A set of tree 2m models (M8,9,10) are wave-analyzed, where importance is placed in the bow wave analysis rather than in the resultant wave analysis. The three models are generated from the central vertical plane distribution of sources, whose draftwise distribution is varied as V, U and Λ types under the given restriction of [numerical formula]. The measured wave patterns show the "averaged" parallel shift (Δx, Δy) as well as the "local" distortion in co-ordination to the calculated wave patterns, where Δy is roughly estimated as B/2. The "measured" bow wave amplitude A_f (θ) is found always smaller than the "calculated" amplitude throughout the whole range of [numerical formula]. Particularly, reduction is by far more remarkable around [numerical formula]. The "measured" bow wave amplitude A_f (θ) as well as in "measured" wave profiles and/or in "measured" C_W for the tested three models V, U andΛ is not consistent with that of the linearized theory. This may suggest a kind of empirical correction factor α_2 (ζ) to be applied just for the "wave-making" (not for the "hull-generating") strength of source, such as [numerical formula] (where ζ-f/T (f = immersion of source, T = draft of distributionplane).
