Presenting the GOZZARD 51 MY

1. STRUCTURAL.

1.1 General.

The builder’s workmanship is to be done at a level equal or superior to that exhibited by a current Gozzard 44 (2001 Vintage). All FRP calculations are based on a hand lay-up of alternating layers of glass mat and a knitted double bias E-Glass cloth using marine grade resins. All laminated schedules are recommended and approved by the material suppliers and are based on existing technology and known successful examples of comparably sized vessels.

1.2 Hull Construction.

The hull will be molded using the “ATC” Bead and Cove method on a male form. The laminate, as with all Gozzard’s, will be a cored sandwich construction. The “ATC” A550 and A600 Core Cell foam core increases panel stiffness, strength, impact resistance and sound/thermal insulation while maintaining an excellent weight to strength ratio. A marine grade “Cook” Iso-DCDP blend resin is used throughout except for the outer most layers where Duratek Vinylester resin is substituted for superior osmotic resistance. All fairing compounds are either vinylester or epoxy based and are kept to a maximum thickness of 1/8”.

The coring material is eliminated in the areas of the sheer line, centerline, keel, rudder post, and thru-hulls creating a solid FRP lay-up in these areas.

Details:

A.) The outer skin of knitted double-bias E-glass cloth and mat is built up to a thickness of approximately ¼” above the waterline and 5/16”below with additional re-enforcing in the bow and other high stress areas.

B.) The core material is 1” Core Cell in the topsides and 1 ¼” in the bottom. The core density varies according to load. The bow sections have A600 to accommodate the loads from pounding at speed.

C.) The inner skin is also a knitted double-bias E-glass cloth and is similar in thickness to the outer skin.

D.) The solid laminate areas are built up to the following thickness:

Centerline 1 1/8”

Keel 1 5/16”

Sheer 7/8”

Hull Flange ½”

Thru-hulls ¾”

E.) Finish above the waterline is “Awlgrip” in any normal color and style. Below the waterline is finished with 15 mils (dry) of “Inter-Protect” 2000 and the bottom anti-fouling paint of your choice.

1.21 Stabilizer Pre-install

To accommodate the possible future installation of stabilizers, the area just aft of station 6 located below the waterline and above the chine will have the core removed in lieu of a solid glass laminate. This area will also be further reinforced with extra laminates to eliminate hull flex in this area should stabilizers be installed.

1.21A - Stabilizer System - RS600 Gyro Roll Fin Stabilizer System. Hydraulic power is provided by a Vickers V10 direct double belt drive pump custom mounted to the port engine. Water cooling for the hydraulic system is provided by a direct single belt drive Jabsco #1673-1001 bronzed impeller pump custom mounted to the port engine. A ¾” intake thru-hull with a Perko bronze strainer supplies the water.

1.3 Deck Construction.

The deck is a molded FRP sandwich construction with ½”, ¾”and 1” A500 Core Cell. In areas where equipment is to be installed, the coring material is eliminated created a solid laminate. The outer and inner skins are built up to a thickness of approximately 1/4”. The deck flange is solid and built up to ½” in thickness.

The hull deck joint is bedded in 3M 5200. A teak cap rail finishes the joint

1.4 Rudder.

The rudder stock is 2” diameter solid stainless steel. The rudders are FRP custom built from A600 CoreCell with stainless webs welded to the SS shaft. They are designed to be more hydrodynamically efficient than available bronze foils. Upper and lower bearings are installed with a shaft seal.

1.5 Skeg.

The integral skeg is a solid, heavily reinforced FRP construction.

1.6 Bulkheads.

All main or structural bulkheads are constructed using cored FRP laminated for superior strength versus weight and total rot resistance. All bulkheads are glassed to the hull and deck before the interior trims are installed. Where possible all wooden furnishings, shelves, seat tops, dividers, etc., are glassed to the hull or deck to minimize unsupported panel size.

2. DECK.

2.1 General.

The deck, like the hull is finished with Awlgrip linear polyurethane paint. All horizontal surfaces (walkways) are coated with Awlgrip non-skid, a sand type anti-skid surface. The aft deck is finished with teak decking for improved durability, excellent wear and dirt resistance. The teak decking is glued to the deck (and together) with Sika-Flex 290 Deck Caulk keeping external screw fasteners and plugs to a minimum.

