I dont like to end up on the bottom of the sea so boat will be very strong! zeyang Wow! Very interesting process. 8MM aloy hull plate for this size boat is real superstrong. R u using 5K series aloy plate? You will need a very good welding machine and welder to do this job. Why don't u build the frame in aluminium to save you time and money? I though you will going to build the boat in lumber? |

 如果有机会在暑假或者寒假期间路过广西的海岸线，倒是可以考虑一起航海一段时间哦~！呵呵：） |

The wood frames are only templates they will be replaced with t-bar aluminium forms each 60 cm. Im using 5081 8mm for the hull. im welding using a 250 Ah Lincoln TIG-welding machine and a Lincon 450 Ah Mig machine. if you are curious you can see the link here. http://weldingweb.com/showthread.php?t=29094&page=7 zeyang |

frames :-) The reason for not weld the frame to the hull is to avoid "starve-horse" look. Sometimes you can see the frames through the hull due to welding distortion.  |

Aluminium is much stronger than fiberglass and not so heavy as metal, so its almost a dream choice for a sailboat. Only drawback is price. Aluminum is not exactly cheap material. The price of today is around 30 rmb/kg. |

I think Zeyang you probally did lot of research before decided use aluminum. From my own opinion. Steel would be a better choice than aluminium. Since weight is not an issue for cruising sailboat. You must pay more attention to your electrical system when you build a metal boat. Especially an aluminium boat. Galvanic corrosion can make a hole in the hull very quick. Must use isolation transformer when plug in A/C shore power. |

Must use isolation transformer when plug in A/C shore power. I agree. steel could be an option. there is two reason why i didnt choose. 1. its heavy to work with. Im mostly alone so I need means to carry it and need more heavy cutting tools than i use (i use ordinary woodworking tools) 2. steel rust. it you dont spend time protect scratches your boat will look like an old russian oil-tanker. i dont even need to paint it. when it comes to corrosion. this will be taken care of. i will try to keep electricity to a minimum anyway. a battery and 2 wires up to the navigation lights :-) Ok, not so simple but not far away either. there is plenty of boats using aluminium these days anyway. cost is the biggest drawback. building it in steel will probably be 1/3 of the cost. zeyang one life, live it. |

I have been thinking and dreaming about boatbuilding 24 hours a day last 3 years. :-) When you start dreaming about sailing to the end of the world, there is no cure for such addiction hehe zeyang, one life, live it |

Steel ballast is low-cost and supply strength, and it is environmental and nontoxic for oceans. In structure, you can cut some steel board as keel shape and set them into original aluminum keel. Certainly it has electrolytic corrosion, but Lead too. Use resin insulate the steel and aluminum. |

Certainly it has electrolytic corrosion, but Lead too. Use resin insulate the steel and aluminum. Problem with steel is, i cant form it myself in different shapes. I will make lead ingots in square shape stacked on top of eachother. (weight around 20 kg each) Reason for using small ingots is. If for some reason i get stranded somehwere, i can easily take them out to make the boat less heavy in emergency. The lead will never be in contact with ocean so environmental it will no problem. (its inside the keelbox) Originally this boat has steel-ballast formed as the keel on outside. Fastened with bolts to the wood hull. Zeyang |
