ORC Superyacht On-line Application

   
 

Capturing the data to generate an ORCsy Certificate is not a trivial matter, but thanks to the ORC’s work and experience  the process can be executed quickly and accurately if the right documents, drawings and geometry files can be made available to the ORC handicapping team.

The first step is to submit a requirement to get an ORCsy Certificate. This is done by completing the Application Form below. This form captures a complete description of the vessel. Each input field has a brief explanation shown when cursors is placed over it.. All measurements shall be in meters to three decimal places except that sail measurements shall be to two places of decimals. Weights shall be in kilograms to one decimal place. Please use a point (56.453) as decimal separator.

Additionally, following documents shall be supplied to orcsy@orc.org by the superyacht technical representative, e.g. the Designer, Yard Representative or Project Manager.

  • Hull geometry file in OFF or 3d file format
  • Stability Booklet
  • Sail plan (preferably in DWG format)
  • Mast plan with measurements as per IMS Rule F4
  • Deck plan (preferably in DWG format)
  • Tanks plan (preferably in DWG format)
  • Propeller installation drawing (preferably in DWG format)
  • Other rating certificates

Using these information the ORC will complete the Measurement Form and return it for information and checking. If the above can be supplied the expectation is that an ORCsy certificate can be generated without a complete physical measurement of the yacht.

If any of the above are not available some physical measurement of the yacht may be required. This will need to be coordinated between the yacht representative and the ORC measurement team, and the yacht will need to be made available in a suitable condition (out of the water, free from scaffoldings and covers, etc.).

Thank you for taking time to digest this information, you are starting on a process that takes handicapping of superyachts into the mainstream of international sailing, and much of this will be unfamiliar territory to you. However the ORCsy team has several decades of experience in these processes, and has a track record of managing large fleets of International grand prix racing yachts.

Mainsail measurements

The mainsail is measured with width at the top (MHW, formerly HB) and four widths found on the leach between head and clew: at 1/4 (MQW, formerly MGL), 1/2 (MHW, formerly MGM), 3/4 (MTW, formerly MGU) and 7/8 (MUW, formerly MGT) leech heights. Points on the leech are found by folding the sail to find equal distances between clew and head or between two adjacent measurement points.

Mizzen measurements

The mizzen measurements are the same as for the mainsail measured with width at the top (MHWY, formerly HBY) and four widths found on the leach between head and clew: at 1/4 (MQWY, formerly MGLY), 1/2 (MHWY, formerly MGMY), 3/4 (MTWY, formerly MGUY) and 7/8 (MUWY, formerly MGTY) leech heights. Points on the leech are found by folding the sail to find equal distances between clew and head or between two adjacent measurement points.

Mizzen stasyail
Mizzen staysails shall be three-cornered. The longest side edge shall be taken as a luff, the shortest edge shall be taken as a foot, and third edge shall be taken as a leech. The following measurements shall be taken: YSD shall be the shortest distance that can be measured from head to foot. YSMG shall be the half width. YSF shall be the foot width.
Additionally, check appropriate box if a mizzen staysail is used reaching and/or downwind.
Symmetric spinnaker measurements
The symmetric spinnaker shall be symmetric in shape, material and cut, about a line joining the head to the center of the foot.

Symmetric spinnaker measurements include: leech and luff length (SLU = SLE, formerly SL), half width (SHW, formerly SMG) as the distance between midpoints on the luff and leech and the foot length (SFL, formerly SF).

Asymmetric spinnaker measurements

Any spinnaker not qualifying as symmetric shall be considered as asymmetric.

Asymmetric spinnaker measurements include: luff length (SLU), leech length (SLE), half width (SHW, formerly AMG) as the distance between midpoints on the luff and leech and the foot length (SFL, formerly ASF).

Headsail measurements

Headsail measurements are similar to those of the mainsail, including the top width (HHB, formerly JH) as well as four widths found on the leach between head and the clew: at 1/4 (HQW, formerly JGL), 1/2 (HHW, formerly JGM), 3/4 (HTW, formerly JGU) and 7/8 (HUW, formerly JGT) leech heights. Points on the leech are found by folding the sail to find equal distances between clew and head or between two adjacent measurement points. Additional measurements for headsails are: luff length (HLU, formerly JL) and luff perpendicular (HLP, formerly LPG) as the shortest distance from the clew point to the luff.

