The 2018 edition of the ORC's Superyacht Designer
VPP (DVP) and Superyacht Sailor Services (ORCsy SaS) is now online
and available for use. The DVP is available for purchase and
download on the ORC website. The ORC Superyacht VPP (ORCsy VPP) is a
Velocity Prediction Program that forms the core of the ORC
SuperYacht Rule (ORCsy).
The software is accompanied by the ORC Manager, an editor utility
program for entering and editing measurement data as well as an
Offset editor for editing hull offset files. Input data in DXT and
OFF file formats can then be used to produce the hydrostatic data
and polar diagrams that predict boat speed for full range of wind
conditions above 6 knots of true wind speed at the following true
wind angles: optimum beat, 52, 60, 75, 90, 110, 120, 135, 150
degrees and optimum run.
The ORCsy VPP Designer's version (DVP) uses the same software used
by the ORC Central Rating Office to issue certificates.
The results data includes all the ratings and time allowances shown
on certificate, together with a complete set of calculated hydro and
aerodynamic data and that defined by the ORCsy rules. The ORCsy DVP
is Windows-based software, easy to use, with a user-friendly
interface and standard Windows functions.
Any designer may process design data through the VPP to analyze
rating effects, and the software is therefore regarded as essential
to anyone contemplating an ORCsy design project. The subscription
will not give access to existing hull data without the written
permission of its designer, while rig, sails and other measurements
can be obtained from any copy of an ORCsy Certificate through ORCsy
Sailor Services. The annual subscription to the ORCsy DVP is
€1200 while the price for
current ORC DVP subscribers is €840.
Upon receipt of your payment, new subscribers will receive
credentials to log on to the DVP Subscribers web page, while
credentials of existing subscribers will be renewed. From this DVP
page you can download the installation software package and
regularly check for updates for one year of both the VPP core and
the editing and management interfaces.
The ORCSY rule is only 3 years old now but highly successful, having
been used in 9 events in the 2017 season: SuperYacht Challenge
Antigua, Swan Cup in Virgin Gorda, Loro Piana SuperYacht Regatta in
Virgin Gorda, St. Barth's Bucket Regatta, Loro Piana SuperYacht
Regatta in Porto Cervo, America’s Cup Regatta in Bermuda, Superyacht
Cup in Palma, Candy Store Cup in Newport, Maxi Yacht Rolex Cup and
Rolex
The ORCsy team has worked hard to improve the level of accuracy of
the ORCsy VPP, and during this past year supported a continuous
program of research as well as the presence of its technical Super
Yacht team at all events. Along with the SuperYacht Racing
Association (SYRA), ORC will continue its support this year to
develop and update this unique rating system.The principal new
characteristics of the 2018 ORCsy VPP are the following:
-
PIPA - New formulation for 3 and 4
blades feathering propellers. The coding of the new
treatment of the 3 and 4 blades feathering propellers with the
help of a CFD made by Briand office (checked using Hoerner
formulation) has been completed
-
Dynamic Alowance - The amount
of max Dynamic Allowance was reduced at 8% (from 10%) revising
also its composition, giving more power at SA/DSPL and LVR terms
reducing the effect for the high displacement boats
-
Tacking Allowance - Max Tacking
Allowance was increased to 3% from 2%, keeping the same
formulation
-
Lifting Centerboards - The slot
resistance has been removed for vertical centerboard as there is
no slot in these fins
-
Mizzen staysails - The rated
area of mizzen staysail has been reduced to the 70% of measured
area
-
Haedsail number allowance -The
allowance has been increased by 0.5% for the presence of a
furler
-
Power function - This function
that measures the efficiency of the spinnaker according to
bowsprit length, has been increase of about 8% following ORC INT
modification
-
ORC International 2018 modifications
have been included: windage drag (hull+crew) increased, hydro
induced drag increased (with different keel and rudder load
sharing), crew weight transversal shift
-
Stanchions - No light stanchion
gyradius correction (useless in SY)
-
Runners - No windage for
runners
-
Headsail set flying - Detuning
of lift coefficients at low wind angles (20-25 degrees)
-
Gaff windage - Slightly reduced
-
Lenticular rig - Slightly
increased windage
-
Declared certificates penalty -
A penalty of 1% on all allowances has been introduced for
DECLARED certificates, replacing the previous increase of 5% for
Righting Moment
The above modifications have been introduced to
assess in a more scientific way the characteristics of the big Super
Yachts. SuperYacht Sailor Service and Designer DVP on the ORCsy web
page are updated with the vew VPP version. All certificates already
issued as preliminary will be updated in accordance with the new VPP
release.
