Actually, we have a guy in our fly fishing group that does that. He has a table on the top part to put stuff or even rest a little. He has been fishing with us for years and about 4 years ago his health turn out to the worst but he is still fishing. The guys with the large rafts that will float on thin water took him fishing the last day so he could cover more water. These guys are guides so he got the first rate service a paying customer will get but of course for free.
