It's great to provide information; even better to provide correct information. Exposed Drum Cable SteeringWhat is it? how do you install it? where can you get it?Racing-type exposed drum steering is ideal for smaller boats such as the Glen-L TINY TITAN, SUPER SPARTAN, PICKLEFORK, XP-8, CLASS RUNABOUTS, and similar boats where there is no room under the foredeck to run other steering systems. MountingMount the steering drum in the center of the dash. The vinyl covered tiller cable threads in and out of holes on the steering drum. The tiller cable should be of equal length on each side of the drum. Wrap each half of the cable 3 to 4 turns around the drum in opposite directions. Holes are cut into the coaming to accommodate the coaming pulleys, with the chrome flange mounted on the outside. The coaming pulleys should be located so that the cables run parallel to the dash when threaded through the pulleys. Clamp a piece of scrap wood (1" x 2" x 4' approx.) to the motor, parallel to the transom, as close to the pivot point of the motor as possible. Fasten the tension springs with eye straps to the outside of the cockpit, side deck, or other suitable position, at least 4" forward of the transom. Temporarily tie or tape the steering pulleys equidistant toward either end of the piece of wood. Thread the cable through the coaming pulleys and steering pulleys, and clamp to the tension springs. Turn the steering wheel and check the turning radius. Move the pulleys in or out and try again until desired turning radius is achieved. NOTE: For the fitting process, twine can be used, instead of cable. Now that the length of the steering bar is determined, purchase a piece of steel or aluminum channel, or flat stock. (NOTE: On the Tiny Titan, we used 1" x 1/4" steel channel.) This will be fastened to the motor as close to the pivot point as possible. Secure steering pulleys to the bar, thread cable, and clamp to tension springs. There should be tension on the cable; pull the final spring, approximately 1" extension, before clamping. Trim cable to length. Where can you get it?Glen-L offers a kit that provides for a complete system up to the steering bar, including: tiller cable, coaming pulleys, swivel pulleys, cable clamps, tension springs, and eye straps. Wheel is 12" diameter in gleaming bright metal spokes with black cushioned, easy-grip wheel. Comes with mounting bolts, 4" aluminum drum which is mounted on the dash, with cables exposed.

Feedback: Jet drives in the TNTTerry MortimoreIn the latest WebLetter you asked for information on installing a jet-ski package in the TNT. If you look in WebLetter number 5 you will see our first boat the TNT called MR. Bean which has a power package removed from a very old Sea-Doo (1960's vintage). Other than changing the angle of the transom to match the pump flange it was a very straight forward installation. It has proven to be a very safe and practical power package for the boat. The only down side is that in anything larger than an 8" chop, the pump cavitates quite a bit. I think that if you were to use a more modern pump and duplicate the water intake area that the original jet-ski has, this problem would be eliminated. What angle was required for the jet? Do you have any idea what the HP rating is? How did you do it? I hope the pictures will help, it was just getting dark here (forgive me for not crawling under the boat). The engine has been removed to install a modern CDI ignition system, the original was points. In any installation I would try and reproduce the water intake area so that it is the same as what was on the donor personal water craft. Hopefully this would help avoid any cavitation problems. Riviera update: Our Riviera is away in the garage for the winter, soon I will be starting to build the frame work for the upholstery and that will be done by the spring. Terry Mortimore Feedback: Jet drives in the TNTThomas NilssonHere are some pictures of my TNT equipped with a Kawasaki 440-engine and water jet from a jet ski. It's really safe and fun without any visible engine/prop. I made the water intake in fiberglass and I used all the useful parts I could from the jet ski, like gas-tank, exhaust, cooling, electric-start, steering-cables and so on. Because of the jet, it's easy to go all the way in to the shore even for the kids without having to worry about any prop. Next season the water intake is to be modified (optimized) a bit and new paint will be applied. Thanks for good plans and frame kit. Thomas Nilsson Follow-up email Thu, 31 Jan 2002 Here are some answers to your questions. The length of the engine and jet in the jet ski is about 115cm, and that is way too much for this boat, so I had to shorten the driveshaft as much as I could. I made the shaft about 30cm shorter than it was in the beginning. I still needed some 13cm more space and moved the seat 13cm forward, then it was possible to squeeze the engine in. The distance from the transom to the front end of the engine is 84cm, measured on the bottom, the angle of the transom is the same as in the plan, the jet is pointing a little downwards. The hatch over the motor is not raised at all, it's almost 2cm space on top of the motor. The speed is limited to 12 knots with a driver of 75Kg, and that is because the water intake is bad, the impeller cavitates after 1/3 throttle. That is the reason why I am modifying the intake for next season. I made the intake so small and steep simply because of the lack of space after the compact installation (engine close to jet). Now the intake will begin under the engine instead of behind it, this will give a much smoother way for the water to get in to the jet. You can see the modifications I made on the boat to fit the engine, on the attached picture. I promise to send you an email when the new intake has been tested this spring/summer. Another thing to mention is NOT to forget where the force is concentrated in a jet installation; it is the front bearings of the driveshaft that has to take all the force. That's why I have a thick stainless frame going from the bearing-housing to the transom. See engine picture in last mail. Please add me to your project registry! Regards, Note: Ideally a jet is installed in a vee bottom boat. Because of the interest in jet installations and the plethora of used jet motors now available, we are looking into the possibility of designing a TNT-size boat for a jet. Will keep you informed in future WebLetters. Steering problem - Rudder cavitationSubject: Bonanza Hello, I have a Glen L Bonanza built in 1963 by my father and my grandpa. There has always been a problem with turning. When making left turns the bow tries to go down. My dad said it has done this since the first time it was driven. He has talked to many people about it and they can't figure it out either.. Any ideas? Thanks, Shane Answer:
Although the above copy does not mention the symptom described by Shane, it is caused by cavitation and is a fairly common problem. Feedback: Sea Knight, Zip, and UtilitySubject: Past project photos. Attached are three new photos I thought you might find interesting. The single B & W picture is your "Utility" running with a believe it or not 35HP engine. The other two are of your "ZZZIP" and are two different boats. They are identical so both pictures represent their finished appearance. The one in the water preceded the cruiser "Sea Knight" I built later and the engine was transferred to that cruiser. A 4 blade bronze 10 x 10 prop was used with this engine on the cruiser and it ran about 17 MPH with this arrangement. This is the cruiser you already have pictures of on your site. I might add that all of these boats (Built in the mid 50's) were reinforced on the bottom of the hulls by adding vertical 3/4" wide members on top of all bottom battens and keel. These members extended to the top of the frame members and were corner blocked to the frames much the same as the racing Hydros of that era. This also included the "Sea Knight" cruiser which also had a bottom double planked with two layers of 1/4" Plywood and sheathed in fiberglass cloth and resin. This cruiser was new in the spring of 1959 and sold in the spring of 1961. I saw it only once after that, in 1978, 17 years later, and it was still in use with a Vee 4 engine. I think it speaks well of the structural integrity of that hull. My upcoming second Sea Knight will be also as good or better.

