Being able to hoist the entire sail with just one big pull was quite a difference from the 33sqm masthead asy on my 14

It's lucky the 470 was so stable, symmetrical kites on a really tippy boat (cherub, 14 etc) must be a total nightmare.

Gybe mark, Cherub worlds, 1976. Incidentally that worlds was one by an Australian sister and brother, Nicky and Julian Bethwaite.

If your class rules allow it try a flying pole on a symetric. On our Javelin (sailed on a small pond) I,as a little old man had great trouble clipping the pole onto the mast with 15 sm of kite flogging on the other end, so I converted it. Much quicker. We sold the "Jav" and now have a Taser so we dont have to bother with all that nonsense.

small ponds are where symetrical spinnakers rule, as the wind bends through the trees you can sail your best course to the next mark without worrying about gybing angles in the same way you need to with an assy
Feeling sorry for vegans since it became the latest fad to claim you are one

Not all chemicals are bad. Without chemicals such as hydrogen and
oxygen, for example, there would be no way to make water, a vital
ingredient in beer.

As more evidence here's another Cherub archive pic. In this one, as you can tell from the shadow, the pole is a couple of feet off the forestay...

Syms are even better for narrow rivers.

Also for the kind of tidal waters where you often want to run deep just off the beach to keep out of the current. All that gybing in and out with an asymetric, not good. Salcombe, Cowes, Burnham are the sort of places that is an important factor.
