It all started with a boat that's a BLAST to sail!
J/70 - One Design Speedster
Easier to trailer, rig and ramp launch
The J/70 Speedster (22.75 feet) is J/Boats’ first ramp-launchable, keelboat – designed to fulfill the need for an easy-to-own, high performance one-design that’s exciting to sail, stable enough for the entire family, AND easy to tow, rig, launch and sail. Since its introduction in 2012, the J/70 has become the most prolific sportboat in the world with 1800+ boats sailing in 30+ countries. It all started with a boat that’s a BLAST to sail!
Key J/70 Features
– Large comfortable cockpit with open transom.
– Deck-stepped carbon mast for easy rigging & stepping.
– Inexpensive three sail inventory with masthead A-Sail.
– Vertical lifting keel.
– Small cabin for storage and personal privacy.
– Easy to trailer to regattas, ramp launch and store at home.
– Only 1,750 lbs so most 6 cyl vehicles can easily tow.
– Fits inside most standard garage doors!
More comfortable to sail on deck
The 11′ long cockpit and moderate height boom in the J/70 allow easy crew movement across the cockpit while tacking and jibing. For sitting and hiking comfort, mid-height padded backrests/lifelines run cockpit length, large cockpit floor mounted toe-rails for secure foot bracing and comfortable seat height and ergonomics makes J/70 one of the most comfortable small keelboats to helm. No need for hiking straps to keep you in the boat. Plus there are strict class limits on how to hike to make the boat less physical to sail.
Easy for the entire family to join in!
With standard jib/spin sheet winches, a feather light responsive helm and confidence building stability, you can enjoy sailing with friends and family more often. Juniors and seniors alike feel as comfortable and in control steering or trimming. Whether daysailing or joining in for some sunset racing, the J/70 is both exciting and forgiving. And then if you want to take it to the next competitive level, there’s J/70 competition almost everywhere on the planet.
On-board privacy, storage & auxiliary power
The small cabin below is a bonus in any small keelboat, and the J/70 cabin is just large enough to provide weather & sun protection, a place to nap and/or for personal privacy . . . essential to keeping the whole crew happy if spending a full day on the water.
J/70 International Class Association
The J/70 Class Association is a dynamic owner-based organization with professional management that oversees an active regional, continental and world sailing calendar. Recognized by World Sailing as an international class, the J/70 Class holds annual European, North American, South American and World Championship events with special recognition of its Open, Corinthian, Women and Youth champions.
The J/70 one-design class rules require a 2.5 hp outboard engine (gas or electric), plus anchor and additional safety gear. This means one can be self sufficient on the water without worrying about paddling home. Race Committees can start races on time and finish them later in the day without having to tow boats.
