A golf course bunker drainage system has been developed that is a modular structure taking the form of a plurality of porous bunker paver blocks formed of material exhibiting vertical and horizontal infiltration rates at least the same as bunker sand. The plurality of porous bunker paver blocks is disposed as a boundary layer between a bunker subsoil bottom surface and overlying bunker sand, allowing rainwater to drain into the subsoil, with excess rainwater directed away from the bunker sand. The use of bunker paver blocks also maintains the integrity of the bunker shape and prevents movement of sand and other materials along steeply sloping bunker sidewalls.

A hat with multifunctional bill portion has a sheath portion and a top sheath attachment portion is fitted over bill of a hat that has been trimmed to fit. A plurality of screws attach the multifunctional bill portion to the bill. The sheath has two magnets and an alignment portion to removably hold a bill tool such as a knife in place. The alignment portion fits within a matching finger portion of the bill tool and helps stabilize the tool within the multifunctional bill portion during use. A variety of bill tool portions may be selected to match a specific use such as knife, bottle cap opener, divot tool, wrench, screwdriver, etc.

A bottle for storing grass seeds, soil, and/or fertilizer used for filling a golf divot is provided. The bottle includes a bottom section having a base and a perimetrical sidewall extending therefrom to an open end to define an interior. A pair of bosses extend outwardly from the sidewall at the open end. The top section has a perimetrical edge and a top surface with a spout extending therefrom for discharging the contents of the bottle. A pair of latches that extend from the perimetrical edge and pivot downwardly to engage the bosses to secure the top section to the bottom section. The bottle can also be part of an assembly that includes the bottle and a holder.

A golf tee setting device comprising a top side, a bottom side, a first lateral side, and a second lateral side is provided. At least a portion of the top side is stair-stepped having two or more flat surfaces at different heights wherein one or more of the flat surfaces includes an opening extending through the tee setting device to the bottom side and configured such that a stem and a head of a golf tee may pass through each openings. At least a portion of the first lateral side of the tee setting device is stair-stepped having two or more flat surfaces at different heights wherein one or more of the flat surfaces includes an opening extending through the tee setting device to the second lateral side and configured such that a stem and a head of a golf tee may pass through each openings.

The present apparatus includes a towel that is detachably connected to a clip and/or a marker. In various embodiments, the towel includes three layers: a first layer for cleaning, a second layer connected to the first layer, and a third layer that acts as moisture barrier between the first layer and the second layer. In some embodiments, the towel may be detachably connected to a clip via an embedded magnet, such that the towel may attach to a user's clothing for easy use.

A golf utility device includes upper and lower baseplates and a ball alignment tool. The alignment tool is mechanically coupled with, but rotationally independent of, the upper and lower base plates. The alignment tool includes an upper surface with an arrow. Before putting, a golfer places the golf utility device on the green behind a ball that has been circumscribed with an annular ring, removes the ball, calculates the line of play, and aligns the arrow therewith. The ball is then returned to the green with the annular ring aligned by the arrow on the alignment tool. A golfer subsequently aligns his putt using the alignment of the annular ring. Additional golf tools may be attached to the upper or lower baseplates, including, but not limited to, a ball marker, a divot repair tool, a range finder, a spike wrench, a golf tee, and a fidget/focus device.
