RIVIERA - 17 Ft. Inboard Runabout - By William D. Jackson. You can do more than just wish that you had a sleek, powerful, mahogany decked runabout like Riviera. By constructing it yourself you can turn out this eye appealing 38-mph boat that will be the pride of the lake and a treat to ride in, yet spend only a fraction the price of even modest boats of the same size and power. You can further fit Riviera to your pocketbook by bargain hunting and using just the amount of trim you wish.
