ORC Club On-line Application

   
 

It’s easy to get an ORC Club certificate for your boat. Just fill-out this on-line form, and the data will be processed and sent to the relevant ORC rating office who will then contact you when your certificate is ready. If there is no ORC Rating office in your country the certificate will be made by the ORC staff in the Central Rating Office who will contact you by e-mail.

If your boat complies with One Design Class rules, you can get an ORC One Design certificate with no additional measurement required by completing this form.

Please enter a valid e-mail address and as much data as possible. If you do not know the meaning of any measurements, place the cursor over the appropriate input field to get a short explanation. Further descriptions can be found in the measurement section of this website. If you still do not know where to find the data requested, leave the field blank and the Rating Office will assist in finding appropriate data for your boat.

Note that it is in your interest to provide the most accurate data possible – measured data is preferable to data that is declared or assumed by the designer, builder or other source. If the data provided is unusual compared to that from other comparable designs, the Rating Office may check the data, or decide this is incorrect and supply a more reasonable figure. When a data field is left blank, a default figure will be used what will give less favorable rating in comparison with fully measured values. And if there are unusual features to the boat or other comments you wish to make, please enter them in the “Other comments” field box.

Once a valid certificate is issued by a rating authority, ORC Club certificates will be entered automatically into the ORC Sailor Services database, where copies can be obtained and test certificates can be run for proposed changes in measurement trim. However, if these changes to the boat, its spars, sails or crew are permanent, you must contact your rating office to have new certificate issued.

Mainsail measurements

The mainsail is measured with width at the top (MHB) and four widths found on the leach between head and clew: at 1/4 (MQW), 1/2 (MHW), 3/4 (MTW) and 7/8 (MUW) 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.

Mainsail measurements can be provided by your sailmaker.

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 length (SLU = SLE), half width (SHW) as the distance between midpoints on the luff and leech and the foot length (SFL).

Symmetric spinnaker measurements can be provided by your sailmaker.

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) as the distance between midpoints on the luff and leech and the foot length (SGL).

Asymmetric spinnaker measurements can be provided by your sailmaker.

Headsail measurements

Headsail measurements are similar to those of the mainsail, including the top width (HHB) as well as four widths found on the leach between head and the clew: at 1/4 (HQW), 1/2 (HHW), 3/4 (HTW) and 7/8 (HUW) 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) and luff perpendicular (HLP) as the shortest distance from the clew point to the luff.

If there is no any roach it is enough to enter HLP and HLU only.

Headsail measurements can be provided by your sailmaker.

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.

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.

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.

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.

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".

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".
Forward Accommodation

Select "Yes" if there is interior volume forward of the mast which is fully fitted out as a separate sleeping or living space and built of solid construction, including bunks, personal gear stowage, etc.

Accommodation Regulations

Select the category according to the IMS Accommodation Regulations.

Non-manual power

If non-manual power can be used for adjusting rigging or spars, this shall be selected as follows:

"Sheets" when non-manual power is used for adjusting the clew of a sail or a boom.
"Rig" when non-manual power is used for adjusting the backstay, vang or outhaul.

"Rig & Sheet" includes "Rig" and "Sheets" together.

"No" when there is no non-manual power used.
Hull Construction

Hull construction shall be recorded as one of the following:

"Solid": Non-cored, solid E-glass, metal or wood hull and deck, but including also E-glass decks with core material.
"Cored": Hull skin of E-glass or wood, but incorporating a core material of less density that the skin

"Light": All other construction types, but excluding the incorporation of any carbon fiber.

"Carbon:" Where carbon fiber has been incorporated anywhere in the construction of the hull and/or deck, except as only reinforcement in the hull structure between 0.3 – 0.7*LOA.
Crew Weight

The weight of all crew members on board while racing. If not declared a default figure is calculated and listed on the certificate.

The crew shall not be heavier than the value recorded on the certificate. The owner can always declare enough margin that will put him on safe side of this requirement.   

Displacement

The weight of the complete boat in measurement trim in light ship conditions without any sails and equipment aboard. An easy explanation of lightship measurement trim would be that if the boat is rotated upside down, everything that falls out shall not be on board.

Jumper

Select "Yes" if the mainmast incorporates jumper struts.

Carbon mast

Select "Yes" if the mast is made of carbon.

Headsail furler

Check this box if there is a headsail furler used in association with one headsail only.

Mainsail furler

Select "Yes" if there is a mainsail furler in the mast.

Dacron sails

Select "Yes" if the mainsail and all headsails are made of woven polyester.

Spreaders

Insert number of spreaders

Runners

Insert number of running backstays and checkstays. The number of pairs shall be recorded.

Mast taper

Check this box if the mast is tapered.

Luff foil

Check this box if there is luff foil.
