Mirror Cutter or Spitsgat Cutter

One of the popular motor yacht types in the Netherlands is the cutter. The cutter is characterized with a flowing lines plan, round bilge or multi-twist built and equipped with a straight transom or a Spitsgat. Below we try to explain the differences.

Round bilge

The underwater ship is built smoothly round, so the underwater ship does not slap on the waves. Together with a support mast with a support sail of several square meters, the boat hangs in the wind and the cutter sways a lot less. In order to obtain greater hull stiffness, round bilge joggles are also built.

Round bilge joggled.

Joggling is the name for pushing, or “joggling,” a steel plate through 2 rollers, by which the plate obtains a kink with raised edge, which slides over the underlying plate when welding an airframe. This method of construction is labor intensive em gives a hull a lot of stiffness. Hulls become relatively expensive, termeer considering most cutters are not used for sea voyages, and therefore jogging is excessive.

Multi-knuckle truss

Multi-twist bilge is a more economical way of round bilge construction, where the plates are not rounded but welded together in small bends. Since many hulls are delivered as cut packages, it is very easy to incorporate into such a package. As opposed to round bilge, what there one has to work from a whole plate.

Mirror Cutter

The term transom cutter indicates that the vessel is equipped with a straight transom, the none inside the aft cabin, where mostly the owner’s cabin is situated, it provides a lot of space. Enough for a French bed, and in many cases a generous wet bar.

Spitsgat cutter

Again, the term pointed hole refers to the aft work of the cutter. A pointed hole has the advantage that the ship releases the water faster, i.e., can obtain a higher speed. It also has an effect on the cutting effect of the rudder, and the spit-hole cutter will maneuver better than a transom cutter. Both forwards and backwards. And lastly, this method of construction also holds up better on the high seas, with wind at your back and a support sail on. A transom cutter would have a tendency to want to run out of rudder, while a spit-hole cutter holds better.

In short, a round bilge joggled vessel equipped with a spit hole and support mast is the ideal seagoing vessel. And can one for touring on the inland waters, and indicatively taking on the bigger water, compare to a multiknik transom cutter. Which is a lot cheaper price-wise.
