The liturgical vessels that pertain to the use of incense within liturgical worship are the "thurible," also referred to as a "censer," and the incense boat -- the object which holds the unburnt granules of incense.
The name "boat" comes with reference to the particular shape this vessel generally took -- which is indeed that of a ship or boat (see above). In saying this, it must be noted that there were different manifestations of this vessel in terms of shape, with some being more cup-like and others taking on more the shape of an actual ship-like vessel to some greater or lesser degree.
The examples shown immediately above are fairly common to the twentieth century, especially within the English speaking world, however if you were to look to Europe, especially places such as Italy, you would find another form that is, to my mind, more noble and more practical.So where might sacristans or parish priests find it today? Modern variants are available from suppliers such as Adrian Hamers or from Italian suppliers such as Artesacra Candotti. With regard to searching out other Italian suppliers, a hint would be to search on "navicella," which is the Italian word for this vessel. Evidently antique offerings can also be found if this is of interest.
Having handled and used all of the forms that have been shown in this article, I can attest to the fact that the model in question is, in my own estimation, the more noble and the more practical and I would encourage you to invest in one for your parish or chapel.
