The Seagull Striker and Martingale are a critical structural part of the forward beam on the vast majority of catamarans. They strengthen the front beam between the two bows and take the load from the forestay which is usually either attached to the beam or the longeron. In our case, we will make the forestay attachment on the longeron just behind the seagull striker. We also would like to improve our sailing range by adding an attachment for a storm sail.
The above video shows the lamination process of the front beam to longeron. We use the tip of a carbon fibre spreader as our seagull striker and make our own carbon martingale strap.
Watch how we installed our martingale in the blog post link.
