UPD Plastics Acrylic Boat Windshields

Overview

Most production boats under 30 feet have a plastic windshield, and when the plastic finally crazes, cracks, or goes over the side, the boat builder has usually stopped stocking it. UPD Plastics in Davie, Florida, is the company that kept the molds. Its founder, John Carney, dates the business to 1975 under earlier names (Customized Acrylics in Miami, then Custom Acrylic Creations in Hialeah), and the UPD name arrived in 1999. The corporate entity on file with the state of Florida dates from 2009, so the 50-year claim rests on the company's own account of its predecessors, but it is consistent with the forum record, which has owners recommending UPD as far back as 2012.

It is a small shop. Data brokers estimate four employees. The whole business runs on a pattern library that UPD describes variously as "over 3,000 different universal boat windshields," "1,000+ windshield molds," and "more than 2,700 different OEM stock molds," across roughly 100 boat brands. Whatever the exact count, the practical test is simple: go to the manufacturer list, find your builder, and see whether your model and year are there. For Boston Whaler, SeaCraft, Mako, Parker, Premier, Key West, and a hundred others, the answer is usually yes.

What you get

A windshield formed from what UPD calls marine-grade acrylic, CNC cut, with polished edges, made to order in the thickness and color you pick. Pontoon shields are 3/16 inch, bow shields and small consoles 1/4 inch, and most Boston Whaler and SeaCraft consoles 3/8-inch "heavy duty." The tint chart lists ten options: clear, coke bottle green, transparent blue, three grey smokes, three bronze smokes, opaque white, and opaque black.

The box holds the shield, a drill bit, grommets, spacers, and mounting instructions. Listings that show no holes ship undrilled; you drill your own using the old shield as a guide. A blackout stripe is available only if you send in the original with authorization, and UPD keeps every original for mold making, so photograph it first if it matters to you.

What UPD does not say is whether the sheet is cast or extruded, and it does not name the sheet maker. That is a real gap. Cast acrylic resists crazing and solvents better and holds tighter optical tolerances; extruded forms more easily and costs about 20 percent less. Our cast vs extruded explainer covers the difference. Ask which you are getting before you pay.

How ordering works

Everything goes through online forms; there is no phone ordering. The site routes you by boat type: bass and pontoon, no-windshield (console measurements), center or dual console, wraparound, or flybridge. If your pattern is on file, the listing shows an estimated price range, and you compare UPD's schematic against your old shield yourself. UPD is explicit that it will not tell you whether a pattern matches: "a match is not determined by year and size of boat, but is determined by a schematic comparison," and the company "does not offer opinions." A printable corner-radius chart helps, if you print it at 100 percent.

If your pattern is not on file, you send the old shield, or a template, and UPD makes a mold. It says it does this at no charge where other shops charge up to $300, and that it is the only company in the industry to do so. That last part is a superlative we cannot check. What is clear is the return deal on a send-in: UPD covers return shipping up to $100 on the replica.

Tolerance is ±1/4 inch, which is normal for formed acrylic and worth knowing before you drill into a fixed aluminum frame.

Lead time

This is the number to internalize. The product pages state a "minimum fabrication schedule" of 60 to 90 days, with a 30-day expedited option only for shields already listed, not for new molds. Owner reports on The Hull Truth span two to three weeks for a repeat order from a marine shop that has bought there for 15 years, seven weeks for a first-time Donzi owner, and, in one Bayliner owner's case, five months. A 2018 poster who had bought several shields put it plainly: "Do not go to him if you're in a rush. He does however deliver a quality product every time."

Fit and quality

On the product itself the record is good. The same 2018 owner said every shield "fit exactly as I expected." A Striper owner in 2015 wrote that the replacement "far exceeds the OEM quality," and when UPD made a mistake on that order it "covered all the return shipping and shipping for the replacement." A Jupiter owner in 2017 had a minor fit issue corrected. A Lund owner in June 2026 summed up the consensus: "did great work, but they're not the fastest." A Boston Whaler forum member noted in 2012 that UPD was the only source for Newport-specific windscreens, and a Whaler dealer resells UPD shields at UPD's own list price rather than making its own.

One competing fabricator claimed in 2014 to "get a lot of their re-do's." That is a competitor talking, so weigh it accordingly, but it is the only quality complaint we found against the volume of fit praise.

Service and the fine print

The complaints are about the counter, not the shop. Yelp sits at 1.8 stars across roughly 16 to 19 reviews, with at least one reviewer saying the owner declined their order after a negative review. A 2014 Hull Truth poster called the company "condescending and rude" and had an order cancelled after payment, with the return at the customer's expense. Another owner in 2022 "tried getting in contact with these guys several times without success." Against that, the Better Business Bureau rates UPD A+ with one closed complaint in three years, and the eBay store shows 100 percent positive feedback over about 900 sales. Both are true; they measure different people.

The policies page deserves a full read. Giving UPD a form of payment "constitutes a contract" to make your shield, and a shield already fabricated "cannot be canceled." The 30-day return policy sounds generous, and UPD does pay return shipping on qualifying returns, but it requires the shield be uninstalled, undrilled, still in its film and packaging, and authorized in advance, and it excludes custom and special orders, color or thickness changes, fitment errors on your side, and "products fabricated according to the purchaser's selected schematic." Since every shield is made to order and you select the schematic, that last clause can cover most orders. Warranty terms are not stated anywhere; crazing "from environmental causes" and fit problems from customer measurements are specifically excluded, and UPD's blog warns that Windex and other solvent cleaners will "void manufacturer warrantee."

Price

In September 2026 the estimated ranges shown on pattern listings were $113 to $261 for Premier pontoon shields in 3/16 inch, $207 to $528 for Boston Whaler shields (a 2017 170 Dauntless at $325 to $338, a 1971 21-foot Outrage at $374 to $528), and $325 to $726 for SeaCraft, topping out at the 32-foot Master Angler. The eBay store lists finished shields at fixed prices in the $149 to $386 range. Forum owners paid "a tad over $300" for a Donzi shield quoted at about $1,000 locally, and $675 to $700 for a 38-foot Bayliner. Shipping is calculated after the order, so add that; UPD does not publish freight examples.

For context, an owner quoted Taylor Made for a curved glass windshield in 2022 reported a seven-month lead and a price above $12,000. Specialty Marine's ready-made Whaler shields start at $268 and are the faster answer if you own a Montauk or Outrage.

Caring for an acrylic windshield

UPD's own care page is sound and matches the sheet makers' guidance: soap and water, then a plastic polish such as Meguiar's PlastX, Mothers Marine, or Star brite; never ammonia or alcohol cleaners, solvents, or insecticide overspray; and no hot tarps against the sheet. Our scratch repair guide covers polishing out the fine haze that salt and wipers leave. ABYC H-3, the voluntary glazing standard for recreational boats, allows acrylic for windshields and asks for at least 70 percent light transmission, which every clear and light tint passes; the dark smokes and bronzes are for a bimini-shaded helm, not a night run.

Who should buy it

Anyone whose boat is in the pattern library, who can wait two to three months, and who wants a replacement that fits at a fraction of an OEM or custom-glass price. Do the schematic comparison honestly, choose a light tint for an unshaded helm, and ask about cast sheet. If your boat is not on file, sending the old shield in is the best deal on the site. If you need it next month, or you want someone to walk you through it, pay a regional plastics shop more. And for a flat console shield you can measure yourself, Boat Outfitters will cut one, or our boat window roundup covers doing it from sheet.
