cat

Hi everyone, I'm currently working on the hydrodynamic design of an asymmetric hard-chine planing catamaran, and I'm hitting a wall regarding the early stage resistance prediction. The operating regime is 1<Fn <1.7. I initially reviewed the work by Ghassemzadehahrami et al. ("Development of a...

Hi Everyone. I might have been part of this website a long time ago. Designed a SST-120 tunnel hull a long time ago. I've been in the design world for a long time. Recently project managing large boat builds. Looking for a design to start with and then make. I can 3d model and cad/cut files...

Hey, Previously been looking for plans for aluminum cat, but after buying study plans realized that for a boat of 13-15m size will need 12000-16000 kg of aluminum, and just that would eat my entire budget for boat (current prices of Al sheets 8.5-11USD/kg). Then talked to a nav architect...

Hi Guys, I am new to forum and see their are some very helpful members with good knowledge on the Boat Design topic. I am busy studying boat design through Westlawn Institute of Marine Technology and I am on the lesson of multihull design. So I have started on a 1/10 scale model of a 22ft...

So I want to learn to how to determine how much in material I would need to build a 30-40 ft Cat hull out of the following materials. Lets say if I decide on a boat length of 38' and Beam of 18'. With 1/2" foam core. I will mention more attributes because I am digging for tools in case I want to...
