Background information and definitions
Vessels can impact subtidal benthic invertebrates through disturbance to the seabed and water flow(Hammerstrom et al. 2007). Setting limits on hull depth of vessels (recreational or commercial) entering an area may potentially reduce disturbance to subtidal benthic invertebrates as the hull would be further from the seabed and less likely to result in direct physical damage from collision, grounding, or in changes in water flow or sediment transport (Whitfield et al. 2002).
