This blog is devoted to my John Welsford designed 15' Navigator yawl Ellie. I built her in my garage over a period of 18 months and launched her in 2011. She sports a sliding gunter main, roller furled jib and sprit-boomed mizzen. Her construction is glued-lapstrake over permanent bulkheads and stringers. This blog is a record of her construction and her voyages here in the Puget Sound area and (hopefully) a useful resource for fellow Welsford boat builders.

Super simple Shopsmith bandsaw fence

Today's project was a super simple and inexpensive fence for my bandsaw. I made it from douglas fir scraps, but any good quality 2x4 scraps cut square and true will do. The only expense was for the toggle clamp from Harbor Freight for $6, part number 96233. It hooks on one side of the table and clamps to the other.






 

How to improve Shopsmith Table Alignment

I have a ShopSmith 510 and I've never been completely satisfied with the way the tables align. The tables on the 510, as you may know, each have 1-1/16" ID table tubes attached to them. The tables connect together with 1.00" OD connector tubes. The 1/16" difference results in a lot of free play, which is supposed to go away when the jackscrews are tightened. Well, no matter how hard I tightened the jackscrews or adjusted the tables, they never aligned precisely. When sliding the rip fence across where two tables join, my rip fence would catch, and clamping the rip fence there, or on a floating or extension table, would throw the rip fence out of alignment.
 
Why, I wondered, does SS use 1" connector tubes? Seems like the tables would align better if they used 1-1/16" tubing to better fit inside the table tubes. Well, there's only one way to find out.
 
It didn't take long to find 1-1/16" tubes. Home Depot and Lowes carry schedule 40 3/4" black painted steel pipe, the kind used for natural gas, with an outside diameter of 1.05". Perfect! And at $20 for a 10-foot piece, it's not very expensive either, and not a big loss if things don't work out.
 
The pipe is available in galvanized or painted black. Both types measured 1.06-1.07" diameter which is a tiny bit too big to fit inside the table tubes. I chose the black painted pipe so I could remove the paint to return the pipe to its 1.05" unfinished diameter. It would be impossible to remove the coating on the galvanized pipe. Waxing the tube after removing the paint will help prevent it from rusting.
 
After removing the paint, I test fit the pipe in each table. It fit the floating tables and extension table perfectly but got hung up in the main table. I discovered some rust inside the table tube, so I wrapped some sandpaper around the original connector tube and cleaned out the rust. Then the pipe fit perfectly.
 
I cut the 10' pipe into 4 pieces. I sized one pair to fit the main table with two attached floating tables, and another pair sized to fit the main table connected to the extension table (or one floating table).  I use those configurations frequently  so they work out better than the original SS connector tube lengths for me.  I can also use all four at once to make a 5-foot table.
 
I'm amazed at the results. Now all my tables align perfectly. My rip fence slides from table to table without catching. The fence stays straight when positioned between tables, and keeps its alignment when positioned on the floating and extension tables. The top surfaces of all the tables align perfectly. An added bonus is the wall thickness of the pipe is double that of the SS connector tubes, so they are virtually impossible to bend and do not sag like the originals did.

Photo 1 shows the original SS tube alongside the new pipe, and how the tables now align perfectly.  See the gap between the tables?  That gap can be eliminated by grinding off the little "tabs" on the main table, which improves sliding the fence across tables even more.

Three "Nearshore Anchoring" methods for small boaters

During last year's Salish-100 small boat cruise, I did a presentation and demonstration of the three "Nearshore Anchoring" methods that I frequently use.
 

Nearshore Anchoring is a way of anchoring your boat in knee-deep water so you can go ashore while keeping your boat safe and accessible.
 

The three methods I presented are:

  • The Bow-Drop method - a quick and easy method for brief lunch stops
  • Clothesline anchoring - a longer term solution that copes with tidal changes quite well
  • The Anchor Buddy - my favorite method that I use probably 90% of the time. It bridges the gap between the first two and works in most cases

Time for some new sails

Ellie's original sails are 12 years old.  They were getting wrinkled, baggy, and the batten pockets are worn out.  Time for a new set of sails!

