Interesting. My first thoughts are... the boat will need to be kept extremely light to achieve these figures, which will sacrifice ride quality. However, a wave-piercing, narrow hull form would help compensate for this. While the cruise speed sounds reasonable, the top speed sounds a little optimistic. The first hurdle is getting a 74' boat to plane with 1250 hp connected to a single waterjet. Marginal, but not impossible, IF... the boat was simply a shell, with engines, tanks and running gear, coupled with a shallow deadrise hull... the figures are sustainable. As a fitted-out yacht, with all the trimmings... I think weight will be a critical factor. It's seems piercing mono hulls are the latest industry darling, but we have to keep in mind... they're not for everyone. Just people with an endless supply of windshield wiper blades. Still... I love the design. Thank you for bringing this to YF Innomare!
