Design 055 – Watertight Compartments and Ballast

I am getting a lot of feedback from Design 055 owners and builders as to whether they can add watertight compartments to an existing 055, or an 055 in build. And the answer is of course, yes you can.

I am happy to make the PDF scale versions of the new CNC files, which include watertight compartments, available to any current 055 owner or builder – these won't be perfect because CNC files don't have and dimensional data on them – but they give the general idea.

I do intend to make dimensioned versions of the CNC files so they can be marked out and cut by hand, but this is some way down the line at the moment as it is a very time-consuming task.

That being said, I would be happy to discuss with any builder or owner the requirements for watertight compartments and provide suitable drawings to make the modifications.

The other component of taking Design 055 beyond her original design brief is the addition of 100kg of internal ballast (4 x 25kg pigs of lead) snugly and securely fitted each side alongside the centre case. This increases the capability of the boat substantially.

You really shouldn't add the ballast without making the watertight compartments – they do go hand-in-hand. Increased capability is great, but in utilizing it the extra buoyancy is vital.
