Yes, female mold gives a nice finish for the boat, but if this is just 1 boat, I have to think is it worth it. I have done a lot of smaller size molds, but never this big. I have seen that people use steel tubes to give more strength, but I was thinking would a core do the same thing. Example...

Hi! I am thinking to CNC mill a Polyurethane plug of powerboat. I am still thinking that should I make a female mould, or just one off boat, and use the plug as a "male mould". Maybe if I get someone else to interested to join the project I will make the mould, as just for 1 boat, its too much...

Hi! I can CNC mill Polyurethane plugs for mould making use. It is possible to CNC other soft materials also, like mdf, but we can't mill metal. Our company is located in Finland. PM or email: info@finnluxury.com

Any suggest what kind of test I could do with it? Maybe best would be attach other side to something, and add something like 200kg in other end, and measure how much it bend.. Also I could try to hit something sharp, to broke the surface.. I have put 2 bricks to sides and sheet over it, and...

I have infused the 25mm easycell now.. 2 layers of 600gr biaxial fiberglass for both sides.. Very rigid!

Gurit says this in their website? "Gurit® Corecell™ S can also replace other materials, such as plywood, when creating high strength inserts for through-bolting in composite laminates." So what do U think? Could this be used in the places where I would need just normal solid fiberglass because...

They do this just like I have thinking it should be done. https://www.youtube.com/watch?v=T3dCB-pB_aA

Hi! Thanks for the reply. This hull design is not made by me.. I am only thinking to produce it. It is made with Rhino program. I have a good designer who have a lot of experience of using rhino 4. He can easily modified this model. I have talked to two catamaran builders, who build 10 meter...

Lot of question marks.. heh.. I understand it as I didn't really add much of an information as I were more likely asking what U think about the length / width ratio etc. But anyway. It will be Sailboat, with 2 diesel engines. My plan was to make it big enough, that I can live inside of it while...

What U think about these dimensions at the photos? It is quite big. If I end up to build this, I were thinking to use 25mm M-Corecell, and Triaxial fiberglass skins over it, 4mm outer and 3mm inner skin, and good internal structure.

I bought EasyCell75 Closed Cell PVC Foam 25mm thick. I will test it with 2 layers of Biaxial Glass Cloth 600g to both sides. Does anyone has any experience with EasyCell? I will do vacuum infusion with epoxy. I will make 550mm x 545mm size panel. I can post photos if anyone is interested about...
