According to the U.S. Coast Guard regulations, an 18-foot powerboat with installed fuel tanks is required to have at least one Type B fire extinguisher on board. If the boat is equipped with a larger engine or additional fuel tanks, more extinguishers may be necessary, depending on the specific circumstances and requirements. It’s important for boaters to check local regulations and guidelines to ensure compliance.

Multiply the two numbers together. That would be 180 square feet.
18' X 16' = 288sq ft 288 sq ft / 9 = 32 sq yds 32 sq yds X $0.65 = $20.80
1 yard = 3 foot so 16 foot by 18 foot = 51/3 x 6 yard carpet 51/3 x 6 = 32 square yards of carpet. At 0.65 per square yard this is 0.65 x 20.80 per square yard.
The weight capacity of a 4x6 pressure-treated wood beam depends on various factors, including the type of wood, the load distribution, and the span between supports. Generally, a 4x6 beam can support approximately 1,000 to 1,500 pounds per foot when properly supported and loaded uniformly. For a beam that is 18 feet long, this would translate to a total weight capacity of around 18,000 to 27,000 pounds, but it's crucial to consult specific engineering tables or a structural engineer for precise calculations based on your scenario. Always consider safety factors and local building codes when designing structures.
