Perhaps global warming by prop-equipped fish?
this has been done on 12-meter (former AC class) yachts as well, with some solutions dividing the rudder in more than two sections....
Now, this is funny, I have to participate, bear with me! ;) As a matter of fact, travelling wave propulsion has been used for many years, we...
it's a good thing that bearings weren't around when fish were invented... Imagine a fish with a prop shaft, we would never have learned about...
Did that fishing line survive? :)
Thanks Roly, much new stuff to read now... :) bye Hans

So 45 kgs it is. I have the old rules laying around somewhere, from the times it still was 30 kgs. 45 kgs from the masthead of a mast at a bit...
The rulemakers wanted to define a maximum endplate effect, which means that the effective aspect ratio of the mainsail cannot be increased by ever...
Hi Roly, could you please give a link to a web resource describing these props? bye Hans

I'm voip'ing two separate ways: the ADSL router in my office handles phone calls via the internet, the protocol is the one my ISP made available,...
Stephen, the flow field around the keel causes a downwash in the streamlines aft of the keel, ie. the flow will be a bit diverted to lee. For...
actually, for modern hulls (separate spade keel & rudders) you should design for some slight weather helm when sailing upwind. The reason for...
in the minitransat class (6.5 lwl/loa), there's a rather simple rule about stability: with the boat heeled at 90°, stability must be enough to be...
