This example indicates a substantially lower ratio for the 36 BBL coolship. At the lower ratio, the wort will cool considerably slower. As a result difference in cooling rate between the two coolships, the inoculation rate and ratio between microorganisms will may differ.
Designing a coolship for homebrew volumes may result in a coolship that does not appear similar to its larger companions. To get as close to the 1.73 ratio of the 36 BBL coolship with our 10 gallon example, the dimensions would have to be as close to a cube as possible with dimensions approximately 1.1' x 1.1' x 1.03'. This still only gives a SA:V of 4.9 sq. ft. per cubic foot. A homebrewer desiring a more shallow vessel may insulate the coolship to slow the cooling rate although this may affect the inoculate rate. A typical homebrew-volume boil kettle is closer to the larger coolship (estimated 1-2 sq. ft. per cubic foot) and insulating the kettle when using it as a coolship may slow the cooling rate closer to that of a commercial-volume coolship.
::Wort volume = 1122 gallons = 150 cubic feet.
::Surface area of the top surface of the wort (w x l) = 100 sq. ft.
::Surface Area to Volume ratio = 100/150 = '''0.67''' sq. ft. per cubic foot(22.0 cm<sup>2</sup> per L)
:Example of a 10 gallon coolship:
::Wort volume: 9.35 gallons = 1.25 cubic feet.
::Surface area of the top surface of the wort (w x l) = 6.25 sq. ft.
::Surface Area to Volume ratio = 6.25/1.25 = '''5''' sq. ft. per cubic foot(164 cm<sup>2</sup> per L)

==Commercial Coolships==
This table is based on data collected by [https://belgianbeergeek.be/2016/11/27/coolship-shows the-yeast-over-koelschepen-en-beestjes/ Belgian Beer Geek] on the characteristics dimensions of various commercial coolships in lambic breweries(sources noted below the table). The volume of the coolships has been calculated from the dimensions, and therefore it is slightly larger than the practical filling volume. Surface area:volume is calculated for the top surface exposed to air for both the maximum fill and the approximate batch sizes as well as the total surface area (including the walls and bottom of the coolship). Some breweries use multiple coolships at once. When multiple identical coolships are used, numbers in parentheses following brewery names indicate the number of coolships used and the volume given is the total combined volume of these coolships. For brewers who prefer ft<sup>2</sup>:ft<sup>3</sup>, 10 cm<sup>2</sup>:L is equal to 0.305 ft<sup>2</sup>:ft<sup>3</sup>.

<nowiki>**</nowiki>These coolships were used to cool wort to an intermediate temperature (~50-60 C) before finishing cooling with a Baudelot chiller, rather than for inoculation. They are no longer in use.
<nowiki>***</nowiki>The Black Project coolship is a single vessel with a divider allowing the coolship to be half filled with the depth and exposed surface area remaining the same as if it were completely filled.
<nowiki>****</nowiki>The coolship at The Referend Bier Blendery is a single vessel divided into two unequal compartments. This allows the coolship to be filled with three different brew sizes while maintaining the same fill depth and exposed surface area.
