Length should be fine - the Retro specs call for a 490 (total luff
length is 527, so you'll need a good extension such as the Streamlined
46cm one Sailworks distributes in the US: http://www.sailworks.com/web/moreinfo_1.cfm?Product_ID=109
The question then is whether the Yes mast has the right bend curve. If
it's a standard constant curve mast, it should be fine. There's an old
version of the Yes website out there (I think they may no longer be in
business?) at http://www.yes-sails.com/2004/categorie.asp?IDCategoria=2
where they talk about their masts being constant curve. The rated
stiffness certainly matches (IMCS of 29; Sailworks specs 28-30 for
this sail). If you have no way whatsoever of rigging the sail on this
mast before you buy, it seems like a reasonable risk to take, since
the Retro is a little more forgiving and less mast-specific than other
sails in this category (a lot of the tuning can be done via perimeter
tension adjustments - do a google search on Retro tuning and Roger
Jackson/sailquick, as he's given a fair amount of info on that), so
I'd say your risk of a total mismatch between your existing mast and
the Retro are lower than with most of its no-cam competitors (cambered
sails, btw, throw in another set of monkeywrenches, as you then have
to worry about mast diameter being compatible with your specific

The 9.5 Retro is a great sail, and should fit your usage pattern
perfectly. You might even want to consider going with the 10, since
it's rangy enough to bridge the gap to the 7.5 but has a bit more low-
end grunt to get you planing, but then you're looking at a 520 mast
for sure. You won't find a large no-cam out there that balances power
and control as well as the Retro (and yes, it does rig quickly and
easily). Use the adjustable outhaul (it comes with the sail, along
with instructions on how to set it up) to really get the full range
out of it; can't go wrong with it.
