Planing - again -yawn.

Definitely feels up over the top of the water, over the waves, level and
obviously steering easily at the high speed. So supposing that this is planing.
--------------------------------------
Could argue all day and for many days about what is and what is not
planing. Some define it as just going really fast.
However it is best just to not use the word as it does not add anything
to the discussion, just generates lots of heat and no light.
So just talk about boatspeed, preferably in knots and everyone will know
what you are talking about.

Sounds like an increase in apparent wind but could be a number of contributing factors including small reduction in wetted surface area drag. You may also be...

G'day, As well as what mark said. It is not planing, the hull is too skinny and too round. The force in the wind is a square function. Double the breeze is 4...

On Blind Date we had the rudders jamming because of the sailing loads. At first we mistook this as unbalance. By raising the front rudder board entirely we...
