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.
