Can i use my old bath tub for a boat if i fit a outboard to it and plug the drain hole up ?

In Australia for years a 10 or 15 hp outboard has been bolted to a standard bathtub and used for a popular bathtub regatta on various rivers and such. They go pretty good, and the two person class is very entertaining. They often carry two or three spare props due to smacking into rocks in the shallows during distance events!





A performance hint is to use the flat bit as the transom, and the round end as the bow - after that modifications are minimal - oh and flat bottomed baths are faster too.

In most cases a ';cast iron'; tub would weight more than the water it displaces, so it wouldn't float........Try googling displacement for a full explanation of how this works. If you can measure the no. of gallons of water the tub would ';displace'; that's how much weight it would support including cargo (you) and equipment and the weight of the tub itself. Take the cubic feet contained in the tub X the weight in pounds or kilos that the equal volume of water would weigh, less the weights mentioned above. Keep in mind that filling the tub with splash would ad to the load......I hope this is understandable.

the bathtub by its self lacks sufficient floatation to carry the weight of and outboard and a person. but bathtubs with additional floatation are raced. fast bathtub speed boat racing began in British Columbia.





there are also bathtub raft races.





do a google search for bathtub boats and you will find a lot of sites.





hope this helps
No. First of all the deign is different..a bathtub will not glide through the water like proper boats. it'll cause massive drag and it will disintergrate if put under too much strain..a bath tub is made of plastic not steel.
Yes, but it isn't going to go very far, very fast.


They even made some boats out of concrete on the Great Lakes years ago and floated.


Depends on the displacement in the water.
With a few modifications, yes. check out this link.
