Here’s a typical though over the top response to foiling from the mainstream surfing world. Incredibly dangerous, someone is going to die, think of children, etc … that’s a long way from etiquette concerns for co-existing!
A problem we run into in our local is there are very few breaks generally and the only foil-friendly ones tend to also be the beginner spots. So on small easy days, there can be uncomfortably close quarters, where safety becomes an issue, as there’s people bobbing in every direction, clogging the peak, and nowhere else to go.
The beginner break is also the only spot where SUPs are allowed and there’s also some longboarders who chase it – and they figure they are the royalty of the kook break (versus not being able to crack the lineup on the proper break). We had an “amusing” etiquette incident where one of these longboarders took off and a foiler dropped in the same wave but about 100m down the line (and keep in the foiler is a 25 year local, the longboarder maybe 5). The longboarder was standing in the pocket going about 3mph on a knee high wave, and spent the entire ride yelling and screaming about priority rules and respect. Meanwhile the foiler never got closer than 100m and was doing mach 2 down the line cutbacks and re-entries. Etiquette breach? Maybe, but it’s a stretch. Afterward, no matter how politely and then impolitely we tried to reason with the logger about being able to share the limited waves as long as no one is affecting anyone else’s ride, to him we were all just “an army of geek foilers”.
