I have now logged more than 66000M on my 7m40 long boat covering the British Iles, Ireland and The Netherlands round past Spain and on to Italy. Passage making or going up river till the boat grounds (at 1m) I know what I want from tide information. A weeks coefficients and H and L heights and times for the expected area are copied out on a formica board and kept at the chart table for reference at all times even when the boat is ashore for maintenance.
You have made a good start -But
- All the times should be dated unambiguously (d/m or m/d).Try a line for date as punctuation between the data blocks.
- Even the British Admiralty now use metres for depth. Remove the ft. It is just clutter and as such can only be a source of error or confusion.
- Remove the reference to the previous or next tide which is just more clutter ( and wrong see 6)). The time NOW appears at the top of the screen on my iPad. I can do the rest.
- Cut the clutter of words. HW and LW are well understood and not even needed if the data is decluttered.
- Add Tidal Coefficients. The British shun them because they are foreign but they are one of the most usefull tools available when working depths and calculating tidal stream rates.
- In the data box under Type: add the data source.

On the UK E Coast be ready a comfortable half hour before any time and watch. Rubish in a tidal stream can reverse direction without loosing speed at tide turn. Heights depend heavily on North Sea conditions and sometimes match the tabulated values sometimes. Just listen to the Thames Navigation radio for the river pilots.
Keep it simple.Just provide the numbers with their source and leave the skipper to do what skippers do.
