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. The ropes around the tripod base will also be underwater so their net is nearly zero as well and can be ignored.
- Total flotation 1296 lbs
- Using half each 648 lbs
- Weight of beams 144 lbs
- Available for people and other 504 lbs
