The following are estimated specification options and are subject to change without notice.
| GULL 24 | GULL 44 | GULL 68 | |
| Power (SHP) | 4 | 19 | 45 |
|---|---|---|---|
| Wing span (metres) | 2.7 | 5 | 7.6 |
| Max Weight (adverse sea conditions) (KG) | 18 | 93 | 250 |
| Useful load (adverse sea conditions) (KG) | 6 | 34 | 94 |
| Max range, 66% useful-load as fuel (nm) | 507 | 985 | 1124 |
| Max level flight speed (knots) | 74 | 92 | 100 |
| Regular wave height capacity, unbroken | Any | Any | Any |
| Irregular wave or surf height capacity (metres) | 0.3 | 0.55 | 0.72 |
These wave capability claims, which are compatible with fresh Seastate 3 for the smallest GULL, are achieved by accelerating only when there is a clear distance to take-off. The GULL is aided by its high lift capacity, high thrust-weight ratio and exceptional features maintaining control authority in the severe turbulence encountered over such rough water.
