I found Alanís comments very interesting and have been thinking about this matter since. I will not begin to dispute experience as this technique has obviously worked for Alan, his crew and others like Julian for some time. But although I donít doubt and understand the principle I canít get my head around the details?
How many of those who post on this site would be happy to go out to sea and flood their boat and be confident that there systems would continue to function and get them home? Mike?
If you decide to fill your boat you will lower its water line by? Say 100mm. Lowering the CoG by the same amount. Now I would guess that the centre of gravity for a RIB, with a console and inboard is just above deck level. By filling your boat with 400 mm of water, Will you not be placing the weight above the CoG? hence raising the boats CoG, making it more unstable. This is not to mention the effect of the FSE that can significantly reduce the stability of a vessel. When a RIB heels over the centre of buoyancy moves outboard quickly because of the sponsors. So I am unsure how this effects the standard equations concerning the FSE but I am sure it is still a relevant consideration.
As Mike said a number of offshore sailors like himself who have chosen to run before the weather. I understand that stuffing could then become a problem but is the serious of this only proportional to the speed you are travelling in comparison to the wave not through the water. So can you not reduce your speed and run at the same speed as the wave systems? Alan. Making this a feasible option.
Just a thought but this is the sort of article that would be good to see in RIB Int. They could take a RIB out in steep over falls and test these different techniques! Maybe.