My new set of sails were made by Really Simple Sails.  They do fantastic work and I highly recommend them.

This also gave the the opportunity to make some improvements to my original sails.  I'm not a sail designer, but I do own a copy of The Sailmaker's Apprentice, which I bought at the Port Townsend Wooden Boat festival directly from the author Emiliano Marino himself.  He even autographed my copy.  This book is fantastic.  It contains more than anyone could ever want to know about sailmaking.  

Ellie sports the gaff yawl mainsail shown on plan sheet NV12.  This rig uses a horizontal, conventional boom.  Even though I raised the gooseneck a bit higher on the mast, the boom still hits me in the head and sometimes it appears to droop.


My first improvement was to raise the clew by about 200 mm.  That'll save my noggin, eliminate the droop, and I think it'll look more attractive when it resembles the trim of the jib and mizzen's foot. I also added a bit of a curve on the foot which I think looks nice.

Next, I changed the reef lines to run parallel to the boom.  This was done so the boom remains at the same angle with each successive reef instead of angling higher with each one.  This will improve safety by keeping the boom within reach when tying in a reef.

The biggest change on the mainsail was with the battens.  The top two battens were full length and are angled relatively horizontal.  Every time I furled and unfurled the main I would have to remove or insert these battens.  This was very annoying, unsafe, and wore out my batten pockets.  My improvement is to angle the top two battens towards the throat.  Now I can drop the main into the lazyjacks on the boom without having to remove the battens at all.  I also made all four battens the same length for convenience.  In fact, I now leave all four battens in the sail permanently.  After dropping the main, I simply bundle the gaff, sail, and boom together and slide the whole affair into a sail bag.  I leave the outhaul and reefing lines attached too.  This reduces my setup and take-down time quite a bit.

My original sails are made from 6 oz cloth.  They were heavy.  This time I'm went with lighter weight 4 oz cloth to reduce the weight and because the winds where I sail are generally mild.

As for the jib, I enlarged it just a bit.  I noticed that the dimensions for the jib, as shown on the plans, do not match the jib as drawn.  The jib as drawn is slightly larger.  It's not much of a difference, but Ellie has sufficient weather helm so why not.  The new jib will have a wire luff for roller furling, as does the current jib.  This also allows me to see the foot of the jib where it was always hidden from view behind the mainsail.

And finally, the mizzen is unchanged, except I angled the battens slightly so it looks like the main sail.

Here are my sail plan drawings in case you're interested.

Full Size Template Kits for John Welsford's designs

The plans for John Welsford's designs are not drawn at full scale. One of the first tasks the builder will need to do is figure out how to go from 1/5 scale metric dimensioned drawings to full sized parts on plywood. The process usually involves drawing grids, interpreting the drawings, plotting points, fitting splines and interpreting curves. Parts can be drawn directly on the plywood, or by creating templates.  Usually by hand, unless you have experience using CAD systems. Either way, it can be a difficult, error prone, inaccurate and time consuming process for most builders.

I know because it took me, an experienced CAD user, nearly 3 weeks to create full sized templates for my Navigator build.

It's a task that every builder has to wrestle with.

Until now.




 



Working with John Welsford, I have been developing a set of Full Size Template Kits for many of his designs.

These printable template kits are available in Letter (8.5"x11"), Tabloid (11"x17"),  E (36" x 48") and in metric paper sizes A0, A3 and A4.  They are also available in roll-form (36" wide x 8-feet long).  You print the templates on an ordinary home laser or inkjet printer, assemble the pages and cut them out to create the templates.  Or take the PDF file to your local print shop and have them printed for you. Then simply trace the templates onto your plywood to get the full sized shapes.  Some kits may also include bonus items like nested parts (to save plywood), and plank drawings not included with the original plans.

These are great for anyone just starting their build.  They're a big time saver and are accurate.

Want a closer look?  You can download some free demo copies so you can see exactly how they work and "try before you buy" them.  Each kit includes detailed instructions on how to use them.  Although some pages have been omitted from these demo copies, you will still be able to see what is included in the full versions by looking at the table of contents and the page arrangement diagrams.  You will be able to print a template, assemble it, test it, and see how it all works, all for free.

