Since the many requests on information on hatches and hatch covers, I've decided to write this small article.
Besides having a safe and non leaking hull, the same is handy for the roof. Since hatches give a certain look and feeling to your boat; I like keeping them. Therefore, when the metal roof will be built on the Watergeus, the hatches will be put back. Like a boat needs to have a wheelhouse, so it needs to have its hatches, I believe!
Important for hatches is that they are fitted properly and tightened up. Wind can blow away hatches. I've seen it happening!
An example of how not to fit your hatches
Shape of hatches
Typical for Dutch barges and especially for Luxe Motors is a Friese luikenkap. These hatches had a shape of a pyramid. Depending on the width of the vessels these hatches could exist of two sides that needed to be slide into a metal top.

Rolluiken are built to easily move them by one person. Beneath every hatch is a wheel that slides over a rail. So the hatches can easily be moved without lifting. It is one of the best hatch systems available at the moment.
Rounded hatches are very light, mostly aluminium, hatches, often called 'blow away hatches'. They are very common in Belgium on spits barges. You need two people to move the hatches.

Type of hatches
Originally all barges had wooden hatches. Often protected by tar to keep them from leaking. To protect wooden hatches, a cover was used.

Aluminium hatches were lighter to carry and better to maintain. These days all commercial barges have aluminium hatches (there are a few exceptions).

How to close hatches
Depending on what type of hatches you have there are several options in securing them. Here are a few examples...
The most simple way, weld a metal stick to hold them. A quick solution, but no good for permanent use.
A loop where you put a cable through after the hatches have been slide over it. This picture shows how not to do it...
Putting a L-profile at the end of the hatches. The L-profile is attached to the den and keeps the hatches from being blown away.
And if there is no way to hold your hatches, put something on top of them...
A very unprofessional way, but efficient in some way...
Bringing light to the boat
Often the best way to have light in the boat is by the roof. You can put windows in the hatches or you can replace complete hatches by plastic hatches. Here are a few pictures to illustrate this:

When a metal roof has been built, people often decide to put back wooden hatches for the look of the boat. When placing windows, two entranced need to be made for putting windows, one in the wood and one in the metal. Here is another approach for solving this issue:

Like replacing rounded hatches with plastic ones, there is also the option to create hatches in glass. It is a very effective but expensive way. The idea comes most likely from houses.
