On the drawing board: Pedal boatFor years we've had requests for human powered "pedal" boats, and for years we've had to say that we didn't have them. Well that will soon be remedied. The "Pedal-It" will incorporate readily available bicycle parts. It will be a pontoon hull with a rudder fabricated from pipe and fiberglass. We will have more on this project in our next WebLetter. There is no due date as yet. After the test model is completed, the drawings will be finalized, instructions written, and drawings and instructions proof read. Click here for photos of the beginning stages of construction of the test model. Note: The Pedal-It is now available. See the Boat Design Catalog/Special purpose designs Sliding Rowing SeatWe have been getting a number of email questions concerning "add-ons" for existing boats. Things like "center console", "sliding rowing seat", and "flying bridge". We don't have flying bridge plans, but their construction is covered in our book "Boatbuilding with Plywood". Several builders have adapted the Console Skiff Console Patterns ($17.00) to their boats, and the Sliding Seat plans ($23.00) for the Sculling Skiff are available separately and have been popular with many builders for use in their rowing boats. The copy below is from our "Book of Boat Designs" Build your own sliding seat rowing rig. It's easy and fun with Full Size Patterns and simple step-by-step instructions. Built of wood and other readily obtainable materials, the unit weighs only 19 lbs. Designed to be independent of the hull, it can be lifted out as a unit for transporting. Clog spacing and angle are fully adjustable and the seat rolls with nylon sheave wheels on an aluminum rod track. (NOTE: These Plans & Patterns are included with the SCULLING SKIFF.) Sliding Seat Plans & Patterns: $26.00 The Hardware Kit includes all of the hardware pieces described in the plans and patterns package that are required to build your own SLIDING SEAT assembly. Complete with: stainless steel bolts, nuts, washers, screws and threaded rod, plus track, sheaves, heel cups, instep leathers, and sculling oarlocks. Why run all over town looking for the right pieces? Let Glen-L do it for you. UPS shippable, weight approx. 5 lbs. Shipped F.O.B. #05-206 Sliding Seat Hardware Kit: $121.46. The New Glen-L Book of Boat Designs will be available within the month.
Feedback: RenegadeEmail: Hi Gayle, A couple of years ago we contacted you looking for plans to build a tournament style ski boat. The closest hull you had to offer us was the Renegade. We liked the hull shape but thought the boat in general had a dated look. We purhased the plans from you and it took a whole year to finish the boat. I am sending you a couple of pix to show what we did to the plan. We followed the plans exactly to build the hull to the deck line and then put our own idea of what we thought a more modern deck should look like. We used a straight inboard installation using a 350 Chev engine 265HP, and a Borg velvetdrive hydralic transmission. We built the boat strickly for the purpose of watersking so the seating might not appeal to everyone. I am sending you a couple of photos of the boat, if you wish more we have a complete set of pix as we built it following most steps. If anyone is interested in this type of boat we would be glad to send them photo's and give them any assistance that we can. You can give my e-mail address to anyone interested.
Thanks for a great plan Update on Mark Dietel's Thunderbolt ProjectDear Barry, Attached are some photos of my completed Thunderbolt project. I have also include some verbiage if you wish to include it in the "Building the Thunderbolt" Newsletter you published last year. (WebLetter 10) Paint & Completion: My Thunderbolt was completed with application of the topside paint on April 28 2000. The top and bottom is painted with Interlux Brightside, the bottom being teal and the bottom white in color. I had my doubts about how a garage applied roll-on paint job would turn out, but this Interlux stuff is amazing. It goes on with a rough appearance with many small bubbles, but flows out to a smooth finish as if it were sprayed on. The only trick is to make sure any accessibly large bubbles are rolled out before the paint dries. I highly recommend this paint, very economical considering two quarts is plenty for the entire craft. Engine & Drive: Power is derived from a stock Mercruiser 260HP V8 with Velvet drive transmission running through a Casale V-Drive. The engine was acquired on Ebay, a factory new unit never installed in a boat. This cost me several grand, but after adding up the expense of everything required to do an automotive conversion, it seemed quite reasonable. The heavy and bulky Mercruiser cast iron exhaust manifolds were replaced with Glenwood logs. These were installed upside down in order to clear the rear decking. I stayed with the stock Mercruiser cooling system, which has two outlets for each manifold, one for hot water which flows through the thermostat and the other for bypass water. Originally the hot water dumped into the manifold and bypass water into the elbow (I assume this is to keep the manifold at engine temperature). I reversed the connection on the Glenwoods to keep the manifolds cool. Hope to be able use use the manifolds as a handle for water skiers boarding the boat. The original 1" water hose was replaced with 1/2" to accommodate the fittings on the Glenwoods, still there seems to be more than enough cooling capacity. The V-Drive is a In/Out Casale unit coupled to the Velvet Drive through a short drive shaft. The In/Out unit is left locked in gear, as neutral and reverse are obtained with the