6

HPR Measured Items - FO

• FO - Forward Overhang- if the bow knuckle is above the waterline, FO shall be the horizontal distance from the forward end of LOA to the point where a 45 degree angle intersects the knuckle- if the bow knuckle is below the waterline, FO equals the horizontal distance from the forward end of LOA to the intersection of the stem with the waterline

• IMS B6.10

Note: With exposed knuckle, FO is independent of trim/float condition

Note: FO = IRC BO - IRC x

7

HPR Measured Items - FBI

• FBI - Freeboard at Fore Side of Mast- the average of port and starboard freeboards measured vertically from the sheer point to the water level at the section at the fore side of the mast

• IMS B6.8

Point to Measure FBI

8

HPR Measured Items - CPW / CPD

• CPW - Chainplate Width- the distance between the centers of the bearing points of the chainplates for the upper shrouds of the mainmast

• IMS F6.3 / F6.4

• CPD - Chainplate Diagonal- the distance between the center of the bearing point of the chainplate for the uppershrouds to the mainmast centerline

9

HPR Measurement Requirements - Vcg Source

• Component Method- Full hull measurement in empty lightship condition-- Length, beam, draft, overhangs, freeboards-- Weigh boat-- Weigh keel/bulb and determine cg- Full rig measurement - plus mast weight/cg and boom weight- Full sail measurement

• Incline Method- Verified offsets file required- Incline and measure freeboards in empty lightship condition-- Weighing highly desireable- Full rig measurement- Full sail measurement

10

HPR Measurement Requirements

• Never Rated under any Rule -- Full Measurement:- Vcg via Component Method- Vcg via Incline Method

• Boats with Fully Measured ORR certificate:- Vcg (lightship):-- Direct from ORR incline/float data if boat measured in lightship condition-- Calculated from ORR incline/float data if boat measured in ORR trim IF complete

Measurement Inventory with weights and location is available-- Otherwise, new freeboards required (but not incline)- In-water: FBI and Y measured in lightship- Rig: CPD, CPW measured- Sails: Additional headsail dimensions required

• Boats with Endorsed* IRC certificate:- Vcg via Incline Method or Component Method- In-water: FFM, FAM, FBI measured in lightship- Rig: IG, ISP, BAS, BD, FSP, CPD, CPW measured- Sails: Additional mainsail and headsail dimensions required* Endorsed with scale weight or DSPM and measured hull data

IRC One Design certificates are Endorsed but not weighed and measuredThere are a few IRC Endorsed certificates based on RORC Standard Hull Data

• Talk to Offshore first- Confirm what data is on file- Confirm what data needs to be measured
