Moderate sounds ok dosn't it? It means swells of up to 3mtrs (10ft)

I'm only ever confident in going out in "smooth" seas in my 165 , that's swells up to 1mtr , slight is up to 2mtrs , but all these figures are academic because you can go out in a slight sea when there is no wind and ride swells all day like you are on a perpetual shuggy boat which would make me feel sick but not in any danger whereas on the other hand you can go out in a smooth to slight sea with a bit of wind blowing wind over tide and the swells in a different direction again and the boat can be all over the place , dosn't make me feel sick , but the "other" cheeks can start to clench a bit.
I look at 3 or 4 different weather pages on the internet and make my mind up from them , I take more notice of the wind speed and direction than the sea state , if it's blowing more than 10mph westerly I'm concerned , if it's blowing 10 mph easterly I don't even bother.
Of course all the weather websites in the world can't beat a look at the sea in person on the day , sometimes it is flat as can be when it's been forcast slight or moderate , other times it's the other way round .
Even when the sea looks spot on , I still check the weather sites and if they say it might get rough later , I don't go very far.
Without actually going down to the sea and looking , tomorrow looks like a no go by the weather sites , westerlies turning north and too strong for my liking in the morning , easing a bit in the afternoon ...... think I might go trout fishing
