Petrel 33 is the logical evolution of her smaller sister petrel 28 , with the task to expand the horizons of cruising activity for a 4-6 person crew, raising the bar of onboard comfort, keeping the boat size under the critical (for a homebuilder) size of 34 foot – 10 meters of overall length., a “new classic” looking cruiser, sturdy, with no frills and weird solutions, ready to let you sail with a decent speed and a very good comfort level both at anchor and sailing., the starting point is the very good sailing capabilities shown by the petrel 28, so i decided to develope this hull into a enlarged design, keeping a quite narrow hull for actual standard, prolonging the bow lines for a plumb stempost; i expect to have a similar behaviour of the proven 28footer, with a tender weather helm in every situation, a very soft and gentle wave riding attitude in a seaway, and a good acceleration coming out of the tacks, i expect a little bit more speed given the longer water length ; section are moderately full at the bow, maximum beam is around 60% of hull lenght , transom sections keep a moderate vee.
Sailplan is based on a 50% area split among mainsail and a furling jib ; we kept the upwind sailing area to a moderate value, avoiding “wannabe racers” temptations; a decent sized gennaker can be hoisted on the fixed bowsprit, an obvious choice given the fact that the new generation furlers are making this sails very easy to manage for cruising crews too, adding the pleasure of sailing downwind in light airs at a decent pace, a weather situation which is quite a pain in normal mainsail + jib configurations ; in roughest situation you can hoist a storm jib on a removable internal stay fitted on a high load chainplate leaning on the forward structural bulkhead ; rig is a classical 2 spreaders mast , spreaders are 15° swept, there is a structural backstay and no structural runners, lower shrouds are doubled., deck gear configuration features classical sturdy and manageable solutions, without too many frills : 4 self tailing winches to pull sheets, halyards and control lines, 2 stoppers array on cabin top panel, 2 tracks for jib cars, so that the jib can keep a decent shape even furled, a small track for the mainsail purchase, all the control lines are led to cockpit to avoid bow walks in “spicy” situations (plans will detail how to make bombproof fitting points for lifelines too);, boat will be powered by a diesel (20-30 hp) or electric (7 kw) inboard engine fitted with a saildrive or shaft-line transmission ; this will allow to keep a decent pace while motoring in zero wind situation, or to add a good booster to sail thrust if needed; i expect to reach a 6.5 knots boat speed at 2000 rpm with a 30 hp diesel engine., rudder and steering system:, rudder is a single blade semi-compensated one with tiller steering system ; there will be two options detailed on plans: spade rudder with ss steel shaft (this solution is depicted in rendered images), and an easier to build transom hung rudder., finkeel is naca profile keel made of welded steel plates, ; ballast is made by lead poured in the keel hollows ; keel is fitted on the hull with a web of bolts on solid hardwood floors, with nuts and high thickness ss steel counterplates under the cabin floorings; keel load is carefully distributed to avoid any local high stress area., interiors and on board living:, this area marks the main differences among this 34 footer and her smaller sister; higher hull topsides and two more meters of boat make a world of difference in terms of interiors and on board comfort; we have 6 regular berths, a comfortable galley and dinette area, a decent volume for on board systems and storage, all that you need to medium-long range sailing given the size of the boat ; both forward and after cabin are closed with a small door to gain a little bit more privacy ; cabin height is around 191 cm , cockpit is quite wide, and it’s designed to be comfortable for a crew of 6 while sailing with the heeled boat too ; transom area is protected by a sturdy wooden hinged structure that can be lowered when moored to be used as a transom platform. low sleek coamings protect the forward area of the cockpit , making the primary winch basement too; toerails and good sized areas among cabin flanks and hull sheerline make going to the bow a very safe operation even when boat is heeled and in rough conditions;, building system:, given the good amount of miles sailed by petrel 28 in every sea state with very good reliability, i keep a similar structure for this project, upgrading the scantlings to cope with higher stresses; so the boat structure is a grid of plywood bulkheads and frames linked by solid wood stringers and a mixed plywood-solid wood structure forming keel backbone and stempost ; hull planking is made by 12 mm plywood, with the radiused area made by two layers of 6 mm plywood panels , all glued to the underlying structural grid , in a reliable , sturdy and easy to build system called “radius chine” ; cabin , cockpit and deck surfaces are made by 10-12 mm plywood panels stiffened by a grid of secondary stringers, solid beams and other structural elements; the hull bottom is further stiffened by a number of solid wood floors , tightly spaced in the centerboat area, where they bear the finkeel loads. all critical areas and structural bondings are strengthened and stiffened by epoxy resin laminated glass fabric and epoxy resin liquid joinery and structural bondings. this building system is definitely suited to be realized by home builders or small boatyards, with a basic level of wood craftmanship , in a decent amount of time given the size of the boat., in my view this will allow a small boatyard to build and offer a highly customized top level sailboat keeping the final prize to a reasonable level, which is basically the main concern when it comes to manage a small boatyard..

