The first project for Pacific Boats was the Olson 30, which was put into production in 1978. Over 200 of these 3600-pound ULDBs were sold, and the builder claims they have gathered in sufficient numbers to support one-design racing in Seattle, the Great Lakes, Annapolis, Texas, and Long Island Sound, as well as several spots in California. Pacific Boats was a small firm that built only the Olson 30 and the Olson 40, both to quality standards.
Some people wonder how the ULDB can be built so light and still be seaworthy offshore. The answer lies in the fact that a light boat is subjected to much lighter loads than a heavy boat when pounding through a sea (there is tremendous saving in weight with a stripped-out interior). And perhaps more importantly, ULDB builders have construction standards that are well above average for production sailboats. The ULDB builders say that their close proximity to each other in Santa Cruz, combined with their open sharing of technology, has enabled them to achieve these high standards. The Olson 30 is no exception. The hull and deck are fiberglass, vacuumbagged over a balsa core. The process of vacuum-bagging insures maximum saturation of the laminate and core with a minimum of resin, making the hull light and stiff. The builder claims that -they have so refined the construction of the Olson 30 that each finished hull weighs within 10 pounds of the standard. The deck of the Olson does not have plywood inserts in place of the balsa where winches are mounted, instead relying on external backing plates for strength.
The hull to deck joint is an inward turned, overlapping flange, glued with a rigid compound called Reid’s adhesive, and mechanically fastened with closely spaced bolts through a slotted aluminum toerail. This provides a strong, protected joint, seaworthy-enough for sailing offshore. The aluminum toerail provides a convenient location for outboard sheet leads, but is painful for those sitting on the rail.
The Olson 30’s 1800-pound keel is deep (5′ 1″ draft) and less than five inches thick. Narrow, bolted-on keels need extra athwartship support. The Olson 30 accomplishes this with nine six-inch bolts, and one ten-inch bolt (to which the lifting eye is attached). The lead keel is faired·with polyester putty and then completely wrapped with fiberglass to seal the putty from the marine environment.
Too many builders neglect sealing autobody putty-faired keels, and too many boat owners then find the putty peeling off at a later date. The Olson’s finished keel is painted, and, on the boats we’ve seen, remarkably fair. The keel-stepped, single-spreader, tapered mast is cleanly rigged with 5/32-inch Navtec rod rigging and internal tangs. The mast section is large enough for peace of mind in heavy air. The halyards exit the mast at well-spaced intervals, to avoid creating a weak spot. The chainplates are securely attached to half-bulkheads of I-inch plywood. In addition, a tie-rod attaches the deck to the mast, tensioned by a turnbuckle. While this arrangement should provide adequate strength, we would prefer both a tie-rod and a full bulkhead that spans the width of the cabin to absorb the compressive loads that rig tension puts on the deck.
The rudder’s construction is labor-intensive but strong. Urethane foam is hand shaped to templates, then glued to a two-inch diameter solid fiberglass rudder post. The builder prefers fiberglass because it has more “memory” than aluminum or steel. Stainless steel straps are wrapped around the rudder and mechanically fastened to the post. Then the whole rudder assembly is faired, fiberglassed, and painted.
Handling Under Sail
For those of you who agonize over whether your PHRF rating is fair, consider the ratings of ULDBs. The Santa Cruz 50 rates 0; that’s right, zero. The 67-foot Merlin has rated as low as minus 60. The Olson 30 rates anywhere from 90 to 114, depending on the local handicapper. Olson 30 owners tell us that the boat will sail to a PHRF rating of 96, but she will almost never sail to her astronomical lOR rating of 32 (the lOR heavily penalizes ULDBs). ULDBs are fast. They are apt to be on the tender side, and sail with a quick, “jerky” motion through waves. Instead of punching through waves, they ride over them. Owners tell us that they do far less cruising and far more racing than they had expected to do when they bought the boat. They say it’s more fun to race because the boat is so lively.
Like most ULDBs, the Olson 30 races best at the extremes of wind conditions-under 10 knots and over 20 knots. Although her masthead rig may appear short, it is more than powerful enough for her displacement. Owners tell us that she accelerates so quickly you can almost tack at will – a real tactical advantage in light air. In winds under 10 knots, they say she sails above her PHRF rating, both upwind and downwind. In moderate breezes it’s a different story. Once the wind gets much above 10 knots, it’s time to change down to the #2 genoa. In 15 knots, especially if the seas are choppy, it’s very difficult for the Olson 30 to save her time on boats of conventional displacement, according to three-time national champ Kevin Connally. The Olson 30 is always faster downwind, but even with a crew of 5 or 6, she just can’t hang in there upwind. In winds above 20 knots, the Olson 30 still has her problems upwind. But when she turns the weather mark the magic begins. As soon as she has enough wind to surf or plane, the Olson 30 can make up for all she looses upwind, and more. The builder claims that she has pegged speedometers at 25 knots in the big swells and strong westerlies off the coast of California. That is, of course, if the crew can keep her 1800-pound keel under her 761-square foot spinnaker. The key to competitiveness in a strong breeze is the ability of the crew. Top crews say that because she is so quick to respond, they have fewer problems handling her in heavy air. However, an inexperienced crew which cannot react quickly enough, can have big problems. “The handicappers say she can fly downwind, so they give us a low (PHRF) rating. But they don’t understand that we have sail slow, just to stay in control,” complained the crew of one new owner.
