You can apply H.2.1.12 with EINAl = EINAb. You calculate the two tables H2 with the two bending moments Mdb and Mdl. H3 is for stiffeners only.
I gave the link for the three suppliers, you will find all specs/inertia on their websites. Where do you get that 25% figure? The Wilderness...
Absolutely not. As you state yourself, "cost is only relevant when the idea has proven itself enough to go to the next level of production and...
Groper, could you please give me examples of blogs for the construction of yachts in Europe in flat panel with self-made lamination? I am looking...
We drift away from the topic of this thread, but briefly: Would you build e.g. a Wilderness 1230 in Europe, then 1. SD won't give the CAD...
95/25/CE certification is for the private leisure industry, not for commercial. There are some countries in the EU (e.g. France) that allow...
Sorry my mistake. Indeed l/b < 2 => apply H.2.1.12 (analysis in the two dimensions)
The equivalent panel would normally be 2300 x 404 mm. But length need not be more than 330 LH, so panel can be taken as 1980 x 404 mm.
Hi Rob, Sent. You might not be aware as you don't have follow CE regulations, but building with panels having guaranteed structural properties...
Question 1: take l = 1980 mm. Question 2: take b = 0.93 m2 / 2.3 m = 404 mm Question 3: Annex H is for the uncommon case where the material is...
Vinylester, though being a modified polyester, is still an ester resin; and it will generally absorb around 4% water in weight. I would use balsa...
Actually you can't do without the top cross member with stayed rigs. The masts are stayed on one side only, so the cross member brings the stress...
Hi Rob, when I quote 9 kAUD for the rig and 20 kAUD including cars, mast tracks, all sails and running sheets, believe me, you can have those...
As mentioned, this is as per ISO 15084, the standard uses UTS. This UTS value is the one of the chain/rope, not the SS bolt. Let's say it is an...
Hi Rob, So the 17k price was for one mast only?! Apparently I was not the only one mistaken, as Whimsical wrote on his blog: "Cost:- Rob denny...
I don't know about ABS, but in CEN ISO 15084 the anchoring point has to resist a minimum of 125% of the ultimate tensile strength of the rope or...
95% of Lagoon cats are sold to charter companies -mainly due to the way fiscal incentives work in France and Italy for long term rentals....
By the way, between Rob Denney original estimate of 17 kAUD, and final cost of 60 kAUD (estimating sails and fittings to 10 kAUD), it is a huge...
Hi Ozone, good to have you here, I think we are many here following biplane rigs development on the three Wilderness to come. That would raise...
I doubt the bow down trim is due to remaining building gear. The only changes from the standard Wilderness are forward masts (650kg) and bulkhead...