Everyone who digs boating has heard of the Hobie Cat, the sleek little catamaran that burst on the scene and captured the attention of all the fast-action sailors.
Marked by asymmetrical hulls and special trampoline supports, the Hobie can reach speeds above 20 mph and perform with a rare agility.
But it has one drawback.
It costs mucho dinero.
Thus, we introduce the Hobby Kat, sailboat plans, a build-it-yourself version of the “Hobie” that should cost from half to a third of the commercial version. If you have the moola, of course, go for a Hobie and have the time of your life on the water.
If not, try our Hobby
The homebuilt is not quite the same.
But she sails sweetly and fast—qualities which have made the “Hobie” popular
Even in a light air she’ll slip through the water at a fast clip.
She has no centreboards, leeboards or keel, and needs none.
The inside of each hull has built-in lift, like an airplane wing, so that as the boat heels and one hull digs in the boat is pulled back to windward.

She can run in very shallow water and the rudders kick up for beaching.
You can carry her on a trailer or even disassemble her.
Many a “stink pot” addict will take a second look at Tern because she planes in modest breezes, is easy to handle, and her streamlined prow arid pod-shaped, “inland scow” type hull offer slight water resistance. Then too, there’s a charm about the tiller of a sailer that’s not matched by the wheel of a motor-powered boat. Part of it is the challenge of making the most of nature’s free-wheeling breezes. Even with her 72sq.ft of sail, this Free Sailboat Plan is remarkably stable, and packs as many as four persons aboard
For thousands of inland lakes, Tern is the answer to sailing water sport, she is rugged and easy to launch
And she’s remarkably easy to build.
Falcon is a small, speedy, sporty sailboat which handles well. Tests on the original Falcon showed that she could easily out-distance boats of comparable size such as the one design class Snipe and Comet sailers.
And she will pace neck and neck with 18 footers with considerably greater sail spread.
This strong, beamy, eight-foot pram may be sailed either cat-rigged or sloop-rigged.
The dagger-board may be adjusted forward to balance the helm when sailing with the addition of a jib sail.
Oars or a small outboard motor may also be used to power this versatile Free Sailboat Plans.
Dart” is a small two or three person sailing craft, designed for use on protected waters such as bays. lakes, rivers or wherever sheltered waters are found. Its construction will repay the builder handsomely and provide a fast sailing craft, light in weight, easily transportable and cheap to construct with all difficult joinery eliminated
It provides thrilling and economical sport.
The 'Crescent', designed by C. T. Allen, is the ideal sailboat for day sailing on a small lake, river, or protected waters of a bay.
Centreboard design (Fig. 2) reduces Crescent's draft, so Shallow is not a problem.
Its broad beam of over 5½ft. makes it an ideal family boat because there is room for a cockpit large enough to accommodate four adults or two adults and three kids, and side and forward decks big enough to stretch out on when sun bathing.
"Jewel" is a 16' Crescent Sailboat being built by Mike Allen from the free sailboat plans by C.T .Allen in the 1958 "Boat Builders Handbook". And what a superb job Mike is doing check out his photos here .

Sailing enthusiasts and backyard boat builders are not likely to find free boat plans for a sailing pram that can be built faster, lighter, stronger, or less expensively than Graefin-10. Two men can begin work on a Friday evening and have a smart, lively 10-ft. 85-pound sailboat in the water by Sunday evening (it’s been done).
Zephyr Is a refinement of a type of boat developed by the English for use in the rough open waters of the English Channel. Not only is it fast under sail, but it can stand up under punishment. And it’s light enough to be easily loaded atop an auto or light trailer.
Skimming off a brisk wind or with the wind abeam, Breeze-Baby actually planes with one person aboard. Despite her rowboat lines that make her easy to build, she handles easily under her simple sail, an ideal first boat. Simple lines are adapted to plywood construction that’s strong, light and that keeps Breeze-Baby’s bilges dry
You can take her with you atop your car or on a lightweight trailer for summer fun wherever you vacation or get in a week-end’s sailing.
Cat’s Paw is easy to build because of the straight-sided hulls. The sheer line is flat and that simplifies building the form. Bow and stern are straight, so there’s no cockeyed bevel to fit and fuss with
She Is an Ideal boat to learn or practice sailing in because she will forgive so many mistakes.

Yacht design.
We provide stock boat plans for both monohull and multihull sailing vessels, including sailing skiffs and sharpies. Our designs mainly feature timber construction, in plywood or cedar strip plank composite construction, using the W.E.S.T. system (wood epoxy saturation technique). Our designs are intended mainly as cruising boats, although several have done well in racing. All designs are suitable for amateur boat builders.

