www.yachtsurvey.com There are over 180 articles on buying, owning and maintaining boats and yachts, written by myself based on experience in surveying over 5000 boats of all types. MARINE ENGINES : GAS ENGINES There are two primary reasons for this: (1) better cooling system design, and (2) better gaskets. One engine marinizer has had gasket and cooling system problems for going on two decades now and still displays no willingness to resolve the problem. Frankly, there's no excuse for a line of engines in which the head gaskets go bad in 4-6years
SURVEYING WOOD HULLS Online article for marine surveyors by David Pascoe, marine surveyor, NAMS-CMS. Let start with the point that most independent surveyors I know are no longer in the business of performing prepurchase surveys on wooden boats and the reason is simple. Surveyors have learned the hard way that surveying wood boats is very difficult and fraught withrisks.
MARINE ENGINES : DRIVE SYSTEM ALIGNMENT BY DAVID PASCOE The Nature of Inboard Drive Systems It is a common belief that engines and shaft couplings have to be aligned to tolerances of a few thousandths.There is some misunderstanding about this. Yes, the shaft coupling to transmission coupling needs to fit within several thousandths, but what were talking here is the coupling fit, not theshaft alignment.
BOAT HULLS - CORES AND STRUCTURAL ISSUES: ONLINE ARTICLES The roots of fiberglass boat building go all the way back to the 1930's when, so far as I know, the first reinforced plastic boat was built by Gar Wood in 1936. Were it not for the Depression and W.W.II, production fiberglass boat building probably would have been initiated in the 1940's but, as it was, really began in earnest in 1960 with the MAINTENANCE AND TROUBLESHOOTING : MAINTAINING STERN DRIVES Anyone who has owned a stern drive boat or two knows how troublesome and costly stern drives can be.A typical drive replacement runs $2,500 or more, and with a twin engine boat you've got more than $5,000 worth of machinery hanging off the back of the boat. Take a tour of a few boat yards and you are likely to see dozens of boats with their drives removed, many because they are corrosion damaged.CORED HULL BOTTOMS
Cored hull bottom failures are starting to show up in increasing numbers, just as I had predicted. After all, the industry went though this ridiculous situation in the 1960's, again in the early 1980's and now in the decade of single digits. The industry love affair with cored bottoms seems to run in twenty year cycles and here we areagain.
SEA RAY AND BALSA CORE BOTTOMS The debate over the use of balsa cores in boat bottoms seems recently to have come to an end when, in October, 2002, Powerboat Reports ran a piece entitled Core Complaints. Purporting to be an editorial, when in fact the piece ran five pages and is a full-blown article, including a response from Sea Ray to a PBR inquiry for Sea Ray's response to allegations of serious problems with the use of MOISTURE METERS ON BOAT HULLS by David Pascoe, marine surveyor. Do they produce reliable results? Numerous boat buyers ask this question. Their surveyors used a moisture meter on the hull and gave them the results of the meter readings, but were apparently unwilling or unable to provide a comprehensive explanation ofDOCKING IN STYLE

BOAT REVIEWS BY DAVID PASCOE, MARINE SURVEYOR David Pascoe is a second generation marine surveyor in his family who began his surveying career at age 16 as an apprentice in 1965 as the era of wooden boats was drawing to a close. Certified by the National Association of Marine Surveyors in 1972, he has conducted over 5,000 pre purchase surveys in addition to having conducted hundreds of MARINE ENGINES : ENGINE-SHAFT ALIGNMNET When it comes to yacht maintenance, one of the least understood and most overlooked systems that require maintenance, engine and shaft alignment probably heads the list. Here's a short list of the problems associated with incorrect alignment and poor or worn out enginemounts:
PURSUIT 3000 OFFSHORE Definitely a dedicated fisherman, the Pursuit 3000 has much to offer the serious angler, starting with a twelve foot beam on a 31 footer and an extra large cockpit. Pursuit makes some boats that they call "express fisherman" but this one won't leave you with any illusionsabout it

The Detroit injector system is just one of the major differences over four cycle engines. Credit: Detroit Diesel Allison. The two stroke cycle. The push rods of these engines are also about 33% longer than most 4 stroke engines, creating more rotational mass and therefore more rotational torque.DOCKING IN STYLE