Additionally, select if the headsail is set with the furler or set flying and when it is furled more than 50% while tacking.
Unconvential sails

Unconventional sails are those sails that are not included among those already listed (mainsail, headsail, spinnaker, mizzen, mizzen stayasail). Measurements inlcude primary sail dimensions such as: Top length, Leech Length, Luff Length, Foot Length and Longest Perpendicular as well as sail area.

Additionally, check appropriate box if such a sail is used upwind, reaching or downwind.
P measurement

P is the distance between the black bands on the mast (or white bands on black masts) that are limiting the position of the mainsail luff - while racing the mainsail luff must be between these bands. In the absence of an upper or lower black band, P is measured to the upper part of the main halyard sheave from the point where the top of the boom intersects the mast.

PY measurement

PY is the distance between the black bands on the mizzen mast (or white bands on black masts) that are limiting the position of the mainsail luff - while racing the mizzen luff must be between these bands. In the absence of an upper or lower black band, P is measured to the upper part of the main halyard sheave from the point where the top of the boom intersects the mizzen mast.

E measurement

E is the measured distance from the aft side of the mast to the black band on the boom (or white band on black booms) that limits the position to which mainsail foot may be extended. In the absence of the black band, it shall be measured to the point on the boom as aft as the mainsail clew can reach.

EY measurement

EY is the measured distance from the aft side of the mizzen mast to the black band on the mizzen boom (or white band on black booms) that limits the position to which mizzen foot may be extended. In the absence of the black band, it shall be measured to the point on the boom as aft as the mizzen clew can reach.

BAS measurement

BAS is the height from the mast datum point (at the sheerline at the mast) to the boom or lower black band on the mast. It is used also as a reference point for the halyards hoist measurements on the mast.

BASY measurement

BASY is the height from the mizzen mast datum point (at the sheerline at the mast) to the boom or lower black band on the mizzen mast. It is used also as a reference point for the halyards hoist measurements on the mizzen mast.

J measurement

J is probably the best-known measurement on boat, since it is used to define the size of headsails. It is defined as the horizontal distance between the front side of the mast and the intersection of the forestay with the deck.

SPL measurement

Spinnaker pole length (SPL) is measured when the pole is forced outboard on its fitting to the mast in a horizontal position athwarthsips, from the boat's centerline to the extreme end of the pole.

You can leave it blank if you are not using a spinnaker pole.

TPS measurement

The tack point of spinnaker (TPS) when it is tacked on the boat's centerline is the distance from the foreside of the mast to the foremost point on which the asymmetric spinnaker can be tacked. If the bowsprit is retractable, TPS shall be measured with it in its fully-extended position.

You can leave it blank if you do not have a spinnaker tacked on the boat's centerline.

Mast profile measurements

Mast profile measurements include the maximum dimensions transversely (MDT1) and fore and aft (MDL1).

IG measurement

IG is defined as the height of the foretriangle and is the vertical distance from the mast datum point (at the sheerline at the mast) to the forestay attachment to the mast.

IY measurement

IY is the vertical distance from the mizzen mast datum point (at the sheerline at the mast) to the mizzen staysail attachment to the mast.

EB measurement

EB is the distance at deck level between the after side of the mainmast to the foreside of the mizzen mast.

ISP measurement

ISP is the spinnaker halyard height and is the maximum height that the head of the spinnaker can be hoisted measured from the mast datum point (at the sheerline at the mast).

Forestay tension

If the uppermost backstay is adjustable, this shall be recorded as "Aft"

If the forestay is adjustable and backstay is fixed, this shall be recorded as "Forward".
If the forestay is adjustable and backstay is adjustable, this shall be recorded as "Aft & Forward".

If neither the uppermost backstay nor the forestay itself is adjustable, this shall be recorded as "Fixed".

Use of sails while racing

Describe the use of sails while racing by entering:

Number of furled jibs when sailing upwind.
Number of headsails on board while racing (excluding storm jib).

Number or spinnakers on board when racing (including symmetric and asymmetric).

Check the box if inner headsails are unfurled while the biggest headsail is furled while tacking.
Inner forestay

If there is an inner stay, and if the tension may be adjusted, this be recorded as "Adjustable"

If the inner stay tension can not be adjsuted, this shall be recorder as "Fixed"
If there is no inner forestay, this shall be recorded as "None Fitted".
