Need help to understand zi and zi-1 of RINA rules C3.2.6.3.3. Please give an example. Thanks. [IMG]
what could be the best software to use to model this non-symmetrical local hull and the software to predict the speed and resistance?
Is Flotilla free? I have offsets already for this catamaran but my problem is the hull is not symmetrical. How do I input this to Michlet? In...
I'm planning to use FreeShip and Michlet to make this catamaran but I'm not sure if it can be modelled in FreeShip and Michlet can give a reliable...
What could be the OPC using outboard engines? Do you need more info?
Thanks I need to get a copy of the SSC rules...Unfortunately there's no free pdf download.
I'm using three (3) outboard engines.
Anyone have made an operational envelope calculation using RINA Rules? I did an acg calcs but I can't find the formula to incorporate wave...
my problem is not getting the equipment number but the weight of the anchor to use because the equipment number i get is 15 which you cannot see...
Using the Maxsurf Hull Speed, what is the value of Overall Efficiency do you use for 15m Patrol Boat?
Yes. I use DNV Rules for Patrol Boats. I have also the calculation written in excel. You need to correct the formula (C2^2/3) to C2^(2/3).
Thanks. I'll take heed on the answers next time.
Just want to know which acg should I use when making an operating envelope. Everytime I change the waveheight the acgw and acg below changes....
for 14.5m patrol boat. I doubled check. Using DNV I got 15.4 while 15.1 in BV. DNV has anchor selection for EN 30 up whiel BV has EN 19 up.
I can't see in the rules where to use Acg for calculating frp structures:...
im using dnv hsc rules for calculating the 15m patrol boats structure but I cannot find the formula for calculating the section modulus...
how can i choose an anchor if the equipment number is less than the value listed by class in the table? i'm getting 10-15 en.
using dnv formula I got this: [IMG] What do you get in Savitsky using the same value I used?
Thanks. It is clear now.
If I use the formula in Pt.3 Ch.1 Sec.2 B204, what should be the value of Vs and Hs to get the max design vertical acceleration? Is the Vs the...
