Overview

The challenge with the Annapolis Wherry Tandem was to retain the essential qualities of its famous predecessor, the Annapolis Wherry.  Known all over the world for its perfect, quiet elegance, the Annapolis Wherry is one of the most popular sliding-seat wherries of all time.  Much of its success is a result of what it DOES NOT have:  a lot of extra bulk.  That means it doesn't have much payload, either:  about 325 pounds.  That's not enough for two adult rowers.

We wanted to do more than just lengthen the Annapolis Wherry and cram in two sliding seats.  So we have created a tandem wherry that is extremely fast with two strong rowers, fast enough to win races like the smaller single Wherry does.  It also functions as a single with room for an adult passenger.  And of course you can row it all day as a single if you don't have a skilled sliding-seat mate.

Switching between tandem rowing, passenger, and single rowing modes takes just moments:  wing nuts hold the sliding seat rigs in place.  We also offer an optional cane seat that drops into place in seconds for a passenger sitting astern:  parasol and picnic basket could also be a welcome addition.

Annapolis Wherry Tandem builders will fall into a couple of categories.  Obviously, many strong two-person teams will seek it out for exercise and racing.  (The stability of the wherry type makes it perfect for rowers new to the sliding seat.)  Many builders will mainly use it as a single, but with a passenger aboard.  The 650-pound payload (including sliding seat units) means that any combination of adult or kid passengers will be comfortable.  A third category will be rowers who need a lot of payload, that also has the speed of a long-and-narrow wherry type.  You'll find those builders "beach cruising" along rivers and bays in their Annapolis Wherry Tandem, their gear packed in dry bags strapped to the frames.

Performance matches the original Annapolis Wherry, though of course the scale has changed as the length has been stretched two feet (beam and depth remain the same).  With two rowers aboard, top speeds are definitely in the "racing" category.  And in skilled hands, that speed can be maintained in rough chop or swells, making this a great open water racer.  The bow has enough volume to get up and over waves, and the lapstrake planking helps knock down spray.  The Wherry has a very dry ride. John Harris reports of his experience in the AWT, "Other than a little drip off the oars, I've yet to take on any spray in the boat, at all." Tracking is very strong in all conditions, light or heavy.  We wondered about installing a rudder, but tests in wind and wave found that small, occasional corrections by the stroke oarsman are all that are needed to keep going straight.  A rudder would be extra weight, drag, and bother.  

The Annapolis Wherry Tandem is designed around the excellent Piantedosi sliding seat units. You will also need two pair of  9'6" sculling oars with this boat.

As a single, you definitely notice the extra weight compared to the stock Annapolis Wherry.  The Tandem is still fast and fun, but all things being equal, the small single Wherry is faster with anyone who weighs less than about 210 pounds.  Especially in windy conditions, where the additional two feet of length make themselves known.  Thus, if you will almost always row single and without a passenger or heavy gear, build the single.

The Annapolis Wherry Tandem is intended for first-time boatbuilders. Despite the beautiful and sophisticated shape, we have gone to tremendous trouble to make the boat easy to build.  The computer-cut okoume planks are assembled to length using "puzzle joints," which ensure fast and accurate alignment.  The computer also drills all of the holes for the copper wire "stitches" that hold the planks together temporarily, saving hours and increasing precision in the assembly.  The frames drop into mortises we've cut for you in the bottom panel, so you really don't need to own a tape measure to build this boat!  The planks are drawn up to a beautiful and traditional wineglass transom.  Fiberglass reinforces the bottom panels inside and out, and epoxy saturates the entire structure for longevity and low maintenance.  This is our exclusive CLC LapStitch™ technology that has launched thousands of boats.

What builders are saying

My Annapolis Wherry Tandem is great. It is surprisingly stable and rowers, both novice and expert, have been zooming happily up and down the river. It is very fast, much faster than our canoes, kayaks, or our electric boat. It was also new for me to row a boat that glides so many times its length compared to traditional rowboats that row like they are in molasses.

I have just built an Annapolis Wherry Tandem and I was happy and surprised to find out that it weighs only 82 pounds instead of the 90 pounds, or more, that I expected based on what I saw on your website. It is a beautiful design, and the customer that I built it for is very glad to have it!

I am really satisfied with my Annapolis Wherry Tandem kit, a great kit and an amazing boat.  I have had it on the water four times now and each time I get multiple inquiries and even more compliments!

My daughter and I recently finished our Annapolis Wherry Tandem. We named her, LA LUNA. We had a great time building her. She had her maiden voyage out on Nimbus Lake in Sacramento, California. Thank you for designing a great kit and for all of the help from your staff.

