GregW 28 Posted April 10, 2016 Share Posted April 10, 2016 Joining the reverse bow (Cat) club. 3 in build in the Philippines evidently including a carbon racing version with C foils. Be interesting to see how that goes...... http://www.f-boat.com/pages/News5/F-45Release.html Quote Link to post Share on other sites
Black Panther 1,568 Posted April 10, 2016 Share Posted April 10, 2016 I still can't see the advantage of the bow going backwards. OK if you are designing to a rule where LWL is fixed, but why on an ordinary boat??? Quote Link to post Share on other sites
Ed 143 Posted April 10, 2016 Share Posted April 10, 2016 Takes weight out of the bows and reduces pitching moment if done right. With it being designed by farrier it probably has been Quote Link to post Share on other sites
erice 732 Posted April 10, 2016 Share Posted April 10, 2016 more buoyancy fwd volume above the waterline is just weight + reserve buoyancy Quote Link to post Share on other sites
Black Panther 1,568 Posted April 10, 2016 Share Posted April 10, 2016 I get those arguments, but only if you are restricted by one measurement. If you were designing boat that had to fit in a 12m berth or a measurement rule. But if you are designing a boat without restrictions then why not just make it 1m longer with a real bow that will be drier, have more reserve buoyancy, an easier deck to walk around on and probably a little more volume below?

madyottie 82 Posted April 10, 2016 Share Posted April 10, 2016 I can see an advantage for a tri like TW in that when the main hull lifts, the deck of the ama is very close to the water. pinching the top would provide less chance of doing the big endo if you stuck it under, as there's no big flat surface to resist the water. For a racing cat I guess it's less weight and windage, as mentioned above. For a cruising cat (or tri) I'm with BP. What's the point? It just makes a 45 foot boat a bit smaller. Kinda like the tumblehome on those old IOR boats. Quote Link to post Share on other sites
Clipper 343 Posted April 10, 2016 Share Posted April 10, 2016 In a performance boat you don't necessarily want more reserve buoyancy. If the bow goes in, you don't a big brake of a deck or massive bow to stop you. Cutting 'through' waves rather than bouncing over is another way of looking at it.
