How to make a 24’ runabout out of two 20’ boats

Words © by Chris (Seabuddy) Brown

This classic 24’ inboard/outboard boat is waiting for a customer to specify a vee-drive shaft drive in the traditional inboard manner. All the other features and desirable traits of a runabout are in place. She runs, rides, and turns like a gem.

The Cherubini 24’ was created by the company using their 20’ boat model. As a family, they have been building boats back to 1937. The current boat company goes back to 1975. Over this time they have worked their magic in many ways. This is an article about one of their magic moments in a long history of inspired boat building.

It looks like they bought the molds and rights to a water jet powered 20’ runabout from an out of business boat builder. They changed that hull to be a stylish, real sweet running I/O boat. Yes, other power is offered from the factory, but all the units seem to use inboard/outboard power.

I now want to drill down to how they created a 24’ boat. They took TWO examples of their sweet running 20’, cut them down the middle (but on an slant) added 4’ in the center, put this all into one boat and blended all of this using their boat building expertise into a 24’ boat. No flat spots, no seams, nothing that does not pass close inspection. I could not do this. Kudos to them.

BTW, they went from a V-6 Mercury Marine GM block powered 20’ boat to a 496 cu. in. displacment, again Chevy GM block, Mercury Marine engine in the 24’. Both boats run much faster than most true classic boats. The 24’ can top 65 MPH with its big block engine.

Has this type of thing been done before? Most say, yes. There are plans and drawings for the classic Donzi 16 and the Donzi 22 models. No drawing or plans for the Donzi 18 boat. The story goes that the 16’s bow and aft sections where cut and two feet were added in the middle to make the Donzi 18.

Cobalt Boats, under 30’

SNAG_Program-0452

Pic shows their 296 Model.

Seabuddy was a dealer years ago for Cobalt Boats with his four retail stores on the west coast.

She has a LOA of 30’ 2” with a permit required for trailering beam of 9’ 5”. Cobalt Boats offers this model in single and twin engine choices. Depending on how one checks off the various choices she sells for about $150,000 new.

All Cobalt boats have their graphics in their gelcoat, a special barrier coat between the gelcoat and the fiberglass layup, Kevlar reinforcement in their hulls, no wood in their structural components, and a unique warranty with special five year engine-drivetrain function coverage among other covered components. Go to their web site and read about their special engine-drivetrain warranty details. You will be impressed.

Boat Trim Tabs: One System’s Ideas

IBEX is an annual marine trade event that provides an opportunity to interact with boat builders and other marine professionals worldwide, to collect immediate feedback, and to form lasting relationships in just three days. IBEX offers marine professionals a single platform to meet the North American marine industry face-to-face about the products that boating and boaters use.

Presented here is one idea that struck Seabuddy as newsworthy for a LinkedIn Pulse listing.

These folks make a system that retro-fit their marine trim tabs to other systems.

Manufacturer’s comment…  “Are you frustrated with your messy hydraulic pump unit? One of the biggest concerns with the hydraulic pump units are their possibility of messy leakage of harmful toxins to the environment. Not to mention the oily mess. But another big concern is the well known slow response of hydraulic units”.

https://www.youtube.com/watch?v=XSQ3bumGE04

This is a good, short video to watch.

More from Lenco…  “The Conversion & Performance Upgrade Kit includes everything necessary to upgrade your current boat without any drilling or filling of holes. You simply discard the hydraulic pump unit and the two Bennett cylinders. Lenco’s new upper mounting brackets fit the existing Bennett mounting holes on the transom. Install the two Lenco electric actuators on your existing Bennett trim blades using the existing lower actuator brackets. Connect our actuator wiring to the existing harness. Jumper wires are included for attaching to current Bennett rocker switch. Complete your trim tab system upgrade with a waterproof Lenco tactile switch or our Auto Glide Boat Leveling System.”

