Balk rebuilds Seven Sins with longer, stronger bow

29 May 2015 • Written by Risa Merl

Balk Shipyards in The Netherlands has re-launched the Heesen-built superyacht Seven Sins after an extensive refit that included rebuilding her bow. Seven Sins has had her bow lengthened by 2.2 metres, growing the motor yacht’s LOA from 41.3 to 43.5 metres.

Balk shared in build photos with Boat International that show the intensive rebuild, which didn’t merely stretch the yacht's length but gave her a new bulbous bow designed for enhanced performance.

Balk worked with a top team on the refit of Seven Sins – Dutch designer Frank Laupman of Omega Architects designed the bow lines and naval architect Perry van Oossanen devised the hull engineering.

“The owner always had this kind of rebuild in mind,” says Maaike Hesterman of Balk Yachts.

“The owners and architects thought the [current] bow wasn’t optimal for the yacht because the bow wasn’t in proportion with the rest of the yacht.”

Not only does the redesigned bow make for a more elegant exterior profile, but the bulbous bow design improves Seven Sins’ performance.

Seven Sins now hosts an additional crew cabin, and her entire crew quarters have been renewed. While in for the refit, the yacht also had her 10-year survey, received a new paint job and had new generators installed as well a new propulsion exhaust system.

Heesen Yachts launched the tri-deck, steel-hull motor yacht in 2005. A popular charter yacht, the newly refitted Seven Sins will be on show at the Antigua Charter Show this December.