In this essay I will attempt to dispel some of the myths, and give a brief discussion of the basis by which one should consider the pros and consof each choice.
MAKO 221 - BOAT REVIEW BY DAVID PASCOE, MARINE SURVEYOR Better for lakes and bays. This is the kind of boat you can put on a trailer and store in the side yard darn near forever without having the thing crumble before your eyes. No frills, tough, utilitarian, easy to keep up because there's not much too it, and not much to go wrong. No upholstery, no teak, no wood, no aluminum, no die cast zincalloy.
ALBEMARLE 305: BOAT REVIEW BY DAVID PASCOE, MARINE SURVEYOR 14,900 lbs. Top Speed. 30 knots. Everybody's been asking about them. We've gotten hundreds of requests for reviews on Albemarle boats, the only problem being that we hadn't surveyed one. That state of affairs recently changed when this 1997 model 305 came out way. Fully loaded and with a tower, this one is powered with 300 HP Caterpillar 3116 SEA RAY SUNDANCER 290 UPDATE It's not often that we get the chance to see two of the same model boat nearly back-to-back, but in this case we did.

This hull shape, as shallow as it is, unquestionably is a fair weather sailor. The depth between water line and keel at the stern is only 18", amazing for a 39 foot boat. Out on the stream with three footers rolling, she comes to a grinding halt unless you want to bash her topieces.

The one serious drawback of this boat is the narrow beam at waterline. The super wide beam at deck level gives the appearance of a lot of interior space, but you find your feet have a lot less room than your head. The central companionway is slightly angled and a bit cramped, as are both staterooms.ISLAND GYPSY 40

The style of the boat is a flying bridge sedan, but it is built on a modified trawler style hull. Defining my terms for you trawler afficiandos, "trawler style" meansthat

In my view, its just plain dangerous. Even if you can make the cockpit 100% water tight, remember that water is very heavy. It weights 64 lbs per cubic foot. And when you end up with a thousand pounds or more of water back there, all that light-weight plastic may not hold togetherso well.

HATTERAS YACHTS INTRODUCTION by David Pascoe. A long with Bertram and Hinckley, Hatteras has the distinction of being one of the first three production fiberglass boat builders to start up in around 1960. Oddly enough all three survive today, although Bertram may yet go by the wayside.PURSUIT 2855
Overall, this is a decent quality boat, but it's not as good as it should be. The work of the bean counters and profit stretchers is clearly apparent. Structurally she outpaces most in her class, but when it comes to fitting out, she's an also-ran. Even so, she's got a lot to recommend her in the way of practical design and overalldurability.
BOAT CARVER 370
Now, when a builder enters the larger boat market, particularly with boats priced well over 1/4 million, that attracts our interest. Not because we're interested in the higher rollers, but to see what a builder can get away with in this price range. (Sort of like wondering if you could sell a Rolls Royce with plastic bumpers.) And also when the literature is peppered with words like quality PURSUIT 3000 OFFSHORE Definitely a dedicated fisherman, the Pursuit 3000 has much to offer the serious angler, starting with a twelve foot beam on a 31 footer and an extra large cockpit. Pursuit makes some boats that they call "express fisherman" but this one won't leave you with any illusionsabout it
BLACKFIN 33
This gives it an incredible 26 degree dead rise with a very fine entry that was the smoothest riding boat I've been on in years. Even the later model Blackfins won't run with this aged model. In a very short, two-foot, tide rip chop, honking along at 28 knots we hardly evennoticed the chop.
BERTRAM 30 EXPRESS
Finally! Here's a boat that we've been looking to review for years now. The reason we haven't is because it's a rarity, in production for only three years, and only several hundred built. We last ran into one about 6 years ago and was immediately impressed with it. And haven't seen another one since. Boo. MARINE ENGINES : GAS ENGINES There are two primary reasons for this: (1) better cooling system design, and (2) better gaskets. One engine marinizer has had gasket and cooling system problems for going on two decades now and still displays no willingness to resolve the problem. Frankly, there's no excuse for a line of engines in which the head gaskets go bad in 4-6years
BUYING A BOAT OR YACHT : WHAT YOU SHOULD KNOW ABOUT BUYING If you are a longtime boat owner, you know that owning a boat is a costly affair. Making decisions that keep not only the cost of your initial purchase, but also the long-term cost of ownership, well within you financial means is one of the critical factors of keeping the pleasure in boating. Its very hard to enjoy your boat when it becomes an unexpected drain on your financial resources.

