The canopy failed? Isn't that unusual? Was it custom or factory built?

So that means anything, active or passive, added to deal with "outside the box" issues will affect the performance, the inevitable compromise that Ad Hoc wrote about. Then the question becomes, it that acceptable to this particular high-performance enthusiast community? So far, the answer...

Hi daiquiri. To my untrained eye, I do not see evidence in shape features of these boats that this aerodynamic stability consideration is included. Could you post some photograph examples where it is present? (Edit: beyond the ground-effect consideration)

I think you had mentioned this before in another thread, what was the full test weight of the trimaran? Also, what was the total surface area of the lifting foils please?

That is a SWATH configuration, i.e., the hulls are submerged, which will feature more drag for your electric motor than hulls that float on the surface. The resistance will be even higher if you add the third hull that you mentioned.

I'm no expert but I don't see how this is any different from say, the Trimaran designs that Kurt Hughes offers, for example. Is this really new?

for those of you attending IBEX 2013 this month, Vlad will be giving a seminar entitled: SpeedDream: Lessons from a Prototype

What's underneath all of the floor-boards with the finger-holes for lifting?

What is the proper name and design intent of this bow shape please? Is it a "piercer" with added reserve buoyancy for when the waves become larger? According to the Flickr description, it is a Samoan fishing canoe. To my untrained eye it is hydrodynamically sophisticated and beautiful. from...

Congratulations. I was wondering approximately how much total area required the use of angle-grinding and how many total man-hours were spent on part one alone?

This thread has derailed and unfortunately, the original thread in German hasn't been updated. I think that the moderator should lock this thread. Hopefully, someone else working on a project based on this concept will begin a new thread without the personal postings.

If a forum member starts a thread for the purpose of soliciting input and advice, and another forum member (such as Leo) reasonably believes that the thread OP is in over their heads and may cause harm to themselves or others, it is neither a kindness nor a responsible act to enable, encourage...

I must have missed it. What deadline and why? What is your complete time frame for the whole project. As an inexperienced but aspiring builder-wannabe, I'm nervous for you reading this. Isn't this your dream project, that you've wrestled with for years and now you're making a crucial...

Leo is correct.

How about a 44 meter Cat with super-sized steps?

Hello parkland I see that you've modified your original SOR to include folding pontoons, which reminded me of this patented, trailerable houseboat: (skip ahead to the 3:42 mark) KgOOHjbG9qM

As an inexperienced boat-builder myself, but experienced in other types of fabrication, that time-frame for just the hulls and basic structure could work with an experienced group of workers, but if it's just you with a steep learning curve and a little help, it's likely not realistic.

Doug and Ad Hoc... You two guys are entertaining. Oil and water mix better.

I don't think Dennis intended to do harm or guide people down the wrong path. I imagine that he got excited about being able to produce a hull shape with simple metal shaping equipment (a brake). After looking through his website, my strong suggestion would be to update it by clearly stating...
