Re: Islander 30 fuel tank size
Of the I-30s on YW the listed fuel capacity varies between 20-25 usg.. in any event this data could be guesswork/estimates all around. 20 is much more likely as a stock original design intention. It's just as possible that the boat in question actually has a 20 gal tank unless it has been replaced and the owner is being honest...
