MICHLET
	Michlet calculates the total resistance, far-field wave elevations and sea-bed pressures of thin monohulls and multihulls. Artificial life methods are used to minimise resistance and wave elevations. The program runs under Windows on most modern PCs. Examples bundled with the program include kayaks, rowing shells, catamarans, proas, SWATH, trimarans, tetramarans, pentamarans, submarines, frigates and destroyers.
	Free Versions
	Version 8.07 is available for free from boatdesign.net.
	The boatdesign.net Software Forum is an excellent place to discuss Michlet's capabilities and deficiencies, and those of other ship-related programs.
	A manual and tutorial are now available in Spanish. Many thanks to Rámon Hernández-Ortega who translated the manual, wrote the tutorial, and made them freely available. Although these papers relate to version 8.05, the changes in versions 8.06 and 8.07 are very minor. Download (pdf): Manual in Spanish Tutorial in Spanish.

	MANUALS
	Manuals have been LaTeXed and converted to pdf format by Misha Lazauskas. Michlet manual Michlet examples and templates Godzilla manual Godzilla examples and templates.
	LONGITUDINAL METACENTRIC HEIGHT
	Constraints can now be placed on the longitudinal metacentric height as well as GMT. Older Godzilla input files (versions 8.x and 9.0x) will need to be modified by including the minimum and the maximum GML allowed during the optimisation procedure.
	INPUT FILES
	Input files for earlier versions (e.g. version 8.0x and those produced by FreeShip and DELFTship) require the inclusion of a couple of additional lines to work with Michlet 9.0 and later. If your old Michlet input files do not work with Version 9.x, check that you have included the lines specifying the Viscous Form Factor Method after the lines for the Skin Friction Method.
	SPLINE OUTPUT
	On exit from Michlet, hull offsets are now saved in Michlet's cubic spline format, as well as a table of offsets, and also a format that can be read by Delftship and Freeship.
	HULL SERIES 32
	GODZILLA examples have been included to illustrate the use of the 32-parameter hull series.
	SEA-BED PRESSURES
	Michlet now handles sea-bed pressures for multiple vessels. The example of 5 identical but randomly-located frigates (see the frig5sig.mlt input file) should produce a plot like this:
