because that will make the boat heel more due to increased drag, increased weight aloft, deviation from the perfect wing shape, reduced speed etc. and all that when the furler
is working perfectly.
Dashew didn’t buck traditions, he ignored racing
rules that restrain functionality, comfort and speed.
To get that much roach, you can't have a normal backstay. Dashew's boats mostly have B&R rigs, AFAIK, which bring other disadvantages.
Yes, a roachy full battened main is about as good as it gets.
However, in-mast furling mains are not necessarily terrible:
That's a Halberg Rassey 50 with the new Selden carbon furling mast
In-mast furling mains are cut flatter and you have more control over the foot when reefed, so in strong weather
, on the contrary, you will have less drag and heeling than a normal main.
is the main drawback of in-mast furling mains, and that's a function of less roach and flatter cut. You notice this a lot in light weather
(why I wouldn't want in-mast furling for a boat used for coastal sailing, and/or in mild latitudes), but for windy latitudes and ocean sailing the disadvantages are not really noticeable and the advantages are significant.
with our in-mast furling main and do pretty well. We beat a great lot of boats with roachy full batten mains, especially when it's windy.
