Had 3 days in awesome Corros conditions with the new 4.7 tiger. I'm presently on panthers and almost immediately you could tell this is a lighter sail. The sail felt neutral and effortless even in the extreme conditions we were sailing in. I was comfortable on the 4.7 when all around friends were on 4.2s. The new sail seems to have a greater wind range than the previous model. Both the 4.7 & 5.2 rig on a 400 mast all in all a fantastic sail. Can't wait to try the 5.2 in moderate conditions.