3.11 Generator.

A Westerbeke 12 KW, 3 cylinder diesel generator in installed in it’s own sound box inside the insulated engine room. Instruments include oil pressure, water temperature and hour meter. The generator is equipped with an automatic shut down system. The exhaust is routed through a water separation system that exhausts the gas above the waterline and the water below the waterline to reduce noise.

3.11A – Upgrade to 15 KW.

4. ELECTRICAL.

4.1 General.

All ship’s wiring is marine grade tinned copper including primary battery runs and is installed in accordance with ABYC specifications. All wires are coded and colored for easy identification. Schematics and a legend are supplied for servicing. All connections are crimped using tinned fittings with colored heat shrink covers for stress relief and easy identification.

4.2 DC Electrical System.

The ship’s main DC Voltage system is 24 Volt. There are 4 separate battery groups. The house batteries consists of 4 - 8Ds located aft and 2 – 8Ds forward. The forward batteries are positioned to prevent voltage drop at the thruster. These batteries combine for a of total 750 amp hour at 24-volt. The engines each have a dedicated pair of 8D (24-volt) series diesel starting batteries. The generator has a dedicated 24 series 12-volt diesel starting battery.

4.2A – Credit 4 x 8D house bank, upgrade to 12 x 2 volt industrial gel cell bank.

4.2B – Credit 2 x 8D fwd bank and upgrade to 2 x Optima deep cycle with solenoid with diodes for engine charging.

4.2C – Credit 2 x 8D engine starting batteries.

4.2D – Upgrade Generator starting to Optima Red Top.

The ship also has a 12-volt system for electronics and other lower amperage draw equipment. The 12-volt is produced through a high efficiency DC to DC invertor that basically center taps 12-volt from the 24-volt system while balancing the batteries. If this system were to fail, backup is provided through the 12-volt generator starting/charging circuit.

4.2E – Upgrade DC to DC converter to 100 Amps and restock original 30 Amp.

All batteries are of Gel-Cell construction to maintain similar charging properties and virtually maintenance free operation. The system is wired for total redundancy. For emergency starting, the main engines can access the house batteries.

Each main engine is supplied with a 70 amp 24-volt alternator that charges the batteries automatically through an isolator. Each engine is capable of thoroughly charging the system independently for redundancy. The generator battery is charged from the standard 35 Amp internally regulated OEM alternator supplied with the generator.

Alternatively, when the vessel has access to a 120 volt AC source, all batteries may be charged from the 65 amp automatic Freedom 2500 charger/inverter. The house batteries have direct access to the automatic charge (up to 65 amps) while the engine battery(s) are charged via a separate current limited Echo Charger. Another Echo Charger charges the bow battery bank.

The DC system is monitored by a Link 2000, (a power consumption meter for your main battery bank). It is integrated to the Freedom 2500 invertor/charger, but unlike the Gozzard 44, not the twin main alternators. The Link 2000 controls the invertor/charger 70-amp charge rate, as the batteries require through a multi-stage voltage regulator. The 70 amp alternators also have a “smart” multi-stage external voltage regulator but it is not integrated into the Link 2000. Each alternator is still equipped with the standard internal voltage regulator, which could be converted back as further additional backup.

Each battery bank is equipped with a main disconnect switch. Each main disconnect switch can be linked in parallel or in isolation to the other battery banks for emergency access.

4.3 AC Electrical System.

The ship’s AC system is 230-volt single-phase 60 cycle. AC power is supplied by a ship to shore connection, the on board generator, or from the 24 volt DC system via the invertor. All outlets are GFI protected. Two separate 115-volt load groups are supplied by a single 240-volt input.

The ship to shore connection is made through a single 50 Amp 230-volt shore cord. There are bow and stern shore chord connections with a transfer switch to isolate the connection not being used. There is a primary disconnect switch within 6’ of the deck connection and a secondary disconnect at the distribution panel.

4.3A – Credit second shore inlet and transfer switches and original shore chord.

4.3B - Stern shore chord will exit via a Glendenning Cable Master System through the transom. 4.3C - This unit also has remote control.

Limited AC power can also be generated from the 2500-watt inverter using the ships DC system.

To operate the entire AC system away from the dock a Westerbeck 12KW-diesel generator (see 3.11) is installed in the main engine room. It is large enough to support the entire ship’s full AC requirements.

The system also incorporates a galvanic isolator to control stray electrolysis.

