Center Console Enclosures

Designing and fabricating enclosures for center console boats are a pleasure and rewarding as they serve many different functions.

I have made more than 40 different enclosures for center console boats in all sizes, designs  and colors.

Glass material ranging from 1/4 inch poly carbonate to vinyl Strata Glass

Center console UPHOLSTERY

5076953_20150501100757667_1_XLARGE.jpg

Working with Rob Lyons / Ocean House Marine I must have done over 100 different center console suites.

Having the Scout, Contender and Boston whaler contracts and a staff of 12 permanent upholsterers over a period of 3 years I cannot count the projects we did.

Our work was obviously well received or we would not have had the repeat business.

Center Console Cover sets

854054973.jpg

Templating covers to fit correctly is important. Although I have made over 100 sets the boat manufacturers and owners keep changing their designs or equipment making it difficult to keep a set of patterns in stock. 

The cover sets are normally templated and then patterned prior to cutting and stitching 

Full boat covers for high speed trailing I have tested at 65 miles per hour which should weather most storms.

Often the covers are designed to attach to other canvas enclosures or parts. This is not a problem using track systems and zippers with velcro flaps.

T-Tops & Frame work

contender-39-fisharound-0067.jpeg

I have done a lot of work through Rob Lyons and Ocean House Marina, however frame work and T-Top designs I normally template , bend the frames tack weld into position and then transport out for final welding and powder coating.

Although I do weld some simpler designs in Stainless Steel I have the aluminum frames professionally finished by sub contractors. 

The designs are mine and they are all fabricated to incorporate the upholstery, seating, electronics, steering and bimini or hard top canopies. 

When designing and fabricating a T-Top or enclosure system one need to pay attention to the over all design of the boat, weights and functionality whilst keeping the client happy.

Over 20+ years I have done a number of different T-Top towers and bimini style projects for both hard and soft canvas tops. Each has its own unique design as per client requests. My first question is normally to find out whether there is to be an enclosure to be added at some point.  This is a major factor in the design as a track system needs to be accommodated for the adherence of an enclosure. 

The rod holders are always the most important feature for the boat owner but the angle positioning and out rigger systems are simple add-on's that can be incorporated into most T-Top frames with little adaptation.

initial Drafting

toe.jpg

1. The first step is to draw out a basic design of the clients requirements aesthetically.

2. This does not always work with what the lines of the boat.

3. It is important for both the canvas company's reputation and the resale value of the boat  that the design of the dodger follows the line of the boat and functions correctly with all running gear on board.


Client Relations

        Modern Wall Hangings

1. Once an initial draft of the dodger design has been done and accepted by the client / boat owner the computer draft can be created which helps in the patterning process.

2. Special attention needs to be made to the clients height and visibility above and beneath the dodger by the hlmsman. 

3. At this point a 3D spacial model can be created to ascertain clearance space between the dodger frames and the winches / running gear.

4. Now the client can have a better idea as to the functionality of the dodger design and any limitations it may have . Compromises are part of the process.


Sizing 

maxresdefault.jpg

1.Throw or length and width. are the first along with height that need to be considered.

2. Many of the newer boats lend the dodger design to squarer corners which maximize the interior space but make the outside deck walkways narrower.

3.Special attention to Jib lines need to to be made as newer boats have furling lines and cleating systems that also nee to be taken into account. 


BOOM HEigHT WITH VANG CONSTRICTIONS

072009_1951_Buildingaha1.jpg

1. Boom height with vang constrictions. along with traveler and main sheeting is another running gear compromise that affects the dodger design and functionality. 

2. Depending on the length of the main sheeting traveler and the expertise of the sailor the curvature of the aft bow for the dodger can be dicussed. the rounded curve will be a safer choice if the main sail jibes but will limit the coverage and protection the dodger offers. 

3. Sharp corners present snagging locations for the main sheeting and could cause serious damage and or injury in the case of a hard jibe.

Often re-cutting the sail can optimize the dodger sedign both for aesthetic and functionality reasons. Whether the client is willing to go the extraa dollar mile ... Well that a budget question.


designing for Enclosure extensions 

AFT-CORNER.jpg

One normally designs a dodger as a stand alone piece of hardware. However, taking into account what the next owner might want or what the current owner might actually require  and possibly order the next time round is again something we need to take into account,  

The lines for the enclosure need to be as simple as possible. The simpler you can make the dodger and incorporate the features for for connectors, the easier it will be for an enclosure to be incorporated. keeping where possible a srtaight line from the bimini to the dodger is ideal but not always possible.

Please at this point take into account weather! 


Windage 

j122_cfd.JPG

Here we need to take into account the weather and the amount of windage the dodger and an enclosure can present in adverse conditions. As the wind picks up  a large enclosure while offering comfortable accommodations  can cause a boat to have increased weather helm and in severe conditions 40 knots plus can inhibit the boat from maintaining a course.

Please try when deciding on a design to enable the dodger and enclosure to have reasonably rounded bows and curve to enable the vessel in adverse weather to perform as intended. 

If on the other hand you have a large motor on board and the vessel is over 35 tons you don't need to pay as much attention to this factor. 

Performance yachts normally need special attention to detail.
