(machine translated in 2021) origin
Bought 2nd hand in August 2014, sail was 10 years old but has been rolled up in a surf shop for almost all those 10 years, had only been used a few times, perfect upgrade/renewal for my old9.5.

Different, very different
You expect 1 year difference to make little difference. No, then. The 2004 R-Type is very different from the 2005.
Split-Cams vs Roller-Cams, so Splitcams rotate very nicely, but I think they are less stable. Rigging is really easier with the hard Roller-Cams, Those split cams always shift and also the straps that are in them sometimes go loose. The slats in the 2004 are still glass, my 2005 had carbon in the longest slats, I want to test that in the 2004.
The dimensions are also very different: 2004 vs 2005
Luff: 530 vs 540 cm
Tree: 257 vs 244 cm
So the 2005 is narrower but higher. Especially that longer boom you feel in the 2004. Much more power/pressure.

On the water, the 2004 feels heavier. More power. Think mainly by the boom length. But the belly is less clear, I think the combination split-cams and glass slats make the sail flatter without wind in it. In hard gusts, the pressure point is not so stable. After a few times, I'm not friends with it, not like I was with the 2005. Try Carbon slats soon.

Sold
Due to my injury and cleanup of my garage this R-Type but sold in January 2016. Didn't take everything out of the sail that was in it, but sailed it twice. Didn't feel like putting time into this anymore.

mast
I'm going to go just like my parent9.5tackle:Platinum 490with 50cm Xtender. See if that worked so well again.