There are few problems that can cause more damage and detract from the value of your boat than window, porthole and hatch leaks. Even well constructed boats will eventually develop leaks simply because boats are not totally rigid structures. In fact, they twist and flex quite a bit, and poorly constructed boats flex a lot, which is why we see so many entry-level boats that more or less just MAINTENANCE AND TROUBLESHOOTING : MAINTAINING STERN DRIVES Anyone who has owned a stern drive boat or two knows how troublesome and costly stern drives can be.A typical drive replacement runs $2,500 or more, and with a twin engine boat you've got more than $5,000 worth of machinery hanging off the back of the boat. Take a tour of a few boat yards and you are likely to see dozens of boats with their drives removed, many because they are corrosion damaged. DIESEL ENGINES: ALUMINUM COOLING SYSTEM COMPONENT FAILURES Bottom line: The effort to make diesel engines lighter by using aluminum components for the cooling system isn't going to work. And, of course, these parts didn't finally fail until the engine was long out of warranty, so the boat owner had to foot the bill. Fortunately, there is a better way to reduce the weight of cast iron tanks. HULL BLISTERS ON BOATS AND YACHTS The 8 Grand Conundrum. People with boats undergoing blister repairs often write us to say, "My boat has been drying out for six months now, and it still will not dry. The moisture meter readings are still as high as ever." The usual procedure is to just let the boat sit and "dry out" naturally by a process of evaporation.EXHAUST RISERS
All marine inboard engines have exhaust risers. The exhaust riser has two functions: (1)to keep water from backing up into the engine through the exhaust piping and, (2) it serves as the device that introduces cooling water into the exhaust exit piping system. If the riser fails to accomplish either of those jobs successfully, the end result is the arrival of Uncle Big Bill on the scene.CORED HULL BOTTOMS

MARINE ENGINES : DRIVE SYSTEM ALIGNMENT BY DAVID PASCOE The Nature of Inboard Drive Systems It is a common belief that engines and shaft couplings have to be aligned to tolerances of a few thousandths.There is some misunderstanding about this. Yes, the shaft coupling to transmission coupling needs to fit within several thousandths, but what were talking here is the coupling fit, not theshaft alignment.

MARINE ENGINES : POWER OPTIONS Yes, gas engines do pose a carbon monoxide hazard, but most of this hazard comes from gas generators. Diesels are safer from the standpoint of explosions as diesel oil vapors are not explosive. Prior to the advent of water cooled turbochargers, statistics show that fires caused by diesel engines ran nearly 5 times the rate over gasengines.
MARINE SURVEYING : HULL DESIGN DEFECTS Online article on hull design defects by David Pascoe, marine surveyor, NAMS-CMS. Anyone who has ever seen airframe construction, particularly jet aircraft, understands why aircraft can be built with skins that are extremely thin. And while an aircraft isn't subjected to the same type of forces as a boat hull, the fuselage is the hull and must be strong in different ways.DOCKING IN STYLE
The unfortunate thing about docking in crowded marinas is probably less a matter of the embarrassment of hitting some one else's boat, but that there are usually so many people around to see you do it! We've all screwed up one time or another, so we know how embarrassing it is to be standing there, half panic-stricken at the controls of our boat (which is out of control) while a half dozen of46 POST CONVERTIBLE
The one serious drawback of this boat is the narrow beam at waterline. The super wide beam at deck level gives the appearance of a lot of interior space, but you find your feet have a lot less room than your head. The central companionway is slightly angled and a bit cramped, as are both staterooms.ISLAND GYPSY 40
by David Pascoe. This the first mainland China import we've reviewed, built by Jiang Hua in She Kau, PRC and imported by Kong & Halvorsen under the Island Gypsy trade name. The style of the boat is a flying bridge sedan, but it is built on a modified trawler style hull. Defining my terms for you trawler afficiandos, "trawler style" meansthat

