Sailboats are designed to handle the stresses of the rigging
and the mast
. Power boats are not.
To convert a powerboat to a sailboat the costs would probably be more than if you scrapped the powerboat and bought a sailboat. Of course you can do it for much less and have a powerboat with a sail on top of it that would be almost useless as a sailboat because it is not.
A sailboat is a boat propelled by wind
in the sails
. Somewhere in the definition it is assumed that there is a particular efficiency involved. Industry and the buying
public are aware of this that is why there is something called a motorsailer
. The sails
assist, but in normal conditions they would be poor sailboats. A converted powerboat would perform much worse.
Why not convert a trawler
into a cigarette boat? There may be a time when piracy
could be common and you would have to out run them. Otherwise, the trawler
might have to be scrapped. Same principal.
