National 10 (Turnabout)
National 10 (Turnabout) is a 9 ′ 8 ″ / 3 m monohull sailboat designed by Harold R.Turner and built by JG Marine starting in 1953.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Most recent known builder (2015): JG Marine 67 Skilton La. Burlington, MA USA
The NATIONAL 10 was originally known as the TURNABOUT CLASS, built in 1953 by Harold R.Turner as a small wooden single or double handed junior training dinghy. Many boats were completed by “do it yourselfers” from kits. Fleets have been located primarily in New England and Northeastern regions of the U.S. In 1972 the TURNABOUT CLASS formally changed it’s name to the “NATIONAL 10” class. It also decided to refine the class by approving a new mold, adhering to the original wooden design as much as possible. This was accomplished by J.R.Duplin Marine with some major improvements, including aluminum spars. The minimum class weight of 215 lbs was increased to 255 lbs. to keep both the older Parker River turnabout, the woodies, and the new Duplin National 10’s more competitive.

- 10′ Navigator
The Navigator is a great knockabout small boat. Fun to row and sail, it makes an excellent ship-to-shore yacht tender. It’s also light enough for cartop transport—handy for boating on inland lakes and the inner harbor.
The Navigator is an excellent boat for general recreational use, as a yacht tender or personal watercraft. It rows very well, has good stability and buoyancy, and sails very responsively.
We personally use this boat for everything. We will carry it on the roof rack for a quick run to our favorite secret crabbing area, we tow it behind a “big” sailboat, and it’s the boat we grab for just “dinking around” the harbor on a Sunday afternoon.
The high performance option consists of easily removable bowsprit with 120% genoa jib and related hardware. It is a fast, fun little dinghy.
Are you considering using the Navigator as a yacht tender? Whether you want it stored on deck, sidemounted on a swimstep, or simply towed along behind you, we can offer advice on how best to customize your boat for the way you want to use it.

- Navigator owner #1
“I think I may still be one of your happiest customers. We’ve been sailing our Navigator for 12 years now (through 2 cruising sailboats), and my trusty tender is well travelled (incuding a car topped tour across the states and back)! You may remember me when I managed the now defunct Offshore Store…you’ve also got a shot of my wife and dog on your web site. Well, I decided to go cruising. I’m wrapping up a 2 year trip through Central America and now find myself in Miami. Now I did go with an inflatable RIB for daily use, but I just couldn’t leave my trusty Navigator behind. I’ve sailed it in almost every country we’ve cruised in. I plan on rigging up for a sail in Miami tomorrow!”
~Trevor, SV Lea Scotia (10′ Navigator)
“I have been rowing my Navigator 10 on the Puget Sound virtually every day, rain or shine, since August of last year. It is incredibly stable in rough water. It will take rougher water than I am willing or able to. My normal row is around the breakwater at Shilshole Bay Marina. I am regularly amazed at its ability to ride over waves which appear, as they approach, to be much higher than the boat. In addition to its ability to ride effortlessly over rough water, it glides several boat lengths on each stroke. It is truly a pleasure to row and I feel extremely secure rowing it in all types of weather.”
– M. S. Stern, Seattle (10′ Navigator)
“I took the 10’ Navigator out for a spin today around Lake Union and I couldn’t be happier. She rows really nice and also handled some wind and chop very well. I like the longer oars and the heavy oar locks. It was really easy to put her in and out of the back of the truck. . . I also took the navigator on a shake down row to Eagle Harbor. My overall rowing speed (3.2 mh flat water, no wind no current ) was actually faster than the Melonseed! Thanks again and see you on the high seas!”
~ Randall, Seattle WA (10′ Navigator)

1. Twelve of the best training boats Sailing schools, clubs and training centers use a variety of boats with beginners, including singlehanders such as the Pico, Hartley 10 and the RS Quba, the latter having three rigs catering from entry level to more experienced sailors. There's also a range of larger training dinghies from builders such as RS, Topper, Laser and Hartley Boats.
We decided on the Spindrift 10 nesting dinghy. As far as hard dinghies go, I am very pleased with both the stability and carrying capacity of this little boat. We have loaded it with three kids, two adults, and a bunch of gear and felt completely comfortable. Nested, it fits nicely under our boom on the big boat. I grew up as a dinghy sailor.