Now, when a builder enters the larger boat market, particularly with boats priced well over 1/4 million, that attracts our interest. Not because we're interested in the higher rollers, but to see what a builder can get away with in this price range. (Sort of like wondering if you could sell a Rolls Royce with plastic bumpers.) And also when the literature is peppered with words like quality BUYING A BOAT OR YACHT : WHAT YOU SHOULD KNOW ABOUT BUYING If you are a longtime boat owner, you know that owning a boat is a costly affair. Making decisions that keep not only the cost of your initial purchase, but also the long-term cost of ownership, well within you financial means is one of the critical factors of keeping the pleasure in boating. Its very hard to enjoy your boat when it becomes an unexpected drain on your financial resources. MARINE ENGINES : GAS ENGINES There are two primary reasons for this: (1) better cooling system design, and (2) better gaskets. One engine marinizer has had gasket and cooling system problems for going on two decades now and still displays no willingness to resolve the problem. Frankly, there's no excuse for a line of engines in which the head gaskets go bad in 4-6years
BOAT HULLS - CORES AND STRUCTURAL ISSUES: ONLINE ARTICLESBOAT STRUCTURE DESIGNBOAT STRUCTURE DRAWINGS The roots of fiberglass boat building go all the way back to the 1930's when, so far as I know, the first reinforced plastic boat was built by Gar Wood in 1936. Were it not for the Depression and W.W.II, production fiberglass boat building probably would have been initiated in the 1940's but, as it was, really began in earnest in 1960 with theBOAT WINDOWS
There are few problems that can cause more damage and detract from the value of your boat than window, porthole and hatch leaks. Even well constructed boats will eventually develop leaks simply because boats are not totally rigid structures. In fact, they twist and flex quite a bit, and poorly constructed boats flex a lot, which is why we see so many entry-level boats that more or less just MAINTENANCE AND TROUBLESHOOTING : MAINTAINING STERN DRIVES Anyone who has owned a stern drive boat or two knows how troublesome and costly stern drives can be.A typical drive replacement runs $2,500 or more, and with a twin engine boat you've got more than $5,000 worth of machinery hanging off the back of the boat. Take a tour of a few boat yards and you are likely to see dozens of boats with their drives removed, many because they are corrosion damaged. DIESEL ENGINES: ALUMINUM COOLING SYSTEM COMPONENT FAILURES Bottom line: The effort to make diesel engines lighter by using aluminum components for the cooling system isn't going to work. And, of course, these parts didn't finally fail until the engine was long out of warranty, so the boat owner had to foot the bill. Fortunately, there is a better way to reduce the weight of cast iron tanks. HULL BLISTERS ON BOATS AND YACHTS The 8 Grand Conundrum. People with boats undergoing blister repairs often write us to say, "My boat has been drying out for six months now, and it still will not dry. The moisture meter readings are still as high as ever." The usual procedure is to just let the boat sit and "dry out" naturally by a process of evaporation.EXHAUST RISERS
All marine inboard engines have exhaust risers. The exhaust riser has two functions: (1)to keep water from backing up into the engine through the exhaust piping and, (2) it serves as the device that introduces cooling water into the exhaust exit piping system. If the riser fails to accomplish either of those jobs successfully, the end result is the arrival of Uncle Big Bill on the scene.CORED HULL BOTTOMS
Cored hull bottom failures are starting to show up in increasing numbers, just as I had predicted. After all, the industry went though this ridiculous situation in the 1960's, again in the early 1980's and now in the decade of single digits. The industry love affair with cored bottoms seems to run in twenty year cycles and here we areagain.
SEA RAY AND BALSA CORE BOTTOMS The debate over the use of balsa cores in boat bottoms seems recently to have come to an end when, in October, 2002, Powerboat Reports ran a piece entitled Core Complaints. Purporting to be an editorial, when in fact the piece ran five pages and is a full-blown article, including a response from Sea Ray to a PBR inquiry for Sea Ray's response to allegations of serious problems with the use of BUYING A BOAT OR YACHT : WHAT YOU SHOULD KNOW ABOUT BUYING If you are a longtime boat owner, you know that owning a boat is a costly affair.

MARINE ENGINES : DRIVE SYSTEM ALIGNMENT BY DAVID PASCOE The Nature of Inboard Drive Systems It is a common belief that engines and shaft couplings have to be aligned to tolerances of a few thousandths.There is some misunderstanding about this. Yes, the shaft coupling to transmission coupling needs to fit within several thousandths, but what were talking here is the coupling fit, not theshaft alignment.

MARINE ENGINES : POWER OPTIONS Yes, gas engines do pose a carbon monoxide hazard, but most of this hazard comes from gas generators. Diesels are safer from the standpoint of explosions as diesel oil vapors are not explosive. Prior to the advent of water cooled turbochargers, statistics show that fires caused by diesel engines ran nearly 5 times the rate over gasengines.
MARINE SURVEYING : HULL DESIGN DEFECTS Online article on hull design defects by David Pascoe, marine surveyor, NAMS-CMS. Anyone who has ever seen airframe construction, particularly jet aircraft, understands why aircraft can be built with skins that are extremely thin. And while an aircraft isn't subjected to the same type of forces as a boat hull, the fuselage is the hull and must be strong in different ways.DOCKING IN STYLE
