Designer's Notebook: Notches for longitudinalsThis discussion refers to sheet plywood boats built by typical plywood on frame methods using athwartship frames at frequent intervals. For clarification, our definition of the term chine and sheer follows. The chine is the longitudinal wood member backing up the junction of the bottom and side. The sheer is the longitudinal at the top of the side planking and backs up the junction with the deck, if used. Again, to further narrow this discussion, we're assuming the boat is a flat or vee bottom with flare to the sides; the sheer line is outside the chine as seen in plan view. Frame notches can be precut before mounting the frames on the building form or after they are set up. Most builders prefer to pre-notch but it makes little difference; hand beveling while on the building form will usually be required. The patterns may show the cut outs in the frames that are required but don't automatically assume these are the exact size. Check the width and thickness of the stock actually being used and alter the notches to match. In most cases the precut notches will need to be angled while on the building form so it's usually preferable when you are precutting notches to make them undersize and trim as required when fitting the chine in place. We usually notch for battens after the chine and keel have been faired to receive the bottom planking. Then notch the frame the precise thickness of the stock being used. Very little if any fairing of the batten will then be required. We use a portable circular saw set to the required depth to notch frames for the battens, a router also works well. Since frame notches for battens may require and angle a swipe or two with a wood rasp may still be required. Select the lumber with care, particularly that for the chine and sheer, good vertical grain stock properly dried and free from knots or other defects is imperative. Sized to the plan specifications, the chine and sheer longitudinals should be at least a foot or so longer for trimming to fit. ChineSpring the chine member around the boat lapping over the stem and transom. It's nice to have the chine fit against each frame securely, but it seldom happens. Typically the chine lands securely against the frames in the aft section. In the forward section the chine must twist, a bar clamp tightened on the chine will provides a "handle" to give leverage. The side of the chine may not land securely against the side of the frame, it will probably protrude. However, the chine must solidly fit into the frame notch. The portion that protrudes must be removed during fairing. Consider carefully; the side planking must have a solid landing on the chine side and the bottom must also firmly contact the chine. Notch the frame as required so the chine protrudes so this can occur. Cut 4" or so off the end of the chine for use as a guide. Hold this block against the chine with end butting to the frame, then mark the contour for the notch required and do the same on the opposite side of the frame. Saw the frame notch and recheck with the sample block. If the fit is not precise, use a file or wood rasp to clean up the notch. Take care that the side frame does not project past the chine as this will tend to create a hard spot and mirror through the plywood planking. SheerFrame notches for the sheer are marked with a portion of the sheer member as described for the chine. Again adequate landing must be provided on the sheer for the side planking and deck (if used). Boats that have considerable flare to the sides and a sheer profile of an arc may need to have considerable material removed in fairing. In some instances, the faired sheer in the forward section may be almost triangle in shape. Notches in frames for longitudinals is not difficult if you think in advance. We'll repeat it again. The mating planking must land securely on the logitudinals. |

I was looking for a project that I could work on with my daughter, but I wanted something that would keep me interested as well as her. As a kid at the cottage, I had a three point sea-flea, which gave me great enjoyment and freedom on the water... So for Christmas of 2005, we gave her the plans for the TNT.
Kaitlyn and I started the project in Jan of 2006. The goal was to have it ready to launch by our summer vacation in July of 2006. We made it, but some of the paint was still drying the night before the launch.
Both of us enjoyed the process and spent many happy hours together in the garage working on it. This project gave me an opportunity to be with my daughter and teach her how to use tools safely. Also, that hard work, patience and planning can produce wonderful results.
The TNT has been named Freedom and after a summer of running with an 1962 18hp we are looking for a 25hp, as the boat does not go fast enough for my daughter. Also, there are two other TNT boats on our lake. It is wonderful to see three of these boat out together having fun.
Here are some pictures form our completed TNT... Photos

Well, the last WebLletter finally got me to put together some pictures of my Glen-L Zip design, "Nine Lives". She went in the water July of 2006 and I'm just getting her ready to go for this year.

Forty-something years ago when I built my first small boat, there was no need for an electrical system. My 1960 40-horse Johnson outboard didn't even need a battery - when you wanted it to start, you pulled (about 3 times) on the rope, and away you went. We called it an "Armstrong Starter".
Things have changed. Today, even the smallest boat needs at least a rudimentary 12-volt "house" electrical system to run things like lights, bilge bumps (and the stereo). There have been a lot of questions on the Forum recently about electrical systems, so I thought some folks might be interested in what I did with my Jet Squirt. Perhaps I should add that when I started this boat I made a personal commitment that when and if I ever sold it I would be able to look the buyer in the eyes and say, "This boat may be home-made, but it meets all US Coast Guard (USCG) and American Boat and Yacht Council (ABYC) requirements, just as if it were built by a big boat company". I did some homework, and found an excellent reference book, "Boat Owners' Mechanical and Electrical Manual", by Nigel Caulder (about $40 at Amazon). I recommend this book highly. While what I've done here is specific to my boat, the process is pretty generic - with more electrical devices you just need more circuits and perhaps size the wire differently.