Velvet Drive marine transmission. Controls and Instrumentation: The engine instruments are new "old stock" acquired on Ebay. The controls are a used model from an older Mercury outboard, also aquired on Ebay. This keeps with the vintage theme of this style of boat. I intend to add a depth gauge, as I already struck a rock with the prop and had to replace both the prop and shaft. First Run: First run was on April 29, 2000. Because the engine is new and I did not want to take any chances, the speed was kept down to around 35 mph. Very suprised at the steering balance and response. I've always been told that inboards do not handle as well as outboards or I/O's, but I love the response of the Thunderbolt. Steering is light and responsive, unlike the I/O's I have owned which feedback considerable steering torque at speed. The overall balance seemed excellent, without much tendency for the bow to raise during hard acceleration. Should make an excellent ski boat. I wish to thank Barry and all the folks at Glen-L for their timely help during the construction process. Shop talk: Scarf sledby Mark BronkallaI wanted a quick and highly repeatable way to cut scarf joints for the chine, sheer and battens. The methods listed in the books (hand saw, router jig, hand plane, etc) did not appeal to me. I wanted to do the cuts on the table saw. This sled is modeled after a cross cut sled, but with a pair of fences added for positioning the stock. All of the wood is from the scrap bin. Dear Guiseppe: My experiences concerning the Glen-L 30by Markku KukkamäkiDear Sir, Gayle Brantuk from Glen-L forwarded me your question concerning the costs of building the Glen-L 30. However, it is very difficult to answer satisfactorily because I made my boat from fiberglass and I started some 25 years ago. It was last February when one Italian asked me my experiences about my boat. Because my answer to him is not too personal I think that I can forward it to you as well. If you are interested in hearing more about my experieces building the boat like Glen-L 30 and my boat itself please don't hesitate to ask. With best regards Markku Kukkamäki And here is my response to Guiseppe where there is also a picture of the boat: Dear Guiseppe, I am very pleased to notice that you are interested in my experiences concerning Glen L 30. As a matter of fact I started to build my boat in 1976 when I was young, eager and short of money. However, I am happy that I started then even though it has taken all my spare time (and money) ever since. I am satisfied also that I build a boat big enough at once because boatmen are always dreaming about bigger and bigger boats. Glen L 30 is however very spacious so that even 4 to 5 adults can live aboard for weeks. On the other hand, on my boat I have full batten main, furling head, autopilot, bowthruster and rather powerfull engine so that I can handle it very easily only by myself alone. (Now you understand why it has taken all my money). Because all this equipment I have collected during last 20 years, the weight of the boat is nearer 7 tons than 6. It makes that in very light winds it is rather slow but when it starts to blow 6 -10 m/s, six knots is easy and stability is good, you can sail for hours without touching rudder. Heeling is modest 7-12 degrees, mostly less than that. If you take one reef to main and furl somewhat headsail you can easily sail in winds from 12-15 m/s. Construction time and costs are very difficult to estimate because I have made some modifications and improvments all the years I have had the boat. Not because the boat itself was bad but because I have seen good solutions in other boats and originally I made it with very little money. The plans were very good and if you follow them and don't do any modifications building Glen is easy. If you make compromises for instance in finishing you can build the boat rather quickly and if you have money enough to buy rig and all kinds of fittings and equipments factory made you save a lot of time. The place where you build your boat should be large enough and sheltered so that you don't need to worry about your working tools and so on. If you afford to invest for good tools at once it will save you alot of time and it is pleasure to work. I made my boat from fiberglass but plywood is very good too with epoxies and other good glues and paints. Plywood may be even easier and faster to build. I suppose that costs are higher here in Finland than in Italy especially concerning boating gears. I think that with 15,000 ECU you can have a boat which sails, 30,000 ECU you can have a boat with good basic equipment and live aboard convenience, and with 50,000 ECU a boat of superb finish, fine fittings and full inventory of devices (that kind of a boat in Finland costs 120 000 ECU). But it takes some thousands of hours to work (perhaps 3000) and from two to four years depending on your abilities concerning money and help from your friends and especially from your wife. If you are interested in hearing more, please mail and ask. Unfortunately I have not many pictures about my boat but I can take them and also otherwise consult when needed. Aith best regards Markku Kukkamäki Recent email:
HELLO:
ANSWER: The Trailer Plans are for boats within a certain size
and weight limit. The supports for the boat are not detailed.
This information is contained in the book How to build Boat Trailers which comes
with the plans. It is likely that one of our trailer plans
could be used, but there are no specific details. Below is a special feature... Stroke the webMASTER. These comments have been collected the last few weeks. I could have posted a lot more, but I don't want to brag.
