Your Questions Answered | IFS Multi Tradewind Sail Q&A

In this video, Peter Bresnan from OneSails Palma answers all the questions raised during our presentation of our latest development: the IFS Multi Tradewind Sail. When we introduced the IFS Multi Tradewind Sail, many questions came up about sail rigging, handling, ease of use, and the technology behind this re-invented sail system. In this Q&A session, Peter explains how the sail works, how it can be used on both multihulls and monohulls, how it can be rigged depending on the boat, how it is handled, and how it improves efficiency and ease of operation for modern yacht sailing—among many other topics. Whether you are a professional sailor, yacht owner, or simply interested in marine innovation and smart sailing systems, this video will give you clear and practical answers.