Like any higher performance class of sailboat, the Olson 30 attracts competent sailors. Hence, the boat is pushed to a higher level of overall performance, and the PHRF rating reflects this. An inexperienced sailor must realize that he may have a tougher time making her sail to this inflated rating than a boat that is less “hot.”
The two most common mistakes that new Olson 30 owners make are pinching upwind and allowing the boat to heel excessively. ULDBs cannot be sailed at the 30 degrees of heel to which many sailors of conventional boats are accustomed. To keep her flat, you must be quick to shorten sail, move the sheet leads outboard, and get more crew weight on the rail. You can’t afford to have a person sitting to leeward trimming the genoa in a 12-knot breeze. To keep her thin keel from stalling upwind, owners tell us it’s important to keep the sheets eased and the boat footing.
Being masthead-rigged, the Olson 30 needs a larger sail inventory than a fractionally rigged boat. Class rules allow one mainsail, six headsails (jibs and spinnakers) and a 75-percent storm jib. Owners who do mostly handicap racing tell us they often carry more than six headsails.
Handling Under Power
Only a few of the Olson 30s sold were equipped with inboard power. This is because the extra weight of the inboard and the drag of the propeller, strut and shaft are a real disadvantage when racing against the majority of Olson 30s, which are equipped with outboard motors. The Olson 30 is just barely light enough to be pushed by a four to five horsepower outboard. It takes a 7.5 horse outboard to push the Olson 30 at 6.5 knots in a flat calm. The Olson’s raked transom requires an extra long outboard bracket, which puts the engine throttle and shift out of reach for anyone much less than 6 feet tall: “A real pain,” said one owner. Storage is a problem, too. Even if you could get the outboard through the stern lazarette’s small hatch, you wouldn’t want to race with the extra weight so far aft. As a result, most owners end up storing the outboard on the cabin sole. The inboard was an optional, 154-pound, 7-horsepower, BMW diesel. Unlike most boats, the Olson 30 will probably never return the investment in an inboard when the boat is sold. It detracts from the boat’s primary purpose-racing.
Without an inboard, owners have a problem charging the battery. Owners who race with extensive electronics have to take the battery ashore after every race for recharging. If the Olson 30 weren’t such a joy to sail in light air, and so maneuverable in tight places, the lack of inboard power would be a serious enough drawback to turn away more sailors than it does.
In most respects, the Olson 30 is a good sea boat. Although the cockpit is 6-1/2 feet long, the wide seats and narrow floor result in a relatively small cockpit volume, so little sea water can collect in the cockpit if the boat is pooped or knocked down. However, foot room is restricted, while the width of the seats makes it awkward to brace your legs on the leeward seat. The seats themselves
There are gutters to drain water off the leeward seat. The long mainsheet traveler is mounted across the cockpit. The Olson 30’s single companionway dropboard is latchable from inside the cabin, a real necessity in a storm offshore. A man-overboard pole tube in the stern is standard equipment. Teak toerails on the cockpit combing and on the forward part of the cabin house provide good footing, and there are handholds on the after part of the cabin house. The tapered aluminum stanchions are set into sockets molded into the deck and glassed to the inside of the hull, a strong, clean, leak-proof system. However, the stanchions are not glued or mechanically fastened into the sockets. If pulled upwards with great force they can be pulled out. We feel this is a safety hazard. Tight lifelines would help prevent this from happening, but most racing crews tend to leave them slightly loose so they can lean further outboard when hanging over the rail upwind. If the stanchions were fastened into the sockets with bolts or screws they would undoubtedly leak. A leakproof solution to this problem should be devised and made available to Olson 30 owners. The cockpit has two drains of adequate diameter. The bilge pump, a Guzzler 500, is mounted in the cockpit. As is common on most boats, the stern lazarette is not sealed off from the rest of the interior. If the boat were pooped or knocked down with the lazarette open, water could rush below through the lazarette relatively unrestricted. As the Olson 30 has a shallow sump, there is little place for water to go except above the cabin sole. A “paint-roller” type non-skid is molded into the Olson 30’s deck It provides excellent traction, but it is more difficult to keep clean than conventional patterned non-skid.