4.3D – Upgrade to Charles Isoboost power transformer in lieu of galvanic isolator.

4.4 Distribution Panel.

The main DC and AC distribution panels are located in the pilothouse. The distribution panels are custom made using magnetic circuit breakers with indicators and back lighting. An analog voltmeter is integrated into the DC panel allowing you to test the voltage at the house bank, main engine and generator starting batteries. An analog DC amp meter measures amp draw at the panel. Similar meters are installed for the AC side and measure both load group #1 and #2. A reverse polarity light is included.

A 12-volt DC distribution panel controls 12-volt accessories.

4.5 Bonding System.

The vessel is fully bonded and is equipped with 4 external zinc anodes. The vessel’s primary zinc is a Vetus Type 25 located aft. The thruster is equipped separate zinc, as are the propeller shafts, trim tabs and struts.

4.6 Lightning Protection.

The lightning protection system has all pulpits, lifelines and antenna arch grounded with 4 gauge tinned copper braid to a large Dyna-Plate (est.64sq.ft.)

5 PLUMBING.

5.1 General.

All hoses are premium quality marine grade and are UL and CG approved for specific application. The fresh water system uses the Whale 2000 tubing system. Made of hard plastic and colored blue for cold and red for hot, this system does not use hose barbs and clamps, rather quick disconnect fittings that are much easier to service.

5.2 Fresh Water System.

Three separate water tanks supply fresh water, each with it’s own fill, vent and draw tube. Custom made, maximizing the available space, the FRP tanks are lined with a FDA approved epoxy to ensure no taste transfer and have removable lids with access panels for easy maintenance or service. A manifold is used to control water draw from each tank, thus allowing you to control the boats trim as the water is consumed. The level of water in each tank can be measured using the Hart Tank Tender located in the nav station. Total water capacity is set at 400 gallons but can be modified to suit specific needs.

The largest Flowjet centrifugal pump available with filter and accumulator tank supplies water pressure. A pressure regulated shore water connection is installed to by-pass the on-board system if dock water is available. Additional fresh water outlet is included at the bow. Hot and cold are run to 3 head vanities, galley sink, both showers, washing machine and cockpit shower.

5.2A – Upgrade shower center set with thermostatically controlled units.

5.2B – Soap dispenser install.

A 20-gallon hot water heater supplies hot water. This heater can make hot water using a 120-volt electric heating element or a built-in heat exchanger using the closed loop engine coolant system from the port engine. A mixer valve is installed to regulate the water temperature at 140 degrees to prevent the 180-degree engine coolant heat exchanger from overheating the water.

A Seagull water filtration system is plumbed into the galley, ice maker and both master staterooms to provide clean taste free drinking water from a tap.

5.3 Waste Management System.

The boat is designed to incorporate 3 separate Vacu-Flush marine heads. A single FRP holding tank can be emptied using a deck fitting or the onboard macerator system. Fluid levels are measured using the Hart Tank Tender. The holding tank utilizes a cross ventilation system by incorporating port and starboard vents. The advantage of this is that air is always moving through the tank, lessening the odor, and if one vent becomes blocked you always have a spare. Total waste capacity is set at 100 gallons

5.3A – Upgrade to HeadHunter system complete with 110-volt pressure system. PVC plumbing used where ever possible.

5.3B – Install SeaLand charcoal filters in vents.

5.4 Grey Water System.

All sinks drain directly overboard through a seacock installed in close proximity and within easy reach.

Independent shower sump pumps are supplied for each shower and drain (pumped) overboard. The self-contained units are automatic and have strainers built-in. They are also used for the air conditioner condensation drains.

5.5 Diesel Fuel System.

Diesel fuel is stored in four baffled aluminum tanks. Connected by a manifold, fuel can be returned and picked up in any combination allowing you to maintain trim or to re-filter your fuel supply. Large clean outs are built in to the tank tops for easy servicing. Capacity is set at 800 gallons or approximately 200 gallons each.

Two Racor 1000 filters are supplied with double redundancy in mind. A simple valve system allows you to be able to by-pass either filter or even change one out on the fly. Fluid levels are measured electronically with the fuel gauges located near the helm stations.

5.5A – Install Vetus overflow containment system.

5.5B – Install dedicated Hart Tank Tenders for fuel system.

5.5C – Install fuel transfer pump.
