Query: Capillary-gravity waves: a "fixed-depth" analysis   We study the onset of the wave-resistance due to the generation of
capillary-gravity waves by a partially immersed moving object in the case where
the object is hold at a fixed immersion depth. We show that, in this case, the
wave resistance varies continuously with the velocity, in qualitative
accordance with recent experiments by Burghelea et al. (Phys. Rev. Lett. 86,
2557 (2001)).
