| Programs are released on the Software Forum at boatdesign.net. This is the best place to ask questions regarding the programs. | |
| SID Viscous: Wave resistance and free wave spectra of monohulls and ACV from longitudinal wave cuts. | |
| Michlet: Optimisation of monohulls and multihulls. | |
| Ulimich: A simple program to calculate Michell's Integral. No screen output makes it easy to call from VPP's. | |
| P2D: A simple 2D planing program. | |
| LSP: Thin-wing lifting surface program that estimates lift, induced drag, leading-edge and side-edge suction. | |
| MLWRI: Michell-Lamb Wave Resistance Integral for Wigley hulls. | |
| ZGREEN: Wave patterns made by isolated Havelock sources and sinks. | |
| In preparation... | |
| FIRM: Fully-Integrated Rowing Model. | |
| Flotilla 5.0: Resistance, squat and wave patterns of monohulls, catamarans, ACV and SES. | |
