Stop stirring. Spring tides happen twice a month all year round. Nothing to do with season. A synonym for jump, burst forth, rise. So new and full moon, when gravitational pull of sun and moon align. Neap tides are the opposite, when moon & sun are at right angles and partially cancel. Spring tides result in high waters that are higher than average, low waters that are lower than average, "slack water" time that is shorter than average, and stronger tidal currents than average. Neaps result in less extreme tidal conditions. There is about a seven-day interval between springs and neaps. 1 Quote Link to comment Share on other sites More sharing options...

A cubic metre of atmosphere weighs about a kilo at MSL. Rule of thumb is that a change in air pressure (density) of 1 hPa (hectoPascals or millibars in old money) will alter the sea level by 1 cm. The convention is that tide tables are drawn up with a standard pressure of 1013 hPa. So if the air pressure is 1043 hPa (High) then the sea level will be lower by 30 cms than expected by your tide table. If it's 993 hPa (Low) then the sea level will be 20 cms higher than expected. That's how a combination of a deep low storm with high winds coupled with spring tides can devastate the East of England. UK air pressure has been recorded at 925 hPa to 1050 hPa but with global warming who knows...? Best leave it there before I turn into a tidal bore... Incidentally this "summer" has seen a low pressure system crossing the UK for the last seven weekends. Better make the most of this one... 1 Quote Link to comment Share on other sites More sharing options...

Kipper99 Posted September 4, 2023 Share Posted September 4, 2023 On 8/23/2023 at 11:16 AM, Andy Onchan said: Kipper Please explain what is meant by this "These have created a sense of distrust between officers and crew "? And.... Are you seriously suggesting that crew have a say on "Manoeuvrability in harbour in windy conditions". Surely the Master is the final arbiter in such a situation? Interestingly, the SPCo aren’t mythbusting 1. 40% higher fuel consumption. 2. Harbour manoeuvrability issues due to increased windage. As for the point you raise Andy, the modelling tank exercises and computer simulations, before build was started demonstrated these. They were shared with crew ( masters, bridge officers and engineers are crew ) and they raised their concerns. They were, and still are being, ignored. That was the start of the industrial relations down hill slope resulting in the industrial action ballot. Other matters were the covid crewing debacle and the attempted unilateral steam packet management attempt to breach the staffing agreement dealing with how long on/off and living on board. 1 1 Quote Link to comment Share on other sites More sharing options...

Blade Runner Posted September 4, 2023 Share Posted September 4, 2023 The new boat weighs nearly twice what the Ben does. It is also quite a bit longer and 3 meters wider, with much more of a slab side elevation to catch the wind. I wonder why it is using 40% more fuel per crossing as Kipper99 says?
