"Scott Russell had often pointed out the necessity of going to lengths approaching 400 feet for speeds of about 20 knots, and it had become axiomatic that high speeds could only be attained in vessels of great length. As a result, there was considerable scepticism about newspaper reports that seam launches of about 50 feet - "built by Mr Thornycroft of Chiswick" - had reached speeds varying from 17 to 19 statute miles per hour." The explanation for the high speeds achieved was that Thornycroft had succeeded in building a very light hull with very light machinery.
