Making Instructions (Login to see the full instructions)

Cable tie some crates together and fill with bottles. Put in a bath full of cold water.
Weigh out some objects and test maximum weight they can hold. Weigh yourself and work out how many crates you will need to stay afloat. E.g 2 crates hold 7kg. I weigh 10 stone which = 63.5 kg % 7 kg = 9 x the 2 crates = 18. So i need 18 crates minimum.
join crates together into for groups of three and two groups of four.
One layer of crates. Hinges mark where the breaks will be so it will fold up
Measure out all the floorboards. You will need 10 x 66cm floorboards.
Take out and old nails with hammer and make sure all surfaces are clean and flat
Line up four planks 5.5cm apart with one plank half way over the top of the four planks. Drill three holes for each plank and screw down. Line up a plank across the other four ends and repeat.
Line up two planks on each outer side, making sure they line up with the middle planks. Put hinges in place and mark out holes. Drill and screw down.
Add small seat planks if desired. Measure out middle of two supporting planks that are bracing the four in the middle. Place skateboard trucks in place and mark holes. Drill and screw down.
Place first layers of crates over the frame 3 then four then three. Mark out and drill holes for four washers and screws. Screw down first layer.
Fill all the crates with the bottles. Make sure all the lids are fully screwed on and pack the crates as full as possible. Put second layer of crates over the top of the other later, bottle side down so all bottles are trapped in the two crates. Cable tie all of then together so it feels strong.
Bolt on the wheels. (i did mine earlier but would have been best done last.)
The Finished raft as it would be on the water.
Flip over and folt up the sides. Tie with a ratchet strap to secure and attach to bike trailer.
Making an Oar! Cut off ends of a skateboard.
Heat the grip tape with a hairdryer and pull off. You will need to soak off the sticky stuff with washing up liquid.
Sand down all of the paddle untill nice and smooth. Then wax with natural water resisting wax.
Drill holes in a long strong wooden pole and paddle. Bolt together with two bolts for stability. Leather or fabrib wrap the pole for grip if needed.
Bike Trailer. I cut the bottom tray of a shopping trolley with a hacksaw to make a sturdy trailer to attach to the raft.
Trailer is attached to seat post rods using jubilee clips. Position trailer, thread clips around and tighten until the trailer is solid. Make sure the wheel wont get any interferance from the trailer and that your brakes haven't been effected. Attach the raft and test drive before setting off to sail!
