>>11532670Which aspect of boatmaking? A significant amount of it is hands-on craft, a rudimentary and embodied engineering not science.
>>11532717>Why cant we build boats or submarines which do not require refursbishing the hullsSalt water is caustic and aggressive and makes things melt if they don't oxidize first. Metals interact with each other in funny ways in the ocean. Hulls build up static charges. Composites show exactly where they are weak or have bad seals by delaminating.
>Why do these living creatures attach and sabotage our boat materials?Hulls make convenient terrain. Get scraping, squid.
>>11532949>Can't we make a boat outer hull out of oil or a material which live things won't stick to and salt wond corrodeIf epoxy composites won't stop barnacles, it's unreasonable to assume that synthetic rubber would.