Aston Martin cars getting into the Boat Business

Words ©Chris (Seabuddy) Brown, photos by Aston Martin, et al

The very first model will be a 37’ sport boat This boat will be introduced late in 2015. It will be named the AM37 and the Aston Martin name and logo will be on the boat.

Quick facts- there are some heavy hitters in the boat business in bring this boat to market. Henk de Vries, Director of Feadship is on board. As is Mulder Yacht Design. See Mulder’s 76 MPH yacht Moonraker.

And do not forget Aston Martin.
Here is a quote…The AM37 combines the highest degree of technology and innovation in a genuinely unique manner that is sure to delight those who understand the Aston Martin credo of ‘power, beauty and soul’.

Aston Martin is a 103 year old car company that won Le Mans outright with Carroll Shelby in 1959.

And they won their GT 1 class in 2007.

They are a small car company, but they have $312 million in new funds to expand from investors. The investors and management want to company to expand, particularly with its influence with women. There are naming deals for Sunglasses and Travel Accessories.

Aston will get future engines and electronics from Mercedes Benz. Mercedes may have Aston Martin make their very limited production Mayback models, as it is believed that Aston is better suited for limited production, than a big company like M B..
There is talk of an Alabama Aston Martin plant, near the Mercedes one.

The AM37 will be made in the UK is seabuddy’s current understanding, but not inside the Aston Martin Gaydon, Warwickshire UK headquarters.

Engines will be gas of diesel. Currently the thought is to power the gas engine closed deck sport cuddy cabin boats for a 60 MPH WOT top speed and the Diesels for a 50 MPH top speed. So, they are not Go-Fast boats. Rather, think Riva Aquarama, undated to today’s technology.

ACBS Classic Boat Show and Festival Award Winners #1

Words and photos © Chris (Seabuddy) Brown

A black hulled single engine Cigarette swept its classes first time out of the barn. While she was up against a fast Nova/ Allmand 19, the judges all agreed that Lotus was the clear winner. Everyone was pleased that the number of off-shore fiberglass boats in attendance was on the upswing at this year’s boat show. Each show of the 57 diferent clubs have a slant to their show. It looks like this Mid-Atlantic Father’s Day Classic Boat Show / Festival is beginning to get the go-fast in rough water boating crowd.

Lotus is not a race boat, just a high speed, wave splitter cruiser/day boat for a young married couple and their dog. The boat is re-powered with a replacement, updated big block 496 cu. in. Chevy engine with EFI, for the ease of starting and shifting. The newer engine takes away show award points, but the ease of use of the newer intake system makes for a better boat, day in/ day out.

What does not take away points is the black hull finish. This boat has over 1,200 hours of sanding to get that flawless finish, up from a production boat building level of finish. She was finish sanded to over 2,000# grit paper. It is a AWLGRIP finish that one sees now.

The deck, cockpit, and the wood trim also took lots of finish work. Basically, it is several layers of epoxy. The cockpit dash was also updated with new instruments and other details. However, the vinyl seats and trim are several years old. There is a longish vinyl pad under the foredeck. It is out of the weather and in a pinch, one could overnight in this limited cabin.

Figure on a 45 MPH cruise and about a 70 MPH top end as powered in this 1972 24’ classic GO-FAST cruiser re-do.

 

New marine fuel winter storage product

marine fuel stabilzer sta bil 360 winter storage boat

Sta Bil 360 Marine

 

Sta Bil 360 Marine adds new protection to your boat and its engine(s) for 2014. In many parts of the country, boaters have an off-season period. This can last four to 8 months depending on your home port. All you boaters that slip their boats in Key West, well Seabuddy is not talking about your boating fuel habits in a direct way in this write-up.

For the rest of us gas engine seasonal boat owners, let me suggest a few pointers.

Warning, I am not a chemist, I am simply passing on personal experiences and some advertising messaging put out by major players within the marine trades.

Put your boat away with the gas fuel tank 95% full.