It wasn’t so long ago that 30- to 35-foot cruising sailboats were likely to be the largest yachts found in many a harbor. And while 40-something and even 50-something footers are all the rage at boat shows today, there’s a lot to be said for setting sail on a boat big enough to carry family and friends, but still small enough to be easily maintained and handled alone from time to time. Small cruising sailboats are simple to dock or tie up to a mooring, and finding long-term marina space is easier as well.
Choosing a cruising sailboat, no matter the size, is a big decision. And it helps to have a trusted list of boats to get started. Here, then, is a look at 10 of the best daysailers , weekenders and coastal cruising sailboats under 35 feet that are all in production and can be purchased new.
A quarter-century ago, Garry Hoyt launched what would come to be known as the daysailer genre with the introduction of the Alerion Express 28, a boat designed by the late Carl Schumacher that featured a minimal interior and a large cockpit where an owner and guests could enjoy the simple joy of sailing. Traditional and lovely looking—but with a quite modern underbody and a powerful sail plan—Hoyt, ever the marketer, proclaimed the boat to be “the prettiest girl at the dance.”
Since then, a number of siblings ranging from 20 to 41 feet have been added to the Alerion family, including the Alerion Sport 30, which retains the graceful sheer line, oval ports and stylish overhangs of the original Schumacher design. Yet with input from naval architect Langan Design Partners, it also embraces a solid measure of performance-oriented DNA.

In every Boat of the Year contest, it seems, a boat rises up after sea trials to make a lasting impression on the judges. For 2018, that boat was the Bavaria Cruiser 34.
Says Boat of the Year Judge Tim Murphy, “The Bavaria was a lovely boat to sail. It has a single rudder, and she answered her helm just beautifully in the conditions we had today. We started off with around 10 knots of breeze that built to 13 to 15 knots. As a sailboat, it was just a pleasurable sailing experience, among the best we had during our judging. It was among the boats that felt like a really happy sailing experience.

Sailed as part of the 2020 Boat of the Year sea trials, the 31-foot-3-inch Beneteau Oceanis 30.1 was the compact yacht best-equipped and spec’d out as a dedicated cruising boat, and not coincidentally, it was also awarded the title of Best Performance Cruiser for 2020. But don’t let her cozy interior accommodations fool you; this is also one peppy little vessel.

The 2017 Boat of the Year (BOTY) contest featured a stellar crop of crossover cruiser/racers; however, when all the testing was said and done, our independent panel of judges was sold on the Dehler 34, naming it the year’s Best Performance Cruiser. Designed by the highly regarded Judel/Vrolijk naval-architecture consortium, whose reputation was fostered by longtime success in international yacht-racing circles, the 34-footer combined contemporary good looks and a sweet turn of speed with better-than-average comfort and accommodations below. It didn’t hurt that the boat, nicely equipped at $215,000, was the least-expensive entry in the entire 2017 fleet. All in all, it proved to be a winning formula.

Dufour Yachts introduced its new 360 Grand Large model to CW’s Boat of the Year team in 2018 as a coastal cruiser intended for a couple or perhaps a small family. With that in mind, judge Alvah Simon found numerous clever elements to praise within the boat’s 35-foot-2-inch hull—a relatively modest LOA compared to the many 40-, 50- and 60-footers on display at the U.S. Sailboat show in Annapolis, Maryland.

After a roughly 10-year hiatus from the U.S. marketplace, the Slovenian builder Elan is back in a big way. For the 2017 Boat of the Year contest, the company launched a pair of new boats in the States, including the Elan E4, a 34-foot-9-inch performance cruiser with an emphasis on performing, designed by renowned British naval architect Rob Humphreys. The brand has been in business for seven decades and lately is perhaps even better known in America for its skis. Not surprisingly, given its complementary product lines—lots of sailors are fine skiers—its boats are as sleek and sporty as its boards.

Way back in the 1970s, when the well-known Italian boatyard Grand Soleil was just getting started, its first model was a Finot-designed 34-footer. With over 300 units sold, it was an instant success, and launched the company on an upward trajectory that spanned the intervening decades, mostly with an ongoing series of much larger, more complex racer/cruisers. For 2020, the builder decided to return to its roots with a completely revamped Grand Soleil 34, and it’s a terrific boat.

Value. How does one determine it? Price is most certainly a factor. In the case of new boats, and our Boat of the Year competition, it means something more. As sailors, we wish to recognize good boats that not only are affordable but offer other, tangible rewards. The ability to get couples and families out on the water, to have a weekend escape, to take them on coastal vacations and even maybe a sabbatical to the islands, all without breaking the bank. For 2019, the judging panel determined that one boat had the potential to do these things better than the rest, which is why they awarded the Best Value prize to the Hanse 348.
With a price tag under $200,000, during sea trials the Hanse 348 wowed the judging team from the get-go. “In only about 8 knots of breeze, we were seeing 5.7 knots upwind and pointing very nicely, and even registered 6.5 knots once we cracked off,” said Tim Murphy. “It’s a pretty sweet little boat.”

Of the performance cruisers that made their North American debut in 2020, in terms of sheer appearance, the futuristic 34-foot Italia 9.98 was easily the most distinctive. There are actually two versions of the boat: the 34 Club—which is the cruising alternative, the primary features of which are its twin wheels—and the 34 Fuoriserie—the racing model, and the one we tested, with its tiller steering being the identifying characteristic.

Beginning with the popular little J/24 way back in 1977, J/Boats has become famous for its steady introduction of terrific racing and cruising boats, almost all of which shared one main characteristic: They sailed like a witch. More than four decades later, having built more than 50 separate, mind-boggling models, the Johnstone family that designs, markets and sells the brand shows no signs of slowing down. Their latest offering, for 2020, was another fast and fun racer/cruiser: the 32-foot-7-inch J/99.
