Looking at building a 1:5 scale model/prototype that is big enough for 2 people to ride on in the ocean. The legs will be 20 feet long.

Got these 3 barrels for $20 each from the concrete plant.

This 3" by 3" square tube is 20 feet long and cost me $53. Tropical island prices include shipping and duty, so are usually nearly twice mainland prices.

Weights

• Barrels 20 lbs
• 3" square tube 20 feet long - 48 lbs
• 4x4 at 16 feet long - 60 lbs

Flotation

They are 54 gallons which is 432 lbs in fresh water and a bit more in salt water. The plastic should displace enough additional to float the 20 lbs of the barrel, so we can ignore that.

• Total flotation 1296 lbs
• Using half each 648 lbs
• Weight of beams 144 lbs
• Available for people and other 504 lbs
