how fast does a sailfish swim
Some estimate 60 mph (96 kph) or faster. It also has a strong backbone and a sturdy crescent-shaped tail to complete the sprinting swimmer's body. Close behind the sailfish in the top speed racers of fish are other open-water hunters. Those would be the swordfish, marlin, wahoo, yellowfin tuna and bluefin tuna.ne of the secrets of the sailfish's speed, along with that of these other fast predators, lies in its musculature. It has huge amounts of white muscle, great for acceleration but not stamina. This is then boosted along the flanks by blocks of red muscle which need more oxygen but are good for sustained fast swimming.
