The enquirers had seen Tystie and liked the accommodation layout, but needed it stretched lengthways, and upwards, to make it a more relaxed fit for six-footers. When I described the size of project that building a 38ft boat is, in manpower terms, it became clear to them that they'd better just dream about building. It really does take a full-time team of at least two, preferably three, people to build something this big within a reasonable timescale.
Yes, I'd keep Tystie's general layout, but there would be no need for the settees to overlap with the central double bed. Also, I'd reduce the size of the nav desk to folded-chart size, as electronic navigation is now prevalent, allocating more room to the heads.
