Join Harken Blockheads to start receiving the monthly Blockheads Bulletin newsletter for next month’s trivia question.

Check out last month’s answer and winner below.

👉 February Question:

Part 1: If an Opti experiences 18.1 kg (40 lb) load on the boom, and is rigged with a 3:1 mainsheet purchase, how much weight will the skipper end up having to pull when the sheet reaches their hand?

Part 2: In the same wind speed, the boom on a foiling Nacra 17, with a much bigger sail, will experience 72.5 kg (160 lb) of load. How much purchase will the Nacra 17 need in its mainsheet system, so the skipper only has to pull the same weight as the Opti sailor?

👉 February Answer: 

Part 1: 13 lbs / 6 kg

Part 2: 12:1 purchase

🏆 Congratulations to February’s winner – Kevin Dunn! 🏆
