Bird Control...When You Open Your Boat for Summer

So you're about to open your boat for the summer. You look up and see gulls circling, just waiting to plop a few choice deposits on your clean deck and shiny polished railings. It's bad enough you have to clean pounds of poop off your canvas covers, but now you'll have to worry about bird droppings all over your antenna and radar gear, windows and portholes, sheets and cleats. Without effective bird control measures, your boat's as vulnerable as a bait shack.

 

You know from experience that seagulls, cormorants, and pigeons enjoy perching on masts, spreaders and canvases. You also learned that the high concentration of uric acid-- found to be even higher in sea birds--could discolor paint, stain canvases and eventually erode steel. And who can ignore the health risks of bacteria and parasites that live and grow in bird droppings? They can carry any of 60 known diseases. Bird control is an investment that will save you time, money and a lot of aggravation.

 

Lucky for you, there are all sorts of effective bird control products for boats. All are easy to install and basically maintenance free. Here are just a few you might look into to protect you boat.

 

Bird Spiders

 

Ideal for use on decks, rooftops, and other flat surfaces, bird spiders have stainless steel "arms" that whip around in the breeze to keep pest birds from landing. Spiders come in various sizes--usually 2-, 4-, 6- and 8-foot diameter arm lengths to cover large areas and deter a wide variety of birds. An effective bird control device against pigeons, seagulls, and larger birds, spiders have no moving parts to wear out.

 

The best bird spiders have a U.V.-protected polycarbonate base. One manufacturer's bird spider comes pre-assembled and ready to place or mount. Most spiders come standard with a glue-on base, so they can be glued down to most surfaces. You can also get spiders with railing mounts for easy attachment to boat rails. Other attachments include a removable sand bag base that allows spiders to be used on boat canvas and Biminis, and a variety of optional boat bases that allow the spider to be used on masts and radar units. As a bird control device, bird spiders are ideal for use in areas where large flocks of pest birds have become a particularly irksome.

 

Solar Powered Bird Repellers

What a novel idea: use the sun's power to whisk away pest birds. Solar powered bird repellers have long blades that whip around to discourage seagulls, pigeons, and crows from landing on your boat. Some repellers even have adjustable "arms" that cover up to 5 feet in diameter and turn continuously at 30 RPM. Better systems can store the sun's converted electrical energy and tap into it to turn the repeller's arms throughout the night or during overcast days. And yes, bird repellers are harmless to birds.

 

Bird Spikes

Usedby boat owners and marina facilities managers around the globe. Bird spikes are highly effective bird control devices for use against pigeons, seagulls and larger birds. They can keep these pests from landing on masts, towers and other areas of a vessel. You can get them in either rigid U.V.-resistant unbreakable polycarbonate or high strength, durable stainless steel. The spikes look like a porcupine on steroids, but they're harmless to birds and people. In fact, bird spikes have been approved by a number of humane groups worldwide--including the U.S. Humane Society and PICAS (Pigeon Control Advisory Service).

 

Stainless steel spikes typically come in 3-, 5- and 8-inch widths, and their non-reflective metal finish makes them virtually invisible when installed. Bird spikes even come in a variety of colors--including white, tan, gray, black, brown, brick red and crystal clear.  The plastic spikes come in 3-, 5- and 7-inch widths and are ideal for use on masts and radar units because there are no EM interference problems with plastic. One manufacturer even sells a no-gap spike that's easy to mount on curved surfaces.

 

Banners, FlashTape, Balloons

 

Birds of any kind don't really like to be around bright flapping things that whip around in the wind. Which is why bird scare devices are so effective when it comes to bird control on boats. They annoy and frighten many types of birds by creating an "Optical Distraction Zone."

 

Take iridescent reflective foil or flash tape, for example.  It's not only inexpensive to buy but easy to attach to just about any part of your boat. String it up on masts and near radar units and birds will be too nervous to land. Another effective visual scare device, the inflatable balloon is ideal for use on masts, radar antennas and overhangs. Balloons intimidate pest birds with their lifelike reflective predator eyes and markings. Teardrop shaped scare-eye diverters are just as effective. They're easy to hang in problem areas. Some bird scare devices have iridescent foil eyes to frighten birds by day and glow-in-the-dark backsides to keep them away at night.