At the beginning of your last fill up, pour in 1 oz. of Sta Bil 360 Marine for every 5 gallons of gas you intend to put in your boat.

Think about buying your Sta Bil 360 either at your nearest convenient marine store or at a low price shop. Google search “Sta Bil 360” at Walmart and Amazon.com. Watch your final costs including shipping and sales tax. Use half as much at every fill-up during the season.

Here is a quote from the fuel stabilizer maker “STA-BIL 360 MARINE offers comprehensive protection by releasing a microscopic corrosion preventing vapor inside the fuel system that coats ALL metals parts, including the fuel tank, fuel sending unit, valves, carburetor, fuel injectors and intake manifold. It’s like fogging oil for your entire fuel system, offering “360 degrees” of corrosion protection and is safe to use in all types of gasoline – from ethanol-free fuel to E85.

STA-BIL 360 MARINE accomplishes everything our current STA-BIL products offer, including keeping fuel fresh, removing water, cleaning the fuel system and more, but this revolutionary new product provides an exciting new level of protection for ultimate performance. For the first time, STA-BIL 360 MARINE delivers corrosion protection above and below the fuel line by releasing an innovative vapor that coats all metal parts within the fuel system to prevent corrosion.

Once poured into a tank of fuel, STA-BIL 360 MARINE will provide a vaporized corrosion inhibitor coating for up to 12 months in a stored boat or equipment.”

This product is new for 2014 and it won the International Boatbuilder’s Exhibition & Conference (IBEX) Innovation Award in the Boat Care and Maintenance category.

IBEX is organized by the National Marine Manufacturers Association (NMMA) and judged by members of Boating Writers International (BWI), the award recognizes innovative distinction from other products currently being manufactured, benefit to the marine industry and consumers, practicality and cost-effectiveness.

Two or Three Engines for you?

Caution, if you pick the three engines choice for your boat, watch your propeller selection, lower unit life, and fuel mileage. Both choices are good choices for a $350,000 new Center Console boat. Say, one in the mid-30s in length.

Prop selection. In a three engine power set-up, the center engine uses a different spec prop than the two outside ones to properly match the engines to the boat. With two engines, the two propellers are the same spec and mount on the transom at a uniform height. This mounting height may, or not, be true for a triple engine boat.

With the different prop spec and other correcting mounting adjustments necessary for a three engine boat, the life of trouble-free use of the center engine seems to be in question. Often, the lower unit below the cavitation plate has a shorter life within the center engine, compared to the two outside engines. Make sure that the warranty of all your engine parts are covered by a factory guarantee plan with your three engine boat and that it clearly states that all three engines on your one boat are equally covered and any warrantee plan extension is also available with the same equal engine coverage -FOR ALL THREE ENGINES.

Seabuddy took two center consoles listed below, one with two engines, one with three. In all of these sets of rounded numbers the three engine boat is listed first. Length 35’ 6”, 33’ 6”; Beam 10’ 10”, 11’ 7”; 90 GPH fuel burn at 54 MPH, 68 GPH at 51 MPH; 33 MPH with 33GPH fuel burn, 31 MPH with a 25 GPH fuel burn.

 

Bow Rider Helm. Do not miss this one!

Going to a boat show? Take more than a look and sit in, adjust, and observe just how good the helm station is in a 264 FS bow rider.  Study the fit and high level of finish within the cockpit that it leads your eye and hand to experience major improvements that Monterey Boats is bringing to the marine marketplace. Look at the eyebrow over the dash and the gauges. It is as good as it gets for 2014!

Board the boat from the swim platform and see the sun pad that changes into a rear seat.  Try the comfort of that seat and others. Definitely try the driver’s command chair and ALL of its features. Feel the shifter and eye the gauges their sight lines.

This is a 26’ 7” LOA bow rider runabout by Monterey Boats out of Florida that sets a fresh standard of luxury, effectiveness, and comfort for a day boat. Helm chair features, vinyl choices, storage, and comfort underfoot have all been addressed.