I really love my Annapolis Wherry Tandem. So far, I have stayed mostly inside the protected embayment next to Pier 40 in New York City as I get comfortable in the boat. But even in the embayment, there is often plenty of wake action from the ferry boats during rush hour and the ever-present commercial traffic on the Hudson River. The wherry handles all of that easily.

I had a good time building the boat. It wasn't for myself, but for my boathouse, so I made a big push to get it done quickly. The kit was really first-rate, and I was amazed at how perfectly all the parts were cut. I particularly loved not having to scarf the panels, nor drill hundreds of holes for the stitches! The manual was excellent, and especially important for a project of this size. CLC's reputation for top quality is well deserved.

I'm looking forward to another project in the not-too-distance future, I hope -- perhaps the Oxford Shell.

Just wanted to say thank you. I have finished my Annapolis Wherry Tandem and it was one of the best experiences of my life. The CLC staff is amazing. You should all be proud of the great work you do. The products are top quality. I was never disappointed. Now all I want to do is row, . . . and build another boat.

Frequently Asked Questions

What is LapStitch Construction?

CLC'S LapStitch™ Construction

Patent No. 6,142,093 

Our system combines the unquestioned grace of lapstrake hulls with the proven ease of stitch-and-glue construction. The strength of the LapStitch™ joint is such that the designs require comparatively little fiberglass or fillet work, making them especially easy to build.

Lapstrake hull shapes evolved over millennia. Many would suggest that the type reached a high-water mark with the Viking longboats, but the actual building method was little changed right up into the 20th century. Planks were riveted together, and the technique required prodigious skill on the part of boatbuilders.

Over the last few decades, the advent of modern adhesives and high-quality marine plywood brought about the first major innovation in lapstrake building methods: "glued plywood" lapstrake hulls. This method of planking produces very strong, stiff, and beautiful hulls that never leak. This is progress, to be sure, but glued lapstrake boats still require molds and arcane joinery skills. It isn't a process suited to amateurs.

In 1997, Chesapeake Light Craft developed a way to build lapstrake boats without molds or complex "rolling bevels" on the lapstrake planking. Using sophisticated computer design software, we are now able to devise hull shapes that will assume a round-bottomed shape without a jig or "torturing" of the wood. A special "rabbet," or groove, is machined into each strake so that they are self-aligning. They are wired together just like a stitch-and-glue kayak. When these joints are filled with epoxy, the result is a remarkably stiff and strong hull that is visually indistinguishable from traditional lapstrake planking.

LapStitch construction is featured in these CLC boats:

After more than 15 years of development, the evolution of LapStitch™ has reached the stage where we can render complex lapstrake hull shapes in complete confidence without "strongback" molds.  Chesapeake Light Craft can design and build for you LapStitch™ hulls of any shape or size.  

How do I order this kit?

Click on the Buying Options tab the top left of this page and follow the directions.

If I buy one of your boat kits, what else will I need?

Chesapeake Light Craft kits contain all the parts and materials you need to build the boat. The kit includes pre-cut parts, hardware, epoxy, fiberglass, plans and instructions. Our standard kayak kits also have the seats, hatches, bulkheads, footbraces, and the deck-rigging. About the only thing kits don't include is the final finish: paint or varnish. Your boat's color scheme is entirely up to you.

You'll need a few ordinary tools, like a cordless drill, a decent 5-inch sander, and for most boats a wood plane. You'll need disposables such as sandpaper and paint brushes and mixing cups.

You need a workspace a couple of feet bigger all the way around than the boat you want to build, and you'll need to be able to maintain temperatures between about 55 degrees F and 95 degrees F during steps when epoxy is being applied or curing. Since a lot of boatbuilding gets done during winter, we've written up some tips on how to heat a cold space cheaply, easily, and safely.

How much does this boat weigh and how much can it carry?

The weight and payload of this boat, along with other statistics such length and beam, can be found under Specs in the Specifications section, which is just below the lead image seen at the top of this page.

Can you send me the plans digitally?

Sorry, but until digital rights management technology for marine architectural work catches up to that used for books and music, we are unable to transmit digital plans. Currently, only study plans and manuals can be sent digitally.

Capacity, Speed, and Versatility

Large Capacity

With a maximum load capacity of 650 lbs, the Annapolis Wherry Tandem has plenty of room for three adults and a child. Or a family with kids and dogs. The Wherry can carry whatever you need to move.

Competitive Racer

Despite its large capacity, the Annapolis Wherry Tandem, is designed to move effortlessly through the water. With the sliding seats installed, a pair of rowers can move this boat at speed. She glides with grace.

Easy to Switch Units

Switching between one rowing unit for a solo rower to a pair of rowing units for tandem only takes a few minutes. Wingnuts make it easy to loosen the seats and tighten them securely.
