Both the Harris Flotebote Grand Mariner SL 250 (2-Tube) 2010 and the Harris Flotebote Royal Heritage 250 2009 are pontoon designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