suppliers Escapade ModelDear Sir. I have had on hand your Escapade Plans since 1975. I never had time to build it as is, but since I'm retired, I've made one 27" x 10" with radio control. It is very nice looking. I enclose photos. Jacques LaChapelle ConundrumAllyn had a call from someone asking questions about the Console Skiff. His final question was "How does someone go to the bathroom in this boat?" Allyn suggested that he and his passengers limit their intake of liquid or wear "Depends". How do you solve this real-life problem? Feedback: TNTThis boat was built from a TNT frame kit in order to replace my older TNT. I finished the project just prior to the 2000 boating season. The boat has white oak frames with red oak splash rails and dash. I fiber-glassed the hull and deck, making the boat very solid, much more so than my old boat that was not made with these materials. I also repainted my 1988 Mercury 25, which is such a great engine I had to make the boat black to match it! The low center of gravity engine and a fin on the bottom of the boat provide good tracking and turning, so I couldn't be happier with the all-around performance. I learned of this Glen-L kit when my brother Ethan and my father first built a TNT, and we just love the safe, fast design! Luke Stryker, Shop Talk: Fairing boardsby Rhed BrownI made my own fairing boards for fairing my Rob Roy and they worked out very well. I took some pics of the process and thought that they may be of interest to other builders. Recent email:Subject: wood boat builders hello- I'm looking for a site where a boat is being built, ideally with a good deal of wood visible in the hull. I shoot for Corbis (14 years) and will be illustrating the theme of craftsmanship among other themes. I'll be happy to pay a fee for access/use of the site in a photo shoot of about two hours. If you know of a builder who might be interested, I'd be grateful for any leads. If a fee is of little interest, I'd be happy to provide reproduction quality film (35mm chromes) in exchange for use of the "set". my pictures can easily be seen at www.peterbeck.com many thanks...

1, 2002 name: Roger Jiles Comments: My father built a 19' Hot Rod design in the late 50's. We built a Glen-L 10 in the early 70's. I have been a Glen-L fan since I was a boy. Your catalog continues to capture my imagination for hours on end. Having this site on the web just adds to the pleasure. I can log on at a whim at 11:00 PM and before I know it the clock is striking 4:00 AM, and I need sleep! Thank You for a lifetime of enjoyment. Sincerely, Roger Jiles Subject: RE: Glen-L 12 Registry Barry, Thank you for your reply. Every thing about the building project has been very satisfying and well supported by Glen L Marine. The launching should occur within a week and photos (on the water) will be forthcoming. Karl Almquist Below is the result of your feedback form. It was submitted on Thursday,

February 20, 2002 name: Ron Gallfy Comments: My dad and I built a "Zip" 45 years ago from Glen-l plans and we used that little boat everywhere, lakes, bays and yes even off shore. When my father died it passed to another part of the family but I believe it had a productive lifespan of at least 35 years. Building it was a wonderful experience, in that it gave me the confidence in my abilities, the understanding of the joy of doing a job well, and finally it gave me quality time with my Dad. Small boat building is a wonderful family experience that I often recommend to my friends and I even mention Glen-L. Subject: new pictures Hi Glen-L, I have a new email address, and finally have some pictures of the sailing Foamee up on the web site. http://www.quigs.org/Foamee/sailing.html Bill Below is the result of your feedback form.

February 3, 2002 name: jerry webb Comments: Have had many, many boats over the past 35 years. The most fun boat I had was a Glen-L Crackerbox built by Otis Faulkner around 1954. Sold the boat 20 years ago, have been looking for another one ever since. Subject: Tango builder(s) in Calgary I'm building a Glen-L Tango and enjoying it immensely. I briefly met another Tango builder on Glenmore Reservoir in Calgary last summer. He invited me to give him a call if I wanted to have a closer look at his boat. Since then I've lost his name and don't remember it. He ordered the plans from Calgary & built the Tango in Calgary about 5-7 years ago. Would you be able to let me know his name/phone number? Thanks very much. We can't really look up builders by City and if he has not ordered in 5 years, he may not still be in the system. Perhaps he or someone else from Calgary who has built the Tango is reading this WebLetter and will contact Rob. Below is the result of your feedback form. It was submitted on Friday,
