Polyethylene Spar Buoys: SP 10/60 Regulatory, Can and Nun Markers
Made on the Gulf Coast | In business since 1999
The SP 10/60 is a polyethylene spar buoy from Wet Tech Energy, in business since 1999. One 10 in x 60 in hull, with a 0.25 in wall, is filled with 2 lb closed-cell foam and takes an interchangeable can or nun top. Use it as a spar regulatory buoy (white with orange bands and your message), a green can for the port side of a channel, or a red nun for the starboard side — on lakes, reservoirs, marinas, rivers, no-wake zones, swim areas, and shallow-water channel marking.
These are foam spar buoys, not hollow: every SP 10/60 is filled with 2 lb closed-cell foam. Made on the Gulf Coast.

Why choose our foam-filled spar buoys
- Polyethylene hull with a 0.25 in wall
- One mold, two tops: flat can top or cone nun top
- Filled with 2 lb closed-cell foam
- Rides 36 in out of the water with about 24 in draft, made for shallow water
- Bottom pad eye with a 1 in hole sized for a 3-ton shackle or swivel
- Made on the Gulf Coast
A polyethylene spar buoy will not rust and is easier to set and pull from a small boat than a larger steel navigation buoy. For lakes, marinas, and shallow water, the SP 10/60 is the spar in our polyethylene marker line; see also the M-711LP 700 mm inland water buoy. For open water and larger markers, see our navigational buoys. For the rest of the polyethylene line, see shallow water polyethylene buoys.

Spar regulatory buoys, can buoys, and nun buoys
The same SP 10/60 spar buoy covers three common jobs:
- Spar regulatory buoys: white with orange bands and your message, such as Slow No Wake, controlled area, or DANGER KEEP OUT.
- Can buoys: green with a flat top to mark the port side of a channel.
- Nun buoys: red with a cone top to mark the starboard side of a channel.
See our slow no wake buoys and our full line of regulatory buoys. For a larger polyethylene regulatory or hazard marker, see the 711 buoy (M-711LP).

Spar buoys for lakes and shallow water
With about 24 in of draft, these spar buoys are built for water where larger navigation buoys will not fit. Typical uses:
- Lakes and reservoirs
- Marinas
- Rivers
- Shallow water
- No-wake zones
- Swim areas
- Channel marking
Planning a whole lake? See our lake buoys and barrier floats. Need a bigger polyethylene marker that can carry a light? See the 711 buoy, our 700 mm marker buoy. Custom sizes and graphics are built in our shop; see custom buoys.
Anchors, chain, and lights
Order your spar buoys ready to set. We provide anchors, chain, shackles, and custom mooring system solutions sized for your site, plus USCG/IALA compliant LED marine lights from all major brands, fitted to your Wet Tech-built buoys. Our crews can also install them. Wet Tech Energy has installed buoys since 1999.
Sizes and replacements: spar, can, and nun buoys
Replacing worn or faded spar buoys, can buoys, or nun buoys? Our standard SP 10/60 spar buoy is 10 in x 60 in, rides about 36 in out of the water with about 24 in draft, and takes a flat can top or a cone nun top on the same hull. The bottom pad eye has a 1 in hole sized for a 3-ton shackle or swivel, so it can go back on a typical shackle-and-chain mooring.
Need a different size to match buoys already on your lake? We are a custom shop: send us the dimensions, color, and message of your existing buoys and we will build to your spec. Request a quote or call 337-893-9992.

Frequently Asked Questions
What is a spar regulatory buoy?
A spar regulatory buoy is the same SP 10/60 polyethylene spar buoy, finished white with orange bands and your message — for example Slow No Wake, controlled area, or DANGER KEEP OUT. It uses the same 10 in x 60 in foam-filled hull as our can and nun spar buoys. See also our regulatory buoys.
What is the difference between a can buoy and a nun buoy?
A can buoy has a flat top and a nun buoy has a cone top. Green cans mark the port side of a channel and red nuns mark the starboard side. Our spar buoy uses one mold with an interchangeable can or nun top, so you get the same hull either way.
How much of the spar buoy shows above the water?
The buoy is 10 inches in diameter and 60 inches long. It rides about 36 inches out of the water with a draft of about 24 inches, which makes it a good fit for lakes and shallow water.
Is the spar buoy foam filled?
Yes. The SP 10/60 spar buoy is filled with 2 lb closed-cell foam.
What are your spar buoys made of, and how thick is the wall?
Polyethylene with a 0.25 in wall, filled with 2 lb closed-cell foam. Made on the Gulf Coast.
What shackle should I use on the pad eye?
The bottom pad eye has a 1 inch hole sized for a 3-ton shackle or swivel. We recommend a 5/8 inch bolt type anchor shackle with a 3/4 inch pin. That shackle is rated at a working load limit of 7,165 lb; this is the shackle's own rating, not a rating for the buoy.
Can I add a light or custom graphics?
Yes. We can fit a USCG/IALA compliant LED light from any major brand on top of the buoy, reflective bands, and custom graphics such as Slow No Wake or controlled area messages.
Do you supply anchors and chain?
Yes. We provide anchors, chain, and custom mooring system solutions sized for your site, so you can order a complete mooring with your buoys.
Where are your spar buoys made?
Made on the Gulf Coast. Wet Tech Energy finishes each buoy to your specs at our shop in Maurice, Louisiana, and has been in business since 1999.
How fast can you ship?
Call us for lead time at 337-893-9992, or request a quote. We ship from our shop in Maurice, Louisiana across Louisiana, Texas, Mississippi, and the Southeast.
Do you install buoys and moorings?
Yes. Wet Tech Energy has installed buoys since 1999. We supply the buoys, anchors, chain, and lights, and set them on station for you.
Do you make a larger polyethylene marker buoy?
Yes. For a bigger polyethylene marker, see the 711 buoy (M-711LP), our 700 mm inland water buoy. The SP 10/60 remains the spar in that line. Other polyethylene products are on our shallow water polyethylene buoys page.
