2018 PHRF Handicaps for J/Boats Models
May 14, 2018
The relative speed of various models of J/Boats is listed below in seconds per nautical mile. The table shows relative predicted speed of each model compared to one of eight “control” J/Boats, each in a different speed range, whose actual performance has become widely known in many PHRF areas over many years. The “control” J/Boats used in this comparison are the J/44, J/122, J/35, J/29 (Masthead outboard), J/80, J92, J/30 and J/24. Assumptions are that:
1. Except where noted as “One Design”, each model conforms to all local PHRF definitions of an unmodified “base boat” with a base 155% genoa (depending on local regulations).
2. Maximum spinnaker size (without penalty) conforms to local PHRF regulations defining base spinnaker size, except where One Design definition of spinnaker size accompanies the speed prediction shown in the table below.
3. Wind strength averaging ten knots is used to predict relative speed. Because most J/Boats have similar characteristics in different wind strengths, this is a valid way to predict speed differences versus one of the “control” boats over a wide wind range.
4. PHRF numbers are recommended for each boat relative to the “Control” boat listed, based on two separate types of courses.
5. Crew Weight: Our rating recommendations for PHRF numbers for J/Boats models designated as One Design DO NOT include crew weight limits. It is assumed that PHRF crew weight limits, if any, shall apply equally to all types of boats racing in a given PHRF area, and that One Design designation only applies to the boat, rig and sails. Therefore One Design Class Rules regarding crew weight should not apply when racing PHRF if these rating recommendations are used.
PHRF ratings of the “control” J/Boats may vary somewhat from one PHRF area to another. The PHRF numbers shown are what seem to be typical for these boats nationally. If the PHRF number shown here is different for the applicable “control” boat in your area, apply the difference to the relative rating of the J/Boat you are handicapping. For instance, if the J/35 rates 66 in your area rather than 72, as shown on the attached table, the number for the J/Boat you are rating would be six s/m less than what is shown.
If you have specific questions or would like to discuss these recommendations further please contact either Alan or Rod Johnstone by completing an inquiry form (in the top or bottom menu) or by calling the J/Boats office directly at 401-846-8410.

J/121 recommended standard base ratings above are for inshore racing. The relatively small water ballast assist system of the standard J/121 is designed to replace the righting moment on the rail of approx 4 crew members. This system promises to simplify crew organization and to boost participation in sailing events for owners.

Your Next Boat
|Welcome to the Spritboat Revolution|
J/Boats with retractable carbon bow sprits and large, asymmetrical spinnakers now dominate the world of sailing.
Another reason sprit boats work better is the crew doesn’t have to fight the boat and sails downwind in strong breezes. The center of effort of the spinnaker is further forward and lower with more slope to the sail’s leading edge and with a leech that’s more open because the trailing edge never has to function as the leading edge of a symmetrical sail. All this means that: When gusts of wind hit the sail, the boat tends to become better balanced with a neutral helm; the back edge of the spinnaker opens up rather than cupping; and, the bow has a tendency to lift rather than bury. So the energy of the wind is transmitted into acceleration forward rather than a frightening round-up and knockdown. These boats make, what used to be terrifying conditions, just another great day to zip across the bay.
Current J/Boat Models
J/70 is all about FUN! It’s J Boats’ first ramp-launchable sportboat. With a lifting keel, this speedy one-design sails 6+ kts upwind and planes over 15+ kts downwind. Over 1,300 boats are sailing in 20+ countries within the first five years after launch. Simple to own and easy-to-handle, J/70 can be sailed by all generations.
J/80 is the gold standard for international sportboat competition and training, thanks to its unique combination of stability, speed, durability, low maintenance and age-friendly deck layout. It even has a full-length V-berth and 12-foot-long cockpit. Discover why J/80 has become the “family one-design.”
The J/88 hits the sweet-spot in the performance sprit range. This mid-size 29 foot family speedster is fast, fun and stable with the security and comfort of a sit-in cockpit, inboard diesel, weekending interior and onboard head. She’s small enough to be single-point lifted without having to rely on the boat yard.
The J/95 is a break-through, performance daysailor/weekender that sails in less than 4’ of water. The modern hull design is combined with a low VCG lead keel, retractable bronze centerboard, twin rudders, and wheel steering. The result is a fast and stable boat that’s a dream to steer and easy to single-hand.
This sleek, speedy, one-design 36 footer has brought the fun back into sailing. The large cockpit, easy-to-tune carbon rig and 60” wheel permit the crew to sail fast and in control, going to windward at 7+ knots and hitting double-digit speeds downwind. The J/111’s spacious interior is comfortable for family weekending.
A new 40' to sail with half the crew! The best short-handed J ever…. capable of winning on any race track while also excelling in daysailing and weekend mode. Here’s a boat that redefines sailboat racing as a recreation and shared adventure with friends, reducing the focus on athletic short-course W/L racing.
The J/97E is the first ‘J’ in 25 years (under 32’) to combine standing headroom for family cruising in a high-performance design. Its modern innovations make sailing easier: an asymmetric spinnaker, retractable bowsprit and a furling, non-overlapping jib. J/97E accommodates more crew than it takes to sail her.
The J/112E is the newest addition to J Boats’ “E” series of high performance cruising yachts. The “E” is for elegance and evolution in performance cruising design. Why settle for anything less than sailing with comfort, style and speed. This 36 footer is designed for today’s active sailing family.
The J/122E is the world’s most versatile 40-foot performance sprit cruising yacht - with comfortable live-aboard accommodations and an unmatched racing record on three continents. Whether sailing offshore or near home, J/122E’s stability and ease-of-handling make it a true joy to daysail, cruise or race.
