Fins add 0.95 m/s to overall speed, whilst Ultra Glide Fins add 1.9 m/s. Currently, the fastest way of traveling is the Seamoth at ~12.7 meters per second. Swim speed is capped at a lower limit of 1.90 m/s (Fully encumbered, holding a tool, no fins, underwater) and an upper limit of 7.60 m/s. Equipping tanks and the Reinforced Dive Suit will slow swimming speed. Advanced states of hunger and thirst also reduce swimming speed, at a rate proportional to the amount of severe hunger or thirst. Equipping any hand-held item (except the Seaglide) will reduce swim speed by 0.95 m/s.
