Hi, ABS rules are quite old and not very "advanced". I think that with DNV you would be able to save some weight because they can keep into...
The breaking strength of the stopper makes more sense to me than the halyard. A normal Spinlock for a 10m boat has a breaking load of around...
Thank you for your replies. However, I think that using the tack line breaking strength would lead to an oversized sprit. A 10 mm rope nowadays...
Hello, I need to design a carbon bowsprit for a gennaker. I didn't find on any book any formula for calculating the tack load. The only thing...
No, there isn't a RULE. They are just more efficient if placed normal to the shell plate. If they are placed at a different angle, the bending...
Ok, this looks like a quiz! so it's not a yacht, why did you ask for a yacht code then?! If this is the case, you should comply with SOLAS and...
How long is the boat? Assuming it is more than 24m... there are no statutory stability requirements for a private vessel!! However, LR SSC has its...
Is it a research vessel or a yacht? If it is a research vessel I'm afraid it will have to comply with SOLAS (although there will be many not...
I was talking about a 20million construction budget, the final price is another thing.. anyway, since there is a gap between € and $, I think we...
I think there are two different approaches from the owner's side, that can make the difference: A- The owner buys a full project from a design...
Hello, when I have to do composite structual calculations, usually I start from given mechanical properties of the laminas in order to obtain the...
I'm not sure that my rudder is exactly as shown in the picture. However, the skeglet wraps around the leading edge so maybe it just looks like the...
The design number of the boat is #65, same as Rangiriri mentioned above. I made some calculations on the original and actual theoretical centres...
Modifying the rudder sounds a good idea, although I have a large bustle fwd of the rudder, so I cannot balance the rudder without removing the...
Thank you for your replies! First of all, the rudder angle in close haul at 10 knots is about 5 degrees. The crew onboard can vary from 4 to 7...
Hello, I have a Farr 31 half tonner, and it suffers heavy weather helm, of course increasing with the wind speed. The rig is fractional 7/8 (even...
Hello, I'm looking for mechanical properties of titanium (elastic modulus, strenght, ecc.) Thanks Stefano
I think it's not so difficult to get enough carbon for a boom here... Please can we go back to the original thread, otherwise we can start...
www.strand7.com it has a very good price/quality ratio, many naval architects use it. However, my opinion is that the costs of CFD and FEA...
