is mainly done for fun, but competitions are also popular. Paddlers have a set time to perform as many moves as possible, and score additional points for style. Visiting a playspot where you do not need to commit to a full river run to get there (which involves shuttling cars to the bottom of the river) is often referred to as 'Park and Play'. Playboating can often be more convenient and can in some circumstances can be considered safer than river running - in particular if the play spot is in an accessible area as opposed to numerous whitewater runs which exist in remote and inaccessible (in case of injury or rescue) areas. Etiquette and culture Right of way Playboaters still generally follow right of way conventions that are commercially established. The vessel upstream of a feature has right of way over a vessel in the feature. This means that if a kayaker is surfing a wave, and a kayaker or a raft is coming downstream, the surfing kayaker should give way to the upstream paddler[s]. This general convention however is disregarded in many scenarios present in playboating: If the feature has eddy access a kayaker approaching from upstream should eddy out and get in the line to surf the wave, instead of using their right of way to catch the wave on the fly as this is seen as 'budging'. If the kayaker is approaching a play feature that does not have eddy access they do not have the right to push a kayaker surfing on the wave off. They should wait until the kayaker flushes and then proceed down to surf the wave. A kayaker may not enter a play feature that another kayaker is surfing unless they are invited on for a 'party surf'. A kayaker loses their right to stay on the wave if they stay on too long. Generally rides extending longer than 2 minutes are frowned upon and sometimes a kayaker having a long ride will be 'dropped in on'. On some rivers that are heavily commercially rafted, rafts are privileged with skipping the line because they are on a timed trip and need to hit the wave many times in a short period. On other rivers, however, rafts that claim this privilege—especially without asking the other paddlers—are heavily frowned upon. Rafts coming downstream are given right of way because they are typically less
