| Inputs | Value | Unit | Notes | |
| T | 6000 | lbs | ||
| Tf | 80% | Thrust factor from Specification (Section 079) | ||
| F | 4800 | lbs | = T * F | |
| theta | deg | Angle of Towline from H-Bitt to Deck Chock | ||
| H | ft | Distance from LCB to top of H-Bitt | ||
| V | ft | Transverse Distance from CL to H-Bitt | ||
| Hd | ft | Height of Towline from LCB after Deck Chock | ||
| Vd | ft | Transverse Distance from CL to Deck Chock |

| F' | 4,800 | lbs | = F / COS (ϴ) |
| F'h | 4,800 | lbs | = F * COS (ϴ) |
| F'v | 0 | lbs | = F * SIN (ϴ) |
| Mv | 0 | ft-lbs | = (F'v * V) - (F'v *Vd) |
| Mh | 0 | ft-lbs | = (F'h * H) + (F'h * Vd) - (F'h * Vd) |
HMMT 0 ft-lbs = Mv + Mh image1.png
