GP 26 (Donovan)
GP 26 (Donovan) is a 25 ′ 11 ″ / 7.9 m monohull sailboat designed by J. P. Donovan and built by W Raceboats starting in 2011.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Designed by Donovan to GP 26 (ORC box)rule. Carbon spars std. Draft is 3.5’ with keel up. Lifting rudder in cassette, opt.

GP 26 Report
Last week we showed you the new Jim Donovan designed GP 26, and here JD gives a little insight into the rule and the boat.
When I first approached the GP 26 class rules several years ago, my initial impression was, “Why would anyone want to build a boat so closely resembling a Melges 24? The strength of the Melges 24 class will surely limit the growth of GP 26 fleets”.
Since this first impression I have spent some more years sailing aboard a Melges 24 at home in Hawaii, generally in high winds. Much of this time I have thought how nice it would be to have a boat that can handle the breeze better, with a deeper keel fin, bigger rudder with more feel, rig further back in the boat to keep the bow from driving under the waves, and a couple winches to make it less painful to trim the jib and spinnaker. With my new GP 26 design I now have the platform for all of these improvements.
Closer examination of the GP 26 Class dimensions reveals a yacht with excellent potential. Although the GP 26 is approx 200 kg heavier than a Melges 24, all of this weight is carried in a deeper keel. The GP 26 has a similar displ/length ratio as the Melges 24, and the GP 26 rig is nearly 1.4 m (4.5 ft) taller than the Melges 24. Added to the package is a masthead Code Zero to boost the reaching and light air performance further.
You can easily derive that a GP 26 has plenty of power and will deliver very high performance. I am really quite excited to get this boat out on the water and let it loose. I think these small box rule yachts appeal to “individuals”; that is to say people who want to own a yacht that reflects more of what they want in hull form, rig and deck layout.
The GP 26 class reminds me of the IOR ¼ ton fleet that had many owner-built or owner-finished yachts. At the major regattas you would see quite a diversity of designs, and it was always interesting to examine the various designs and then line-up against them on the race course to see what happened. Showing up with a fast design was a major facet of the regatta that you just don’t get in a one-design fleet.
Thankfully the GP 26 bears little resemblance to an IOR yacht, and the box allows designers to explore a variety of hull forms within simple length, beam and displacement limits. My GP 26 design is currently under construction on the ground floor of Farrar Sails in New London, Connecticut. Kevin Farrar has built several racing sailboats over the years, and he decided it was time to upgrade from his 23 footer into a GP 26.

Announcing the new Donovan 26 One-Design
Stagg Yachts is proud to announce it has been selected as class manager and sales representative for the exciting, new Donovan 26 One-Design. This high-performance sportboat is an update on the already successful 26-footer created by renowned yacht designer Jim Donovan.
Mag Marin Composite Yachts of Istanbul, Turkey will serve as builder of the Donovan 26 OD, which will be very competitively priced at under $80,000 delivered to Annapolis. Stagg Yachts is prepared to accept orders for boats that are anticipated to be available in Spring, 2018.
"We're really excited to be bringing this new product to the marketplace, with its quality of build, exceptional value for cost, sportiness and responsiveness we anticipate it being a popular choice for all levels of sailors looking for a fun boat," said Brady Stagg, vice president of Stagg Yachts.
This marks an evolution of the WRace Boats GP 26 that was also designed by Donovan and built by Mag Marin. While the hull, mast, rudder and keel are the same, the Donovan 26 OD incorporates several updates that will further improve the boat's overall performance and standardize it for a one-design rule.
"While we've focused on ensuring great performance we've been mindful of the need to make it user friendly for the many club racers looking for something that's more fun to sail than what they may be accustomed to," Stagg said. "It is designed to be a very stable boat with a deep draft and generous foil surfaces so control in crowded quarters and windy venues can be maintained with ease, while having adequate sail area to ensure great performance in light air – just a great all round boat."
Mike Beasley, an Annapolis-based professional sailor, fell in love with the GP 26 from the moment he took ownership. Beasley has enjoyed tremendous success with his boat named Rattle-N-Rum, capturing the Palmetto Trophy for winning the most competitive class at Sperry Charleston Race Week 2017.
"I absolutely love the boat. I think it's one of the greatest 26-footers I've ever been on," said Beasley, who worked extensively with North Sails designer Per Andersson to refine the sail inventory aboard Rattle-N-Rum. "I always felt the GP 26 had a lot of potential. It's a great all-around boat, very versatile. We've done well in heavy air and light winds. It goes through the range with no problem at all."
The owner of Beasley Marine, who has an expertise in boat modification/optimization, made some minor changes in the GP 26 that produced major results. Many of those upgrades have been incorporated into the new Donovan 26 OD with the most notable being the addition of a square-top mainsail and an inhauler system for improved upwind performance.
Donovan, who cut his teeth with the renowned firm of Farr Yacht Design before striking out on his own, took those ideas and found several other ways to enhance his original design.
Updates include:
- Bow sprit lengthened by 800 millimeters
- Gooseneck lowered 75 millimeters
- Added topmast runners to accommodate square-top mainsail
- Added a spinnaker takedown system
- Addition of a pit winch
- Relocation and reconfiguration of some deck gear and systems to improve leads and ergonomics
"I think the modifications they are talking about with the longer bow spirt and boom are going to make this new Donovan 26 OD a real rocket ship," said Beasley, who has also captured ORC 2 class at the Storm Trysail Club's Annapolis Fall Regatta two years in a row. "This updated version of the boat will plane earlier and simply go faster in all conditions."
Serhad Ciftci, a principal owner with Mag Marin Composite Yachts, said the strength of the GP 26 fleet on the East Coast of the United States is an encouraging sign for the new Donovan 26. Ciftci noted there are eight of the original version boats regularly racing and that five comprised a class start at Charleston Race Week 2016 under the ORC rating rule.
"We have seen very competitive class sailing with the GP 26 and that will only be taken to another level when we develop a one-design class for the Donovan 26 OD," Ciftci said.
Jim Donovan, who has worked for numerous America's Cup syndicates, founded jp donovan DESIGN in 1995. The San Francisco native has been instrumental in the creation of nearly 200 designs ranging from 20-foot day sailers to 130-foot luxury yachts.
Donovan loved the GP 26 from the outset, but realized over time that it had developed "an identity crisis." Was it best suited to racing under rating rules such as PHRF and ORC or was it really a one-design?
"In hindsight, I think the boat was somewhat constrained by the GP 26 rule. Owners in different parts of the country had configured the boat differently so when they came together for a regatta we had to rate them all separately," Donovan said. "That is the main reason why we have decided to develop a true one-design with set rules and class management. We want to nail the boat down and firmly define it as a one-design."
Donovan is excited to have Stagg Yachts coming onboard to help develop the class rule and guide the class moving forward. Stagg Yachts is known worldwide for its steady stewardship of the legendary Farr 40 class and has managed several other one-design classes over the years.
