All you need to know ahead of the Prada Cup semifinal.

The official competition to select the Challenger to face Team New Zealand in the America's Cup match has reached its knockout stage as Luna Rossa take on American Magic in the Prada Cup semifinal.

With the round robins done and dusted, the two remaining challengers face off in a best of seven (first to four wins) race to determine who will take on Ineos Team UK, who booked their place in the Prada Cup final by being the top team in the round robins.

The losing semifinalist will see their America's Cup dream end.

The main story coming into the semis will be the state of American Magic's AC75, which underwent severe repairs after its dramatic capsize in the first week of Prada Cup racing.

The Americans will be a relatively unknown prospect, having only a few days of practice time after re-launching Patriot 2.0 on Wednesday.

Terry Hutchinson's crew were the top challenger in the World Series event in December and were the only team to beat the defenders Team NZ.

However, it was a different story in the Prada Cup round robins where American Magic were winless, including two losses to Luna Rossa - suffering a capsize in the second race to put them out of the water for nine days.

The Americans will be hopeful of regaining the speed they saw right before their capsize, where they were one leg away from a win before tragedy struck.

Meanwhile, Luna Rossa have had a relatively up and down campaign thus far.

They looked like they could've beaten the British in the final round robin race last weekend but made a few costly errors.

Ultimately, it always comes down to speed and which team has made the right improvements to their boats.

The battle between Luna Rossa's dual helsmen and American Magic's Dean Barker will also be fascinating, especially during the race starts.

Schedule

There are two races scheduled each day on Friday, Saturday and Saturday. The first team to claim four wins will move on to the final. If the score is tied at 3-3 after the weekend, then the teams will have a break on Monday and return on Tuesday for the seventh and final race of the semifinal. The first race each day will kickoff around 3.15pm.
