VARYING TYPES OF MARINE SURVEYS

Posted On: February 27, 2019

There are different types of marine survey. 

“One is a Pre-Purchase inspection, which is the most extensive.

The Condition & Valuation inspection, which is the one most requested, is mainly used for financial and insurance purposes. Specifically, it’s very useful to insurance companies to determine if the vessel is an acceptable insurance risk. It will also include the valuation to determine the fair market value of the boat.

The Damage inspection consists of an inspection that will help establish the cause of a loss and settle on the extent of the damage.”

It’s a good idea to ask a surveyor if they are familiar with the type of boat to be surveyed.

Some surveyors may only survey modern boats typically used in charter, and may lack the specific knowledge of boats built using unusual materials, or older boats. If a boat is wood, or steel or alloy, then finding a surveyor with experience with these materials is important. Ask them for a sample survey too. Most surveyors will be happy to provide this.”

Prepare the boat for a survey

The boat should always be clean and free of miscellaneous items. Paperwork should be on hand and available to present to the surveyor. If it is required to have the boat hauled out or to undergo a sea trial, the arrangements should be made and scheduled by the owner. 

How long does a survey take?

It depends on the size of the vessel. I can take one full day to inspect a typical 45-foot sail boat. It takes then probably another half-day to write the report. Length of time also depends on the vessel’s overall condition.

A 24-foot runabout can likely have a survey completed in a few hours. A 140-foot mega yacht survey could take a week.

It’s not mandatory for a boat owner or potential buyer to attend a survey. 

The most common question marine surveyors are asked?

How Much? What’s the cost? Owners and buyers all too often look at a survey as merely a logistical ‘hoop’ to jump through. However, a good survey report serves as a tool to highlight deficiencies and plan future maintenance pre-purchase, to determine the cause and scope of damage (particularly if a third party is involved in an incident) as well as study costs for a complete claim and to represent the owner’s interest during the repair process

VHF RADIO GREAT IN AN EMERGENCY

Posted On: February 06, 2019

A VHF Radio Is Best For An Emergency

Fixed-Mount VHF Radios

Arguably one of the most cost-effective safety items you can have on any boat, a fixed-mount VHF allows you to communicate with a wide range of people and organizations: the U.S. Coast Guard, commercial ships, the Rescue 21 network, bridge tenders, TowBoatUS, race committees, and countless others stations. And its full potential is realized when units with Digital Selective Calling, or DSC, are connected to an operational GPS receiver (or have one internally).

While all radios sold in the U.S. over the last decade are equipped with DSC, many operators (the U.S. Coast Guard says about 85 percent) either have not connected their radios to their GPS, nor registered for an MMSI (Marine Mobile Service Identity) number. This is vital for the full functionality of the Rescue 21 system.

Fixed-mount VHF radios are only as good as their antenna systems (a combination of the antenna, coaxial cable, and connections). Antennas should be mounted as high as possible: on the masthead of a sailboat or on the flybridge of a powerboat. Because VHF signals travel more or less in a straight line, a higher antenna will allow a VHF signal to reach more distant stations due to the Earth's curvature.

Common VHF Channels And Their Uses

While VHF radios may have anywhere from 55 to 80 channels, there are relatively few that can be used by recreational boaters. This table lists the most common ones, but because VHF channel use is somewhat geographically specific, a few channels may be different in your home waters. The VHF channels used in Canada and Internationally may have different frequencies and different functions than those used in the U.S.

ChannelSimplex/Duplex*Purpose
*A simplex channel transmits and receives on the same frequency. Duplex channels use different frequencies for transmitting and receiving.
16SimplexInternational distress, safety, and hailing. Monitoring required while underway.
6SimplexIntership safety. Frequently used by towing companies.
22ASimplexU.S. Coast Guard working channel. Referred to as "22 Alpha." Maritime Safety Information Broadcasts are announced on Channel 16, then broadcast on 22A.
21A, 23ASimplexU.S. Coast Guard only. In rare instances, the Coast Guard may ask you to communicate with them on these channels.
9SimplexBoater calling (commercial and noncommercial). Recommended for hailing another vessel (to reduce traffic on Channel 16). Many radios can monitor 16, 9, and a working channel.
13SimplexIntership navigation safety. Ships are required to monitor Channel 13 when at sea. Effective if you are trying to contact a specific vessel in your area, especially if there is risk of collision. Transmissions are limited to 1W to reduce interference.
14SimplexPort operations. In areas with Vessel Traffic Service (VTS), this is the channel they use to communicate with large ship traffic. Can be very helpful for tracking vessels.
24-28, 84-87DuplexPort operations. In areas with Vessel Traffic Service (VTS), this is the channel they use to communicate with large ship traffic. Can be very helpful for tracking vessels.
68, 69, 71, 78ASimplexFor noncommercial communications with other vessels or shore stations. Traffic must be concise. Commonly used by race committees, along with Channel 72.
72SimplexSimilar to previous channels but only for ship-to-ship. No land-based stations can use channel 72.
70SimplexDigital only; used by DSC functions on the radio.
WX 1-9SimplexNOAA weather channels. Local weather is usually on WX1-WX4.



The Invaluable Phonetic Alphabet

To make sure you're clearly understood, especially when using the VHF radio, words often need to be spelled out using what's known as the phonetic alphabet. On a radio transmission, static can produce mistakes. For instance, over the past couple of years, a popular boat name, according to our BoatUS records, has been Blew By You. In audio communications, this can be mistaken for Blue Bayou.

Learn the phonetic alphabet by heart so that you can easily spell out names and words quickly, especially in emergency situations.
