The Bayliner 3870 is a boat with a fuel capacity of 304 gallons, distributed between two fuel tanks. The tanks are built-in, with a separate vent overboard, and are usually sealed through-hull fittings, so any fuel will go overboard and not onto the deck. The built-in tanks are also vented to the outside, reducing the risk of gas fumes building up.

The tanks are portable and built-in
The Bayliner 3870 has two fuel tanks, which hold a total of 304 gallons. The tanks are portable and built-in.
Portable fuel tanks should be placed on the ground when filling them up, due to the risk of static electricity. Electrically, portable tanks differ from built-in tanks as they do not have a separate vent overboard. Built-in tanks are usually sealed with a thru-hull fitting, so any fuel will go overboard and not onto the deck. However, some older boats have fuel fills on the deck, which will drain overboard.
Built-in tanks are vented to the outside, reducing the risk of gas fumes building up in the fuel tank compartment or the top of the fill tube. They are also required by law to have a metal lip on the fuel fill hole, which is connected to the boat's grounding plate. An inspection hole allows for the confirmation that this grounding wire is present and connected.

The built-in tanks are vented to the outside
The Bayliner 3870 is a large boat, measuring over 38 feet in length. It has a spacious interior, featuring two private staterooms, two heads, and a walk-in engine room. The boat is equipped with two fuel tanks, each with a capacity of 304 gallons, for a total fuel capacity of 390 gallons.
The Bayliner 3870's fuel tanks are built-in, and they are designed with a crucial safety feature: they are vented to the outside. This external venting serves an important purpose. By allowing fumes to escape, it helps prevent the buildup of gas fumes inside the fuel tank compartment and at the top of the fill tube. This reduces the risk of igniting gasoline vapors, which could occur due to a static spark between the fuel fill nozzle and the tank.
The process of venting the built-in tanks to the outside involves directing the fumes overboard, away from the boat. This is achieved through a separate vent that is typically designed as a sealed thru-hull fitting. This design ensures that any fuel or fumes are safely directed overboard, preventing them from accumulating on the deck or in enclosed spaces.
It is worth noting that some older boats may have fuel fills on the deck, but these are also designed to drain overboard. This attention to safety is critical in reducing the risk of fire or explosion on board. The Bayliner 3870's fuel system is carefully designed and regulated to ensure the safety of its passengers and crew.
Additionally, the Bayliner 3870's fuel tanks are required by law to have a metal lip on the fuel fill hole. This metal lip is connected to the boat's grounding plate, providing an electrical pathway to dissipate static electricity. This further reduces the risk of static sparks and helps protect the boat and its occupants from potential harm.

The tanks are located behind the walk-through door in the cockpit
The Bayliner 3870 is an impressive vessel, offering a range of features for the utmost comfort and practicality. One of its standout qualities is the thoughtful placement of its fuel tanks, which play a crucial role in the boat's functionality.
The fuel tanks in the Bayliner 3870 are strategically located behind the walk-through door in the cockpit. This placement ensures easy access for routine maintenance and any necessary repairs. By positioning the fuel tanks in this area, Bayliner has made it convenient for boat owners to monitor and service their fuel system, contributing to the overall smooth operation of the vessel.
The walk-through door in the cockpit provides convenient access to the fuel tanks and the engine compartment. This door is situated on the extreme port side of the cockpit, making it easily reachable for anyone on board. While most of the engine compartment is readily accessible through this door, Bayliner has thoughtfully included a pull-up hatch in the main saloon to reach the far side of the starboard engine with ease.
The Bayliner 3870's fuel system is designed with efficiency and versatility in mind. The two fuel tanks have a total capacity of 304 gallons, and they are connected to a five-valve selection board. This setup allows for remarkable flexibility, enabling the boat operator to run each engine off its own tank, both engines off either tank, or both engines off both tanks simultaneously. Such a configuration not only ensures optimal fuel usage but also provides redundancy in the event of any issues with one of the tanks or engines.
In addition to the fuel tanks, the engine compartment also houses an 11-gallon water tank. This water tank is conveniently accessible through the hatch in the saloon, and it is connected to the engines' cooling systems. By integrating the water tank into the engine compartment, Bayliner has streamlined the overall design of the 3870, contributing to its reputation for well-engineered and spacious vessels.
Overall, the location of the fuel tanks behind the walk-through door in the cockpit showcases Bayliner's attention to detail and commitment to functionality. This strategic placement ensures easy access for maintenance and maximizes the efficiency of the fuel system, contributing to the Bayliner 3870's reputation as a well-designed and reliable vessel.

The tanks are also accessible through a hatch in the saloon
The Bayliner 3870 is a spacious and comfortable boat, with a well-designed layout. One of its notable features is the accessibility of its engine compartment, which is located behind a walk-through door in the cockpit on the extreme port side. While this provides easy access to the engines for routine or major maintenance, it leaves the far side of the starboard engine a little hard to reach. To address this, Bayliner has thoughtfully installed a pull-up hatch in the main saloon, providing convenient access to the entire engine compartment.
The engine compartment houses two fuel tanks, with a total capacity of 304 gallons, and an 11-gallon water tank. The fuel tanks are connected to a five-valve selection board, allowing for flexible engine operation. Each engine can be run off its own tank, both engines can be run off either tank, or both engines can be run off both tanks simultaneously. This setup provides versatility and efficient fuel management for the Bayliner 3870's operations.
The water tank, located in the engine compartment, is also easily accessible through the hatch in the saloon. This accessibility is advantageous for routine checks and any necessary maintenance or repairs. The water tank plays a crucial role in the boat's systems, supplying water for various purposes during voyages.
The hatch in the saloon not only enhances the accessibility of the engine compartment but also underscores Bayliner's attention to detail and commitment to practicality in the 3870's design. This consideration for ease of access and maintenance is a notable feature that sets the Bayliner 3870 apart and contributes to its overall functionality and appeal.
In conclusion, the Bayliner 3870's fuel tanks and water tank are conveniently accessible through a hatch in the saloon. This design choice showcases Bayliner's dedication to creating a boat that is not only comfortable and spacious but also highly practical and functional, catering to the needs of both experienced and novice boaters alike.
