Hi all, I have many questions I'll surely follow up with, but to start, I'm looking to build a floating home for my wife and I to settle on to avoid exorbitant rent in NYC. We'll be tweaking a lot of things with the design as we get closer to realizing it (need to save up some money and will...

Good day all. I'll keep this short and sweet. Looking for your aluminum yacht building expertise: I am considering the idea of casting a lead bulb, hydrodynamically fair and bolt it to an aluminum fin shaped keel. Seeking advise regarding if this concept of attaching a lead bulb to an aluminum...

Hello from Lancashire, England. I've been building my mini boat, which is 7'3" at the waterline, since January. The aluminium hull was the easy part but getting it to go and steer were a nightmare. I'm a keen cyclist so thought that it should be pedal powered. A trolling motor would be too easy...

I am researching these two building methods from the standpoint of durability, longevity, cost of ownership over time and eventual resale value. I am quite aware of corrosion issues associated with aluminum and I am also aware that with proper attention aluminum corrosion can be prevented. With...

This boat is hull number 3 - the previous two hulls were 1:10 scale models laser cut TIG welded aluminum: 2020_Tenth The first two were built in a highrise building on the 17th floor and I was limited by space and what size I could fit into the elevator. The basic hull specs for this...

Hello ! I appreciate being able to join this network. For the last couple of months an idea has been formulating in my mind about designing and building a rugged, trailer-able aluminum sailboat in the 7-8m (23-26ft) range. Based on what I have read on here and elsewhere, the general consensus...

Hi, this is my first post to this forum. I'm designing a bow thruster tunnel for an aluminum-hull houseboat. I have tried to find references in the ABS rules for aluminum hull penetrations, but the only things I've found so far are for steel. I am specifically looking for rules regarding...
