SB20 Cowes Week & Grand Slam | SB20 Class

SB20 Cowes Week & Grand Slam


Cowes Week, which takes place at the start of August each year is the biggest yacht regatta on the planet with up-to 1,000 yachts, 40 classes and 8,000 sailors taking part. It is also one of the oldest running sailing regattas. The SB20 has a unique format in that the first four days of Cowes Week (Saturday-Tuesday) are the UK Grand Slam. This is a 11-race series with three races per day (two on the final day, Tuesday).

Sailors who want to, can continue for the rest of the week (Wednesday-Saturday) racing in the Mini Slam, with one longer race per day. Teams competing in the full week will therefore have two results. Their SB20 Grand Slam result (which includes one discard) and their SB20 Cowes Mini Slam Result (again there is one discard).

Entry For Cowes Grand Slam and Cowes Mini Slam

You can enter either/both events at Enter Cowes Grand Slam & Mini Slam here. The Grand Slam is referred to as the “SB20 mini series” on the entry page.

Cowes Mini Slam Social Programme

Thursday (19:30)- Class Supper at the Folly Inn (order from the standard menu and pay on the night)


Competitors can arrange berthing any where they choose. Our preferred venue is Cowes Yacht Haven as it is in the center of the action, failing that Shepard’s Wharf, is the next closest. There are also marina facilities at East Cowes Marina (across the River),  and UKSA (bit further away but also has accommodation on site). We advise early booking as they will all fill up.

Polo Shirts

Shortly before the event the Class Secretary will offer competitors the opportunity to purchase SB20 Grand Slam branded UV resistant Sports Polo Shirts.
