as a simple 30-foot dive winds up being much longer than expected as the wary fish swims away or in large circles . This is when divers make the mistake of taking a bad shot . With a poorly placed shot , the fish is not slowed and will quickly wind the two lines together , which will significant wasted time back at the boat to untangle .
Here is what I suggest . Do not rush the second shot , and don ’ t be afraid to make up to 3-4 dives to get into exact position . You goal is a head shot , close to the lateral line where you have a good chance of β€œ stoning ” the fish .
Bluewater divers are constantly developing new floats . While everyone agrees we need them , few agree on a common design . On our first record-breaking trip to Guadalupe Island in 1982 , 14 bluewater divers brought along 14 different floats . We soon discovered that highprofile floats created too much wind drag , which prevented easy towing . Small floats had inadequate flotation , and large floats , such as red-eye buoys , caused speared fish to rip free
when they hit the end of the line .
Streamlined lifeguard floats were the ideal compromise because of their low profile , streamlined shape and low drag . Using several floats produces a graduated pull against fleeing fish , not a sudden shock .
Three lifeguard floats are sufficient for the biggest fish . They must be filled with highdensity foam . Hollow floats implode , popping like a balloon at 40 feet , while buoys filled with low- density ( two-pound ) foam , crush at 80 feet . ( Foam density and strength is measured by weighing a cubic foot of expanded , cured foam .)
Use eight-pound , polyurethane , closed-cell foam , cured with equal parts of liquid . Make sure the liquids in this two-part system are heated to 70 degrees Fahrenheit . Mix small batches ( paper cup size ) with a whisk bent from a clothes hanger and turned with an electric drill . Mixing larger quantities risks overexpansion of the curing mass , up and out of the buoy and onto your floor .
Equip each of the two buoys closest to your gun with an 1ΒΌ-inch-diameter ABS plastic tube , running down the center of the float and exiting toward the rear . Pour foam around it , and later
