You can get many a bonkers item for sale on on DoneDeal.ie, but a man from Limerick has outdone them all.
The man in question, calling himself Jimothy Byron, has cleverly constructed an "Aquatic Sonic Ship", or ASS to you and me, to "blast from 0-6 knots in just 30 seconds".
The "lightweight composite body made from Kerry Springs water bottles, attached to an equally light pine palette" is described as "timelessly stylish" and will give any prospective owner an "astonishingly good ride". Indeed.
If you feel like buying the "River raft 4.0", it'll cost you a mere €20 and will make you the envy of the yachting elite.
