The outlying jetties are much like their central cousins, but sparser, more open, and more rickety. These walkways extend to the far edges of the flotilla, servicing single boats or in many cases truncating abruptly with nothing but a drop into the water. These jetties have guardrails and life preservers available in some places, but their presence (and maintenance) cannot be relied upon. There are still places to take cover, and occasional crates and barrels lying around, but these nooks and crannies are less common.
