🎙️ New to the class: Jacintha Love-Hamilton on why the J/70

The Lady Khumbu helm shares why she made the move into the class this season.

Tight one-design racing, a fleet that pushes everyone to improve, and a boat that’s as rewarding to learn as it is to race.

Next up in the UK Grand Slam Series is Cowes Week. Meanwhile, the international calendar continues with the second edition of the J/70 Mixed Plus World Championship in Copenhagen 🇬🇧🇩🇰

🏆 Corinthian National Champions: Calypso

Ali Hall’s Calypso successfully defended their Corinthian National Championship title at the 2026 J/70 UK Nationals, finishing fourth overall after a closely fought weekend on the Solent.

We caught up with main trimmer Benno Marstaller to hear his thoughts on the championship:

“The nationals really delivered this year giving us a wide range of conditions, from extremely tactical light winds to full planing conditions. Sunday was absolutely the highlight of the weekend, with 4 (and a bit) races in a classic Solent breeze. Going into the day with our discard already used up, we managed to sail 3 great first races, a 1, 2, 3.

The final race turned into an epic battle between us and Jeepster, knowing that if they sailed us down the fleet they would lift the Corinthian title. Despite their speed, we managed to retain the lead throughout the race, allowing us to defend the title and finish 4th overall - one point behind Lady Khumbu.”

Now into his second full season with Calypso, Benno also shared why he enjoys racing in the J/70 class:

“I think the J/70 class is one of the best there is. The one design element allows for tight racing, the level of the sailors is world class, and the socials are amazing!

As a Corinthian, competing alongside the best professional talent is extremely rewarding, and every day we learn something new. We were also recently at the Corinthian Worlds in Marseille, sailing in a fleet of nearly 100 amateur teams from across the globe - all one on start line! Even without the presence of the pros, the level of the fleet is second to none. We are already looking forward to next year in Vigo, Spain, and hope to see lots of other British teams there!”

The J/70 class continues to grow, offering some of the closest and most competitive one-design racing in the UK and on the international stage.

🗞️Final day done at the J/70 Nationals.

A breezy 20 knots and sunshine all day, with four races completed after the first race was abandoned when a broaching boat dragged the gate marks together. 🫣

The title came down to a battle between Jelvis and Jiraffe. Jelvis took the lead off Jiraffe after the second race of the day, which left Jiraffe needing to put three boats between themselves and Jelvis in the final race to take it back. They couldn’t quite make the gap, and Jelvis did enough to win overall.

Day two done at the J/70 Nationals.
While we waited for the wind to settle this morning an AP over 3 went up.
When the fleet arrived at the race course they were met with an unexpected easterly. A course was set and Race 4 began, with Lady Khumbu taking the win by a comfortable margin, followed by Sardonyx and Jelvis. The breeze was already dropping on the final downwind and starting to swing towards the south-westerly everyone had been waiting for, but it never quite filled in. AP over A was displayed and the fleet headed back to shore.
Jiraffe held onto the overall lead after today, while Lady Khumbu move up to third, just behind Jelvis.
Four races scheduled for tomorrow.

First day done at the J/70 Nationals, and the Solent gave us a real mix. Sunshine throughout, while the breeze was up and down all day, full planing one minute and winging the next.

Three races completed.Race 1 kicked off in a warm 15 knots, with Calypso taking the win, followed by Jiraffe and Jelvis. The wind eased for Race 2, which saw a tight battle between Jiraffe and Jelvis, with Sardonyx finishing in third. For the final race today, the breeze built a little again, but the racing stayed close between Jiraffe and Spencer into the finish, just ahead of Lady Khumbu. Jiraffe leading as we head into day 2

The fleet’s ashore now for drinks and a BBQ.

Two more days to come. ☀️
