Hydrofoil Sprint
An original open-water 3D regatta with curved, procedurally modeled hydrofoil hulls, carbon struts and wings, articulated cockpit riders, animated water and island harbors. Automatic acceleration leaves you free to lean, choose high foil or grippy planing, and spend sprint charge. Follow the V-shaped wakes of actual simulated rivals to refill faster from course 7. Whitecaps arrive at course 17, and crosscurrents at course 33. All 48 seeded buoy courses have tested legal winning policies. Courses 1–3 require 75% clean gates, later courses require 85%; finish in the top three through course 16, then the top two in advanced regattas. Typical legal runs take about 26–53 seconds, with an 88-second timeout. Best score, unlocks and stars save between races. The UTC Daily uses a date-locked seed and awards a streak only for a win, once per date. This is forgiving arcade hydrodynamics, not a fluid simulator; islands are scenery rather than collision hazards.
How to play
- Tap Play, drag the lower helm left or right and follow the numbered diamond through each pair of buoy flags. Arrow keys or A/D also steer.
- Tap FOIL, or press F, to rise above the water and accelerate. Lower the foil before sharp turns or whitecaps for more grip. Hold BRAKE or Down to slow; hold SPRINT or Space to spend charge.
- Earn the displayed clean-gate target and required placing to unlock the next course. Pause with the on-screen button or Escape; Settle Hull recovers speed and balance without moving your boat. Retry starts the same seeded course.
Tips
- High foil is fast in a straight line but turns more slowly and drifts farther. Settle into planing before a demanding buoy carve.
- From course 7, ride a white V-shaped wake arm behind a rival, rather than its exact center line. The SURF indicator confirms faster sprint recharge.
- Whitecaps can stall an aggressively leaned high foil, but your hull rights itself and keeps racing. Advanced courses require a top-two finish; clean gates, efficient lift and wake time all improve the score.
Questions
Are friends together on the same water?
No. Each human independently races the identical seeded course with the same simulated boat rivals. The shared room compares finite skill-based scores and shows its final podium. Optional shared computer characters are separate scoreboard competitors.
Do the boats cheat or teleport?
No. Every on-water boat uses the same lift, acceleration, steering, whitecap, current, gate and wake rules. Their legal control policies differ: Pip prefers planing, while Marina and Sol learn higher-foil racing. Nearby craft gently separate; a stall slows and settles a hull without changing its position.
What happens when I leave the page?
Unlocked courses, stars and best score remain saved on this device. Changing tabs pauses an unfinished race and requires deliberate Resume. A stalled craft can settle itself or use Settle Hull from Pause. A WebGL failure provides a Reload button rather than claiming the game is ready.