Template kits are available for Navigator, Pathfinder, Sei, Tender Behind, Pilgrim, Longsteps, Scraps, Sherpa, Walkabout and Scallywag (coming soon).  Other designs are in work.  CNC cut files are also in work.

The template kits are now available for purchase as an instant digital download from Duckworks.  Here is the link: https://duckworks.com/plans-by-designer/john-welsford/

Daysailing Videos

Here are some videos I made from some of my local daysails.

During the summer, I daysail out of Everett, Washington once or twice a week on a regular basis. I've daysailed well over 1,000 miles here alone.

Possession Sound is an interesting place to sail.  It's got shipwrecks, whales, a navy base, the largest marina on the west coast, a large osprey nesting ground, a river estuary loaded with crab and salmon, tricky tides and currents, State and County parks, an indian reservation, beautiful views of mountain ranges all around, a private island, passenger ferries, and an island with sandy beaches that make you think you're in Hawaii.

I hope you enjoy these videos.  I plan on making more.  I'm a complete beginner at video making, so I apologize in advance for that.  But I hope you enjoy them nonetheless.

How to make a Sleeping Platform for Navigator

This is my design for a sleeping platform for my Navigator  I really like how these turned out and how well they work.  My son and I slept on these for a week during the Salish-100 cruise and they worked perfectly, so I’m excited to share them with you.

The platform occupies virtually no space when stored away and provides a sleeping area for one or two people when in use.

Stored position

The photo above shows the platform in its stored position.  The two panels store flush on the cockpit sole.  Note how the panels fit up against the keel batten, the seat fronts and the aft end of the centerboard case.  This locks them securely in place so they cannot move at all when you walk on them.

Sleeping position

This next photo above shows the panels in the sleeping position.  One or both can be used.  The panels are strong.  You can sit, lay, and even walk on them without breaking them.  Note there is a gap between them but it does not adversely affect their use.  In fact, it provides access to drop or retrieve small items into the footwell.  But be mindful not to allow them to slide together because they would lose the support provided along their outboard edges.

Underside

Here is a peek at the underside of one of the panels.  They are made from two pieces of plywood.  The underside piece of plywood is 1/2” thick and the topside piece of plywood is 1/4”.  The combined total thickness of 3/4” matches the thickness of the keel batten, making it lie flush when stored which eliminates any tripping hazard.  The dark strip along the edges is just a piece of felt that I glued on to protect my seat tops from scratches.

Construction
 

To make these all you’ll need is some ¼” and some ½” plywood.  The upper ¼” thick piece is cut to size and shape so it fits on the cockpit sole right up to the keel batten, right up to the seat fronts, and right up to the aft end of the centerboard case (see the first photo).

The lower ½” thick piece of plywood is cut to fit inside the footwell at seat-top level. In other words, right up to the front, back, and side of the seat top footwell opening.

The upper piece will be larger than the lower piece, assuming your seat-tops overhang the footwell.  If they don’t overhang, this entire project probably won’t work.

Attach the two pieces of plywood with glue and screws, but when you do you will want to bend them to a curve to match the contour of the cockpit sole.  You can see the curvature in this photo

Contour to match cockpit sole
 

A little bit of sanding and painting later and you'll be ready for some comfortable overnighters.

Tim Ingersoll from Superior Wisconsin recently completed his sleeping platform for his beautiful Navigator Freidlor



Said Tim:

"They really took very little time to put together, when I put my mind to it. I oversize rough cut the 1/2" ply and simply placed that on top of the seats, then reached underneath to trace the curve of the seat edge. Once that was cut to shape, the 1/4" ply simply needed to be cut to fit in the sole of the boat, which was easy to measure out. Simple and fast."

 

"I didn't use felt to protect the seat tops, but am trying the rubberized paint under the lip and on top of the 1/4" (which will be the floorboard). I'm hoping that gives me a little grip under my feet and helps keep it in place when placed as sleeping platform. I do hate to recommend until I've had a chance to see how it holds up...but we'll see."

Here's wishing you many comfortable overnight adventures, Tim!
