I have a velcro loop around the boom at the clew of the mainsail (25.6 m² full-batten square-top sail) of my Classe Mini 6.50. Works like a charm...
Murky Deep, to be honest I would then consider a new design from scratch if you intend to build a sailboat. Sure, just about anything will sail...
Okay, given the bulkhead heights larger than the hull depth at each station I did a small assumption and added a deck which seems to look typical...
Not too sure about the latest versions of FreeShip, but in the professional DelftShip version you can define tanks and have their volumes...
The UK Cherub guys have set up some nice instructions on how to make a carbon mast: *click* The general process would be the same for any other...
If you do not already know: "Destriero", Professional BoatBuilder Magazine, Issue 109, Oct/Nov 2007 "Record Run", Professional BoatBuilder...
She's laid up at the Lürssen shipyard in Lemwerder, Germany, for some years now (I think since 2009), in quite pitiful condition: [IMG]...
Mike, welcome to the forums. I suppose you already know this article on the Western Flyer (assuming it's the vessel in question)? There's a GA...
marufuddin0, you might want to check out PropCAD by HydroComp.
jake wilson, please see attached PDF for some design guidelines for bulbous bows. For sure not the ultimate stuff on that topic but it might get...
Why not? As long as you fulfil the applicable requirements for strength, stability and so on... Whether or not it's reasonable to do so is an...
stevee, you might try Carlson Hull Designer, a very simple software package that I admittedly have never liked due to its limitations, but it...
Yes, it's possible and has been done in the past on a few occasions. In principle the process is very similar to lengthening a ship, i.e. the...
pironiero, have a look at some of the latest production designs in the Classe Mini 6.50 (i.e. Vector, Maxi, to some extent also Wevo*). Due to...
Jürgen, thanks for sharing, this is a nice building method! Here in Lübeck, Germany, there is the Baltec Shipyard where they build catamarans...
Well, we're talking very basic stuff like displacement and centre of buoyancy here, using Simpson's rule - nothing fancy like damage stability or...
In general, this is not wrong at all. Most new designs are derived from previous designs and are only an affine transformation of a (hopefully...
If you google for "angle bar section modulus" or "t section modulus" you'll find dozens of tables and online calculators for this.
For simple rectangular cross sections, e.g. flat bars or shell plating: section modulus = (width * height)²/6 For more sophisticated cross...
Ghost Boy, welcome to the forum. I assume you know the longitudinal bending moments due to hogging and sagging of the vessel. From there you can...
