About Us

Sea Thru Limited was founded by Brian Casey in September 1989 under the name of Boat Windscreens.

Working at Reflex Products Ltd in the mid-eighties, the supply of boat windscreens from traditional suppliers was difficult. Reflex made the commitment to produce their own range of screens.

The task was undertaken by Brian Casey. After two years it became obvious that a specialized company would be appropriate to produce the product. With the support of Reflex Products as a major customer Boat Windscreens commenced trading. This was a part time venture working in a domestic garage from home.

The 1988 New Zealand boat show attracted the attention of McLay Boats who then became a key customer. From these small beginnings, Sea Thru Ltd was incorporated on the 9th of February 1999.

Six moves and many years later Sea Thru Ltd now employs many staff. In October 2006 we opened a new purpose-built factory. This is a tilt slab structure of 1500 square meters.

We now supply a major portion of the New Zealand trailer boat market and continue to show growth and leadership to the industry through quality products and our best service possible.

Commitment to the industry is key to the Sea Thru Ltd culture.