This boat has an 8’ 6” beam and is easy to trailer. She has a sweet running hull that takes an afternoon chop well and uses extra power easily. Special hull features are valuable items in terms of performance on the water. See the chine detail for yourself at a boat show. Power this one up. Check the gas tank capacity, also, as a for instance. Ask about these hull design and construction features and decide what power choices will do the job for you. The Monterey Boats 264 FS is a hit in the boating marketplace and a do not miss boat to see at a boat show.

Seabuddy thanks Monterey boats for these photos.

Jeff Hunton 2014 Powerboat coming to US

Offshore racer Hunton designs and builds fast boats for Europe and the Med. He has raced in major races across the pond back to 1975.  His boat designing and fast pleasure craft boat building  started in 1979. Now one of his sport boat designs is coming to the USA.

hunton powerboat go fast 37 marine boat photo image

Jumping a wake shows her bottom shape

She is a 37’ 3” 65 MPH Go-Fast with luxury that has a 8’ 6” beam.  Boats destined for the United States will have 860 horsepower, while, due to fuel taxes, European boats use Volvo diesels. Watch a part of the video… http://www.youtube.com/watch?v=5rrMO3Gldak skip forward to 96 seconds into the 2:21 second video and then watch for a minute.

Hunton Powerboats crafts this boat in Hampshire, England for the bespoke crowd. She is not a racer. She is a fast pleasure boat (or day boat) with overnight (extended weekend) accommodations.  The boat comes with a bow thruster, an electric anchor winch, and teak accents in the cockpit/ side decks. Think Gentleman’s Racer, not boat racer.

The company is well known in its current marketplace, thus the expansion to the U S. This is not an easy market to conquer as it is a big one (with many sub-sections), one that requires that all the electronics, mechanical, and systems be changed here, or installed here by a sub-contractor (thus requiring Hunton shipping incomplete boats across the Atlantic), or all these things shipped in from the U S, installed on a boat, and then the completed boat package being shipped back to the U S. Check for yourself how they are handling this, including service manuals and local warrantee support details.

Wood Runabout takes off level and rides level

Here is a modern boat that brings a real flat take-off and ride to a sport classic style wooden boat. Take a look here..    http://www.youtube.com/watch?v=6J08psf7PVI  and see her flat take off and running angle. It is really something else if you are used to a deep vee bottom boat.

Why? Where is the magic that delvers that wonderful take-off? Bottom shape, chine width at the transom, a good weight balance point accomplished by engine weight location, and direct drive shaft angle; all combine for the accomplished goal.

clarion boats 23 wooden runabout straight shaft inboard sport boat

take a look at her bottom

She is a straight inboard with a double cockpit forward layout. That allows the engine to come forward within the hull. Plus she can have a straight drive, not a vee-drive. And she is family friendly design while underway.

This is a 23’ 4” hand-crafted boat with a 6’ 6” beam.  She is a planked, cold molded original design. Clarion does not stretch or shorten boat designs to fit different model lengths like Fountain Power Boats. They computer cut their frames and hand fit their layers of planking.

Most boats use a 350 Chevy Mercruiser engine of 300 horsepower for a great push in the back take-off and a equally thrilling top speed at WOT. Other engines are available but few owners choose them.

A wood runabout with a cockpit trimmed in fine leather and with proper chrome hardware sparkles at pier side or on the open water. Nickel hardware is a special order item. The level of finish on all three materials is stunning.

Does this boat builder build and restore “over-the-top” boats? Yes. Their shop has been around for years. A wooden boat shop servers the boating market via it’s craftsmanship in 2013.

Buyers want quality in their wooden boats. A good ride is not enough. Few utilitarian wood boat builders are around anymore. Folks want a bright finished mahogany runabout or utility now. At sunset, a wooden boat owner wants a piece of art that one rubs a hand over and says, that is my boat and she is a beauty.
