The choice of the boat :
For the first boat that you are going to put in a bottle, I advise you to choose an easy boat to build, such like a tuna boat,
a monohull sailing dinghy, or - a little more difficult - a two-masted schooner.
You will have plenty of time to carry on more sophisticated models after you have had pratice in building some of those ones.
The choice of the bottle:
According to the boat chosen, it is necessary to select the most suitable bottle :
- For a traditional sailing ship, use a flask or a bottle.
- For a monohull sailing dinghy, choose a light bulb or a laboratory phial.
It's up to you to choose the "bottle" according to your artistic inclination,
but it is necessary to get and maintain a certain harmony between the boat and the bottle.
The transparency of the glass:
When you are choosing your bottle, you have to watch out for its transparency and particularly for its magnifying effects that you may encounter with too thick glasses like those of whisky bottles, because they distort the image of the boat. The trick is to insert
a graduated rule in the bottle and judge of its distortion through the glass.
The easy way is to introduce a rule into the bottle and to judge through glass, of its deformation.
The choice of the scale:
You have chosen the boat and found the bottle. Now, you have to estimate the size of your model, so that it can be inserted through the neck of the bottle and occupy a good percentage of the interior volume of your flask.
Do not forget to take into account the level of the sea, which generally takes 15% of the available height.
