Ugrib and all the other forecasts use the GFS forecasting system so all the forecasts will be very similar depending on which "run" they are currently using.

I have found uGrib to be excellent and you simply aren't going to get any better as the weather systems moving in off the Atlantic are most difficult to predict how fast and in what direction they will go.

For short range, Met Eirann is great for inshore but the shipping forecast is still my choice for finding out the sea state.

For long range I can't recommend anthing better than uGrib but if you aren't busy, feel free to check out my Weather Portal which lists the best of Marine and general weather forecasts. There are plenty of marine forecasting sites there to keep you going.