Hi Gayle,
I have the plans and the beginnings of one of your boats. Never having
built a boat bigger than a child's toy, my friend and I will attempt
and succeed at building the Tahoe with a few variations; approx 2 feet
longer, 2 seating areas forward, none aft; longer deck and around
windshield, and last but surely not least, power it with a 12 cylinder
Jaguar motor that will be converted for ocean/lake use. Wish me luck and
a steady course. The last owner and person who began the boat is not with
us any longer and was a personal friend. His dream was to build this boat
and we will see it through for him. This may take a while due to dollars
but not for heart, for we accept the challenge. Enough drama; he
wouldn't have liked that!

Subject: Squirt finished project
Date: 12 May 2007
Dear Sir or Madam,
I'm writing to inform you that I have just finished building a
Squirt, from your designs. I was given the plans as a Christmas present
five years ago by my parents, when I was fifteen, and soon after I
started building. It took an awfully long time, as my time was occupied
with many other things: exams, university, boarding school, to name but a
few, and so inevitably the boat was often put to one side. It is the
first boat I have ever built and consequently there were many occasions
where I had to undo my efforts thus slowing progress further, yet I
continued. And now, finally, she is finished! Though she is not of a
professional build quality, she is sturdy enough, and I am a proud and
pleased man.
A few particulars: I have modified the design slightly to allow a large
dog to be able to sit in the rear comfortably (sounds strange I know, but
our Labrador loves the sea). She has a ten horsepower two stroke engine
and is able to reach speed of approximately 20 knots with two people on
board. The runners underneath her are very shallow, just enough to grip
the water. This means that cornering is slippery yet exhilarating, and
certainly gives one a huge burst of adrenaline. Though she doesn't
like waves, she is remarkably stable, and surprisingly comfortable.
I would like to congratulate and thank you for a successful and (by the
appearance of your website) a very popular design.
Once again, thanks from a very satisfied customer.
Blair Dunlop.

Have actually started the 'Ski Tow'. It's been 44 years since
I built the 'Missile', and this is what I've been hankering
to do ever since. Business life and mechanical interests took over in the
intervening years, restoring cars & building race karts, but nothing
quite compares with building one of your boats. The 'Biscayne'
plans arrived also & all the timbers to build it have come too, so
have plenty to think about, and intend to get totally immersed.
The Furniture Joinery owner who organised the Hoop Pine for the
structure is a business friend, & asked what the timber was for. When
I said it was for a wooden boat, he said his lifelong dream has been to
build a Mahogany boat, so guess what we did for the next hour or so?
Logged on to the Glen-L site. He is enthused!
It has been interesting to see you all when you published photos of
yourselves, thanks. Til later,
Ron

MONACO / Rich Coey / Modesto, California
Launched the boat on April 28th. It worked perfectly, gets on plane
almost instantly with almost no bow rise. A very smooth dry ride even
through choppy water. It ran 55 mph with four people and a full tank of
gas according to speedometer on board and friend in bass boat along side.
Should do even better with a lighter load. Carbureted 350 chevy, 1:1
velvet drive, 13 x 16 prop at 5000 rpm. Total build time was 934 hours.
Could not be more pleased with the looks and performance of this boat.
Thank you for a great set of plans.
Rich

Dear Darla,
I want to thank you for your emails concerning my recent boat-plan order. I appreciate knowing when it was shipped and how to track it. I also enjoyed reading your news letter. It's always a pleasure buying from someone who is organized and has genuine interest for their customers. I look forward to "shopping" with you again!
Sincerely,
Paul Allen

Thanks Gayle,
Make no mistake, I scrutinize the plans, the photos, and the newsletters
every month. The latest newsletter was a knock-out. These boats are
beautiful. I will probably build one. But I love small, fast and
beautiful. Nothing beats a 16' racer. I went so far as to buy Naval
Architecture books to design my own, thinking "I'm an Engineer,
how hard can it be?"
Jeez! Rocket science doesn't bother me but... ya gotta have style
for boats.
Looks like the Biscayne 18 for me. What the heck, a couple of friends along for the ride won't hurt. I used to build engines for road race teams, a turbocharged, inter-cooled 400 small block ought to get it done.
Thanks for getting back to me so quick.
Bill
