Most committed sea kayakers are proud if they perform their first roll. After the very first, another rolls come easier, until the kayaker figures out that the roll is just in a single direction, on one side, usually the strongest side. Then the whole process starts once more for the off-side roll. Eventually, the roll on either side gets good. But a collection up roll doesn't mean that a kayaking rovaniemi can roll when something happens unexpectedly. Usually, the very first few necessary rolls are blown, until the renewed rolling practice starts incorporating more unexpected obstacles to rolling back up. More practice in more difficult scenarios then leads toward a "bombproof" roll.
