Wakesurf Ballast Calculator
Pick your boat, set your weight and wave preference, and get a starting ballast, speed, and rope setup. The per-boat helper the rest of the industry doesn't have.
Your setup
Suggested starting point
- Surf-side ballast
- 1,500–1,900 lbs
- Off-side ballast
- Light / empty, then trim to clean the wash
- Boat speed
- 11.0–11.3 mph
- Rope length
- 18–22 ft
Generic estimate — pick a boat for a capacity-aware suggestion. Bias weight to the surf side, then fine-tune speed in ±0.2 mph steps until the wave cleans up. This is a starting point, not a rule.