The Olson 30 is well laid out with hardware of reasonable, but not exceptional, quality. All halyards and pole controls lead to the cockpit through Easylock 1 clutch stoppers. The Easylocks are barely big enough to hold the halyards; they slip an inch under heavy loads. Older Olsons were equipped with Howard Rope Clutches. The Howards had’ a history of breaking (although the manufacturer has now corrected the problem). The primary winches, Barient 22s, are also barely adequate. Some owners we talked to had replaced them with more powerful models. Schaefer headsail track cars are standard equipment. One owner complained that he had to replace them with Merrimans because the Schaefers kept slipping.
Leading the vang to either rail and leading the reefing lines aft is also recommended. The mast partner is snug, leaving no space for mast blocks. The mast step is movable to adjust the prebend of the spar. The partner has a lip, over which a neoprene collar fits. The collar is hose-clamped to the mast. This should make a watertight mast boot. However, on the boat we sailed, the bail to which the boom vang attached obstructed the collar, causing water to collect and drain into the cabin.
The yolked backstay is adjustable from either quarter of the stem, one side being a 2:1 gross adjustment and the other side being an 8:1 fine tune. A Headfoil II is standard equipment. There is a babystay led to a track with a 6:1purchase for easy adjustment. The track is tied to the thin plywood of the forward V -berth with a wire and a turnbuckle. On the boat we sailed, the padeye to which the babystay tie rod is attached was seen to be tearing out from the V-berth.
There is a port in the deck directly over the lifting eye in the bilge. This makes for quick and easy drysailing. The Olson 30, however, is not easily trailered; her 3600 pounds is too much for all but the largest cars, and her 9.3-foot beam requires a special trailering permit.
The Olson 30 is cramped belowdecks. Her low deckhouse and substantial sheer may make her one of the sexiest-looking production boats on the water, but the price is headroom of only four feet, five inches. There is not even enough headroom for comfortable stooping. Moving about below is a real grind for an average-sized person. To offset the confinement of the interior, the builder has done everything possible to make it light and airy. In addition to the Lexan forward hatch and cabin house windows, the companionway hatch also has a Lexan insert. The inside of the hull is smooth sanded and finished with white gelcoat. There are no full-height bulkheads dividing the cabin. All the furniture is built of lightweight, light-colored, 3/8″ Scandanavian, seven-ply plywood.
The joinerwork is above average and all of the bulkhead and furniture tabbing is extremely neat. There isn’t much to the Olson 30’s interior, but what there is has been done with commendable craftmanship. The cabin sole is narrow, and with the lack of headroom, the woodwork is susceptible to being dinged and scratched from equipment like outboard motors. Once the finish on the wood is broken, it quickly absorbs water, which collects in the shallow bilge. ‘
The Olson 30 is not a comfortable cruiser. Even after you’ve taken all the racing sails ashore, the belowdecks is barely habitable. To save weight the quarterberths are made of thin cushions sewn to vinyl and hung from pipes.These pipe berths are comfortable, but the cushions are not easily removed. Should they get wet it’s likely they would stay wet for some time. Two seabags are hung on sail tracks above the quarter berths, which should help to insure that some clothes stay dry.
Just forward of each quarterberth is a small uncushioned seat locker. Behind each seat is a small portable ice cooler. In one seat locker is the stove, an Origo 3000, which slides up and out of the locker on tracks. The Ongo is a top-of-theline unpressurized alcohol stove, but to operate it the cook must kneel on the cabin sole. To work at the navigation station, which is in front of the starboard seat, you must sit sideways. In front of the port seat is the lavette, with a hand water pump and a removable, shallow, drainless sink. Drainless sinks eliminate the need for a through-hull fitting-a good idea-but they should be deep, not shallow.
Although there are curtains which can be drawn across the V-berth, we think human dignity deserves an enclosed head, especially on a 30’ boat. The V-berth is large and easy to climb into, but there are no shelves above it or a storage locker in the empty bow. In short, if you plan to cruise for more than a weekend, you’d better like roughing it.
A completely equipped Olson 30 ran about $35,000. Today, a used one will cost from $24,000 to $28,000 (note – this was written in 1987, prices are lower in 2015). What do you get for this? You get a boat that’s well built, seaworthy, and reasonably well laid out. You get a boat that, in light air, will sail as fast as boats costing nearly twice as much. Downwind in heavy air, you have a creature that will blow your mind and leave everything (except a bigger ULDB) in your wake. If you spend all of your sailing time racing in a PHRF fleet in an area where light or heavy air dominates, the Olson 30 will probably give you more pleasure for your dollar than almost anything afloat.
However, if you race in moderate air or enjoy more than an occasional short cruise, you are likely to be very disappointed. Before you consider the Olson 30, you must realistically evaluate your abilities as a sailor. There’s nothing worse, after finding out that you can’t race a boat to her potential, than realizing that she is of little use for any other aspect of our sport.
