Mr Andrew Field gave Tecsew the following testimonial:

We own an Aphrodite, a high quality Swedish yacht similar to a Najad. In common with many Swedish yachts, she has a Sprayhood attached to a fixed glass screen and an all over Cockpit Cover that attaches to the rear edge of the Sprayhood.

When new, she arrived from the yard with a well-designed, Swedish manufactured Sprayhood and Cover. Inevitably both items eventually wore out and replacements were ordered from a South coast manufacturer. Although these replacements fulfilled the required function, they lacked many of the clever details of the originals and the fabric was not of the same quality.

So when the time came to replace these items again, we were determined to obtain exactly what we wanted and spent a great deal of time researching the market. We came across Tecsew and as they do not exhibit at the Southampton Boat Show (due to manufacturing commitments) we opted to visit their manufacturing facility in Gosport.

We were very impressed with the amount of time that John Bland spent explaining how Tecsew operates and running through the numerous options available to us. We were particularly impressed with the use of state of the art electronic measurement that is then translated into 3D software, allowing the customer to see exactly what will be produced and to make changes, if required.

Quotations were duly provided and we settled on a new Sprayhood + Cover in Sunbrella Supreme with new stainless steel frames for both items.

John Bland visited the boat, took all the electronic measurements and discussed various points of detail, which included some suggestions for some significant improvements. We then received a set of both 2D and 3D images showing the proposals. We requested a few minor tweaks here and there, which were duly made and a revised set of images was produced. Once we were happy with all aspects of the design and the fabric had arrived from the USA, production commenced.

We are delighted with the very high quality of the end product and the fact that everything is exactly as we expected. We have since ordered a new Winter Cover from Tecsew and I have recommended Tecsew to other discerning boat owners.

In summary the whole operation is so professional & knowledgeable with great attention to detail and the whole process went through without hitch or delay.

  • On-Site Framework Adjustment: Adjusting and fixing frameworks on the boat for a perfect fit.
  • Canvas Measurement and Digitisation: Measuring and digitising canvas using traditional methods and CAD.
  • Canvas Cutting and Marking: Following CAD guidelines for precise canvas cutting.
  • Machinist Involvement: Detailed canvas preparation by skilled machinists.
  • Benching Process: Insertion of fittings, eyelets, and straps for functionality and durability.
  • Final Assembly on Boat: Fitting frameworks and canvas on the boat, ensuring accuracy.

New Method using 3D Design and Advanced Technologies:

  • Initial Boat Consultation: Meet on the boat, agree on design specifics, and digitally capture cockpit dimensions.
  • Design Development: Use advanced software to create 3D designs, aligning with customer briefs.
  • Collaboration & Approval: Electronically send designs for customer review and invite for in-office discussions.
  • Precision Drawing Conversion: Convert 3D designs into 2D formats for accurate cutting.
  • Framework & Canvas Production: Create a framework from CAD models and prepare the canvas for precision sewing.
  • Detailed Benching Process: Insert fittings, eyelets, and straps for enhanced functionality and durability.
  • Final Assembly: Fit framework and canvas on the boat.
