Previous theories and empirical formulas for the lift of flat planing surfaces are reviewed, and the resemblance of the planing surface to the airfoil noted. A simple expression, which converges to the correct limits for exactly known cases, is assumed for the ratio of planing to airfoil lift, and the planing lift is then estimated by using airfoil experimental data. The resulting calculated va...

A numerical re-formulation of Marou’s integral for slender body analysis of calm-water planing hydrodynamics with gravity wave-making is developed. Numerical computations are performed first for a flat triangular planing plate. The triangular planing plate has been the subject of previous work with the base Maruo theory. The comparisons are supportive of the formulation for performing wave lift...

A comprehensive and critical review of literature pertaining to the study of planing craft is given within this work. This study includes monohull design, analysis and performance prediction for flat water; many features of the planing characteristics, including dynamic stability, the use of stepped hullforms, re-entrant transoms and flow characteristics are detailed. Work on the rough water se...

Hydrodynamics of porpoising instability in vertical-plane motions of high-speed planing vessels have been investigated for years. However, not much work has been published on dynamic control of vertical-plane motions of planing boats by controllable appendages. In this paper, effects of controllable transom flaps on heave/pitch motion characteristics of high-speed planing vessels are investigat...

OBJECTIVES Locally used doxycycline has been shown to concentrate in crevicular fluid and demonstrates a wide spectrum of activity against the periodontal pathogens. The aim of the present clinical study was to evaluate the efficacy of doxycyline hyclate 10% as an adjunct to scaling and root planing in the treatment of chronic periodontitis. MATERIAL AND METHODS 60 systemically healthy, chron...
