Non-Skid Tapes for Boats

Durability and grip in non-skid tapes.


Slips and falls will probably always be the greatest hazard on a sailboat, whether the result is a trip over the side, a knee slammed into the deckhouse, or a tumble down the companionway.

In previous reports, Practical Sailor has reviewed paints and glue-on mats for restoring large areas of decks. Weve also looked at ways to make your own non-skid varnish (see Finishing the Cabin Sole, PS Advisor, PS July 2015) but what about those areas that you need to fix right away? Wouldnt textured non-skid tape, or grit-infused tape sold at the chandlery or hardware store serve well?

In fact, there is a place for the simplicity of adhesive tapes, since many new boat owners are reluctant to start prepping for paint when only a few small areas require improvement.

Vinyl Non-Skid Tape

Our test boat had several areas around the deck hatches with slick spots that lacked textured gelcoat. Textured vinyl tape was a permanent solution.

The hatches themselves are slick as well, but we chose not to add grip tape there. Encouraging regular use as a walking surface seemed like a bad idea. (Why dont chandleries carry no-step stickers?) We found the same grip tape to be handy for several applications in the cabin, dock, and cockpit.

Another valuable application has been deck protection.

Chain guard. Every time the anchor is hauled, the chain grinds across the deck before the windlass. The prior owner avoided damage by keeping a towel under the chain and by staying in marinas.

Our solution was a layer of vinyl tape, which endured about 400 anchoring cycles before showing noticeable wear. Yes, we could have glued a permanent guard, but an easily reversible fix is often a smart way to solve new problems, especially when the boat is new to you. A decade later it took only five minutes to replace.

Scuffs. Winch handles are constantly leaving black stripes in the cockpit, as knees and hips slam them into the gelcoat. A nearly invisible pad of tape lasts more than a decade.

The best brand? Weve used Life Safe and Seafit textured vinyl, and occasionally use hardware store brands. We never noticed a big difference in wear, although the Seafit seemed to adhere better over the course of time.

Media-Coated Grip Tape

Although the non-skid on the deck was grippy enough, the edges of steps and a few steep areas needed improvement. Vinyl tape was of little use in these places, since it offers no better grip than the existing textured gelcoat.

Yes, you can lose some skin if you slide on grip tape, but a scrape is far better than slipping and falling. If you do slide, because the course grit media is cutting into the sole of your shoe, the loss of traction is not as sudden and complete as it is with textured gelcoat. You slide at a controlled rate, rather than instantly slipping loose. Grip tape is used on skateboards for this reason.

Steep areas. A few slopes on the sides of the cabin are in the 30-45 degree range; just shallow enough to invite the occasional misstep, yet steep enough that without non-skid a misstep would result and a sudden, and potentially serious fall. On the test boat these areas were finished in black gelcoat. We neatly overlaid them with black grit-infused tape. Problem solved.

Step Edges. For aesthetic reasons, the non-skid pattern often ends an inch or more from the edge of the step, and the edge of the step is the first place to wear slick. You can match the white gelcoat with white grip tape, but a contrasting color tape makes the edge of the step more visible. We covered all of our white steps, inside and out, with contrasting black abrasive tape.

A common complaint about grit-infused tape is that it is uncomfortable for bare feet. There are varying levels of courseness available, and you can find the one that best suits your comfort and needs. We tested the fine to medium grits and felt no discomfort with bare feet. Tapes recommended for swimming pool steps are usually kind to bare feet.

The best brand? We used 3M Safety Walk on the test boat and a house brand (Uline) of abrasive tape on a sister boat. The Uline tape shed more grit, although it still held up for years. We also have used both brands in industrial settings. But because of its durability, the 3M Safety Walk is our Best Choice.

Ease of replacement is quite reasonable, as long as you remove the tape within 10 years, before the adhesive turns hard. We have just replaced many of these patches, ranging from 8-10 years old, and all remained in functional condition.

Those sections that see light traffic may have another decade remaining.

Certainly there are more durable options out there, but they are not easy for the DIY sailor. In our view, self-adhesive non-skid tape is a winner for small problem areas.
