tube diameter questions???

[jpn]

I have noticed in the marina that some RIBs have bigger diameter tubes than others....in the 4.8-5.4 meter category....

All I want to know is what's the advantages/disadvantages of bigger tubes?

Should bigger be better with regards to tubes?

[martini]

Bigger tubes will give you more buoyancy, higher freeboard, better protection/shock absorption. Downside would be less internal beam/deck space plus anything else I haven't thought of

Plus more comfort for anyone sitting on them during a passage. Downsides would be more costly to buy and more to polish/clean.

I was about to start calculating the surface area of a cylinder but I won't. I'm still recovering from the time I started calculating fuel consumption

And oil. Have you considered a drug habit? It might be cheaper to run.

Harder to climb over to get back in the boat
