lough Corrib, all I can say is The Corrib Charts has been a lifesaver. Thank you”

"The charts are brilliant. I found a great pike location from just using the screen-shots. 5 pike in 2 sessions!"
