Pottsy, to answer your questions, yes the drums were turn side ways on the 4' wide dock near each dock end, each section is quite stable as one section but much more when secured together as one larger unit. If you need more stability on one section of dock you could add more drums or increase your width and add more drums to that width. The dock floats approx. 18" above water level and with 4-6 adults getting in and out of various water crafts it may dispers some 4-6" more? These drums work well and the sky is the limit on any design wanted.
