Centreboard or Lifting Keel? Building an Aluminum Boat - Design Part 3 with KM Yachtbuilders

⛵️ Sail Away Weeks with Paul and Sheryl Shard 🏝
Join Paul and Sheryl for a sailing experience in the world’s top cruising destinations. Get an introduction to the sailing lifestyle, build new skills, make new like-minded friends! Cabins still available for British Virgin Islands, February 20-28, 2022.

Ever wondered about the pros and cons of a centreboard versus a vertical lifting keel? In this session of our design feasibility study with KM Yachtbuilders, we do a deep dive into keel options – how they operate, how each affects interior space and the importance of rudder depth. We consider a Bestevaer 53, look at features of a Stadtship 56 including telescoping rudders and study stability curves and polar diagrams.

00:00 Introduction
08:28 Custom vs Full Custom Yacht
10:05 Sailboat Stability Curve
16:36 Polar speed diagram for sailboats
35:58 We met up 24 years earlier?
38:35 Conclusion

Criteria for our New Boat, Distant Shores 4
– a monohull sailboat under 50 feet in length
– a pilot house or raised salon you can steer from
– a variable-draft ballasted centreboard for performance and exploring
– comfortable office space for both of us so we can work while cruising
– 2 double cabins, 1 single cabin, sea berths
– day head near the companionway with shower, ensuite head and shower for master cabin
– galley ideally near the companionway but alongside is good too, if not too far forward.
– twin wheels in the cockpit, not a tiller
– table in cockpit
– stern scoop
– stern arch with dinghy lift
