It's something lots of sailors don't understand. Your sails
are supposed to be wing shaped so that they create lift
and minimize drag (same for the keel
which balances out with the sails to create that forward vector). The best wing shape is elliptical and the full-batten bat-wing shaped main sails as seen on Dashew yachts, multi-hulls and most modern designs in general, come closest to that optimal shape. Check out the shape of the main on a racer
Any diversion from this shape means you get less lift and more drag, even if you have the same, or even more, surface area.
Now here's the deal: less efficient wings make you heel instead of go forward... and this slows you down, decreases comfort and creates a more dangerous situation on deck.
Dashew yachts have way less surface area than other, comparable cruisers. This makes the sails easier to handle and by optimizing shape, Dashew gets away with that without loosing performance.
Anyone who thinks the boom angle must always be 90 degrees on a furling main simply hasn't ever used one. You can cut the sail to make the boom angle whatever you want it to be. And it only needs to be at that angle when furling. The rest of the time you can put it wherever you want, just like any other rig.
No way!!! If a furling main is cut so as to adjust the boom angle, it needs that same, static angle for all reefed positions. You always want it cut for 90 degrees because you would simply loose too much surface area otherwise. Not so for a slab reefed main which will just lift the boom up a bit more with every additional reef.
In between furling you can sure adjust boom angle up, but that is clueless because it will only make the sail baggy, heel you more, which is exactly what you don't want when the going gets tough. You want the sail flat as a blade and the end of the boom pointing up simultaneously.
Todays boats are not designed to prevent rolling to the point that the end of the boom touches the water
in a wave. That's just wishful thinking.
And about learning to sail, I agree that people should learn to do it the "right" way first. But that's not what you said. You said it was EASIER to learn slab reefing than furling, which isn't true. So who's turning things upside down?
I did not say that at all. I said it was the PROPER way to learn it
Earlier I talked about a guy that starts furling straight after stepping aboard from his RV. That didn't indicate any learning at all, which is what I often see hopping by (clueless "sailors" that are trying the "cruising" thing after last years RV'ing and without any sail-training whatsoever). These are the guys buying
the boats and getting the issues with the furler
as mentioned by WaterwayGuy.
I have no problem with people who love their in-mast furling or even with that system itself; I only have trouble with people saying that it is the better/superior system for modern boats. Many believe that because when "it comes out of the mast automatically
", it must be way more advanced and better than the old system. That's just not true and I will keep telling that.