 

When installing bird scare devices, keep in mind that most birds prefer to land on the high points of a vessel, so be sure to mount these deterrents as high as possible.

Essential Boat Radar $15.4 From the basic principles through to more in-depth expertise, Essential Boat Radar is your no-nonsense introduction to radar. It guides you into the subject by providing sufficient information to understand what's going on, proceeding directly with basic radar use. Bill Johnson clearly explains what radar is, outlining what is does and doesn't do. He describes how to make simple adjustments to get a decent picture, and explores how to use the basic radar. This is followed by greater information on the various confusions and anomalies that the picture can present, progressing to the more complex functionality of a modern digital (raster) set. Finally, you learn the key elements to consider when choosing a radar system for your boat, and also how to install it. Essential Boat Radar includes: full explanation of what radar does, and how it does it how to use radar for collision avoidance, with reference to the relevant COLREGS how to use radar for navigation and pilotage practical exercises for using radar detail on related subjects, such as: AIS, radar reflectors guidance on choosing and installing radar systems

Radar Companion $3.95 These splashproof cards take the mystery out of using radar on a small boat for navigation and collision avoidance. A radar screen in the cockpit is the most useful tool for navigation. It can show you the land and approaching boats in daylight, in darkness and in fog. And, combined with GPS, it can show you your position and destination relative to the land as a 'birds eye view'. Pat Manley concentrates on using the controls to get the best picture, then explains how to understand the display and gives plenty of examples of radar plots.

Radar for Mariners $15.19 Become an Expert Small-Craft Radar Operator Nothing beats radar for guiding your boat through the darkest night or the thickest fog. Radar enables you to plot a fix from just a single buoy or landmark, and it is the only navigation tool that tells you not just where you are, but who else or what else is out there with you. Today's smaller, affordable, more powerful radars make more sense than ever for sailors and powerboaters. This complete, in-depth manual shows you how to: Choose the best radar model for your sail- or powerboat Install, adjust, and operate your system Interpret the images on your radar screen Pilot your boat and track the movements of vessels around you Use radar to track and avoid squalls, to outmaneuver competitors in a yacht race, and for other specialized tasks Interface your radar with a digital compass, GPS, or electronic chart "Radar for Mariners" comes with a Radar Resources CD-ROM that includes a "field guide" to screen and target images, plotting sheets for printing, an e-book copy of the complete "Navigation Rules," sample radar manuals, and more. It also includes a free trial version (30-day period) of the Starpath Radar Trainer simulator, plus an encrypted copy of the Full Radar Trainer you can purchase at a discount nearly equal to the price of this book (See the enclosed CD-ROM for details.) Praise for David Burch's "Emergency Navigation: " "A standout from the otherwise faceless navigation texts that pass through our offices. Anyone venturing offshore should read this book thoroughly."--"Yachting" Praise for David Burch's Radar Trainer navigation program: "The Starpath Radar Trainer course is excellent It is comprehensive and thorough . . . I would not hesitate to recommend it. . . . Any skipper can profit by using this course."--Elbert S. "Mack" Maloney, author of "Chapman Piloting & Seamanship"

The Adlard Coles Book of Radar $25.38 Radar is notoriously tricky to operate and 'read' correctly for collision avoidance either with the land or with other vessels. But used by an informed operator it is an immensely valuable navigation tool - especially in poor visibility. GPS will tell you where you are, but it won't tell you if there's another boat in that spot Rather than taking a theoretical, academic approach, this book is highly practical and hands on - complementing the radar owner's manual and explaining what the operator really needs to know when faced with actual situations at sea. Packed with illustrative photos, charts and radar screen shots, this book gives guidance from a real life, on-the-water perspective, and will enable readers to solve problems immediately.
