Although we are no strangers to refit work, the decision to cast our own keel - from design to finished product is definately one of our crazier projects! A task that felt huge when starting, took up all our free time during spring. If you are further interested in our DIY keel casting, check out our channel or check out or playlist https://www.youtube.com/watch?v=st9sX4bne1k&list=PLHgGaw1dpS58b1uu5Wrq5HHw01zU335fv where we have gathered all our keel related videos!

Day 2 of the owner's event Dragonfly Days 2024 offered a bit of wind and rain, but still some very nice sailing, during the Kangaroo Race. In the afternoon we had people visiting the Elvstrøm sail loft in Aabenraa, some people visiting the Dragonfly Yard and a seminar with Oceanvolt. In the evening we ended the day with another seminar, where our dealer from TAN Services in Dubai told about his trip from La Grande Motte, France to Dubai in a Dragonfly 40. Please enjoy this video from the 2nd day of the event!

You have probably noticed that I am sharing my first videos about how I prepared myself and my boat for my circumnavigation. These videos were originally in Dutch, and I am now creating new versions with more explanation and an English voice-over to take you with me on my preparation journey. In May, after cyclone season, I’ll be sailing on toward South Africa and sharing new videos from sea again. Thank you for following along and being part of this journey. If you’re curious about preparing for a circumnavigation — mentally or practically — ask me anything in the comments. I’d love to connect.

UK Sailmakers uses very powerful 3-D CAD/CAM software for sail design, which create virtual 3-D molds that can be digitally sliced into two-dimensional panels that when joined back together re-create a full-size version of the designed mold. Thanks to powerful 3-D graphic renderings, designers can see how sail fit around the spreaders and shrouds as well as make sure the clew height and sheeting angles are right. They can also analyze how a main and genoa work together to make sure the boat stays balanced. What we are looking for is a sailplan and sail shapes that put the maximum driving force in precisely the right place to produce a perfectly balanced boat – and with the least amount of drag. Pat Considine, UK Sailmakers’ chief designer, goes a step further and uses Fluid Structural Interaction software, called FSI for short, as a virtual wind tunnel for refining sail designs and sail construction. FSI calculations are used to test proposed designs and cloth choices to make sure they are not built too strong (too heavy) or too weak (too light) for their expected loads. The FSI calculations will predict whether a design and construction will keep its shape properly as the rig bends, halyards are tightened and sheets are trimmed. Shown rotating in this video are two renderings of a Tripp 47 mainsail design. The side-by-side comparison shows the sail with no backstay tension and with max backstay trim. The FSI software allows Pat to rotate the two designs together to study their shape from any angle. In this case, Pat needed to be sure the draft would not move too far aft as the sail was flattened; likewise, he had to make sure the draft was not too far forward when the backstay was eased completely. The FSI program has made extremely accurate predictions of how specific sail designs will perform once made and trimmed in a variety of wind speeds. These tests ensure sails will meet the performance needs right out of the bag.
