This is the first of a series of tutorials about a catamaran i built back in the 90s. building a boat, something big enough to live on and sail off over the horizon is a dream i had for years.. 2012 xstream 18ft jet boat clear title, tunnel hull design with less than 100 hours on boat. powered by 454 standard bore, new 9 to 1 hyper tech skirted pistons, new aluminum rectangular port heads, roller rockers, 629 solid lift cam, offenhauser 4500 aluminum intake, 4500 holley dominator, 10qt. oil pan, milodon high volume oil pump, msd ignition w/6al box.. My goal in designing the pro tunnel was a hull that generates maximum aerodynamic lift in a boat meeting the gt pro weight requirement of at least 650 lbs. (boat, motor and driver), and with an expected top speed of 45-50 mph..
The fcc is an all-welded hunting and fishing powerhouse with a purposeful design and the unrivaled durability of a crestliner boat. from the aluminum center console to the hull’s wood-free construction, and all the way back to the jet-powered engine, you can confidently go where other boats can’t go..

All of the boats shown here are all welded marine aluminum. except for the duckboat, all have tunnels for jet outboards but may be used with propeller drive outboards. we have 17 and 18 foot boats, flat bottom boats, semi-v hulls, 56 and 60 inch wide bottoms. all of the boats in the photos are currently in stock, available for sale..
