Oct 11, 2009 The Compac 19 is a very capable and seaworthy sailboat designed by Navel Architect Bob Johnson, who designs the Island Packets. The Compac 19 has a B/D ratio of.40, meaning the 800# keel is 40% of the total displacement of 2,000#. She's a very stable sailboat because of the B/D ratio and the flat hull design.

Boat Displacement Speed Calculation
The below given is the online Hull speed calculator which you can use it for the boat displacement speed calculation with ease. Just enter the boat's waterline length to get the result.
Formula:
H = 1.34 × √(L)M = H × 1.1508N = H × 1.852Where,H = Hull Speed in KnotsM = Hull Speed in Miles/Hr N = Hull Speed in Kilometers/Hr L = Boat's Waterline LengthHull Speed: It is otherwise called as displacement speed is the speed at which the wavelength of the bow wave (wave formed at the bow of the ship or boat, when it travels in water) is equal to the length of the boat. As the speed of boat increases from rest state, the bow wave's wavelength increases, and usually its crest-to-trough dimension (height) increases as well.
Boat Displacement Speed Calculation: Make use of this simple online hull speed calculator to calculate the boat displacement hull speed with ease. Also, you can refer the below-given example problem to understand the displacement hull speed calculation on your own.
Example
Hull Speed
Calculate the hull speed, if the boat's waterline length is 12 feet.
h = 1.34 * √(12)
= 1.34 * 3.46
h = 4.64
Hence the hull speed is 4.64 knots.

This is the current up-to-date list of the U.S Coast Guard's minimum safety requirements for recreational boats with sizes of up to 65 ft (19.8m) in size. These requirements detail what boating safety equipment must be present on board, and other necessary features that must be installed to comply with federal laws.
It's worth noting that these are only the minimum requirements, and we recommend that you exceed them if you can. Similarly, these USCG rules are only the federal requirements. Individual states may have additions to this list, with additional equipment and operating standards require on top of these minimum requirements. Check with your local authorities to find out the specifics.
U.S. COAST GUARD MINIMUM REQUIREMENTS FOR RECREATIONAL BOATS
Recompress 19 10 28 Sailboat Trailers
Personal Flotation Devices
For boats smaller than 16 ft (4.9m): One approved Type I, II, III or V (must be worn) PFD for each person on board or being towed on water skis, tubes, etc.
For boats sized between than 16 ft and 65.6 ft (20m): One approved Type I, II or III PFD for each person on board or being towed on water skis, etc.; and one throwable Type IV device. Translate tab 2 0 8 km. ( A type V PFD may be used in lieu of any wearable PFD if approved for the activity in which the boat is being used. A TYPE V HYBRID MUST be worn to be legal.)
Note: Check state laws for PFD wearing requirements for children and for certain water craft and sports. Federal Regulations mandate that states without child life jacket laws require that youths under 13 wear an approved PFD whenever a recreational boat is underway, unless below decks or in a closed cabin. States with existing regulations are not required to alter their status. Make sure you check your state regulations before getting underway with children onboard.
Bells and Whistles
For all boats smaller than 65.6 ft (20m): Every vessel less than 65.6 ft. (20 meters) in length must carry an efficient sound producing device.
For boats larger than 65.6 ft: On Federally controlled waters, every vessel 65.6 ft. (20 meters) or larger in length must carry a whistle and a bell. They must be audible for 1 nautical mile.
Visual Distress Signals
These visual distress signal requirements only apply for coastal waters, the Great Lakes and U.S. owned boats on the high seas.
For boats smaller than 16 ft (4.9m): They are required to carry approved visual distress signals for night-time use.
For boats above 16 ft but no greater than 65.6 ft: They must carry approved visual distress signals for both daytime and night-time use.
Fire Extinguishers
For boats up to 26 ft (7.9m): One B-I type approved hand portable fire extinguisher. (Not required on outboard motorboats less than 26 ft in length if the construction of the motorboat is such that it does not permit the entrapment of explosive or flammable gases or vapors, and if fuel tanks are not permanently installed.)
For boats between 26 ft and 40 ft (12.2m): Two B-I type OR one B-II type approved portable fire extinguishers.
For boats between 40 ft and 65.6 ft: Three B-I type OR one B-I type PLUS one B-II type approved portable fire extinguishers are required.
Note: When a fixed fire extinguishing system is installed in machinery spaces it will replace one B-I portable fire extinguisher.
Ventilation
Coast Guard requirements on ventilation differ depending on the date your boat was manufactured. The requirements don't change depending on the size of your vessel, just the date it was built. Acorn 6 0 3 – bitmap image editor.
Boats built on or after 8/1/1980: At least two ventilation ducts capable of efficiently ventilating every closed compartment that contains a gasoline engine and/or tank, except those having permanently installed tanks that vent outside of the boat and which contain no unprotected electrical devices.
Engine compartments containing a gasoline engine with a cranking motor are additionally required to contain power operated exhaust blowers that can be controlled from the instrument panel.
Boats built before 8/1/1980: At least two ventilation ducts fitted with cowls (or their equivalent) for the purpose of efficiently and properly ventilating the bilges of every closed engine and fuel tank compartment using gasoline as fuel or other fuels having a flashpoint of 110 degrees or less. This applies to boats constructed or decked over after April 25, 1940.
Back Fire Flame Arrestor
One approved device on each carburetor of all gasoline engines installed after April 25, 1940, except for outboard motors. This regulation applies to all recreational boats.
Navigation Rulebooks
All boats over 40 ft in length must carry an up to date copy of the ISDOT ISCG International – Inland Navigational Rules book on board.
Other Things To Consider
It's worth noting that some states have requirements in addition to the federal requirements. Make sure that you check your state's boating laws for additional requirements. While these aren't always mandatory, we've put together a short list of things that are essential to keep aboard, no matter what size your boat is.

Other Things To Consider
It's worth noting that some states have requirements in addition to the federal requirements. Make sure that you check your state's boating laws for additional requirements. While these aren't always mandatory, we've put together a short list of things that are essential to keep aboard, no matter what size your boat is.
First Aid Kit
A first aid kit should be kept on board. Make sure it has a selection of band aids and bandages, as well as range of medication.
Tools
Keeping tools on your boat can help you out in a bind. Don't rely on pocket knives and multi-tools; having the right tool for the job will make minor repairs much easier.
VHF Radio
No boat should leave the marina without some kind of practical communication device. While some boaters are confident enough to leave with just a cell phone, a portable VHF radio will be of far more use in an emergency.
Emergency Fuel And Water
Spare fuel is sensible to have on board. You don't want to get caught out with an empty fuel tank. Similarly, extra reserves of drinking water should also be kept aboard. Adware zap pro 2 7 0 0.
Bilge Pump
While most large vessels will have bilge pumps as standard, we recommend traveling with a manual bilge pump to help bail out water in the event of a power failure. A bucket will also work, but a dedicated bilge pump is a better tool for the job.
Sun Protection
A bottle of sunscreen should be kept along with your first aid kit. There will be at least one occasion when you head out on the water but forget to bring some sun protection.
An Anchor
An anchor and chain may help in an emergency. If you can keep yourself anchored to a single point, it will be easier for authorities to find you. An anchor with enough chain should be kept aboard all recreational boats.
In Summary: USCG'S Required Boat Safety Kit
The U.S Coast Guard's minimum requirements are just that: the minimum requirement. We recommend that you exceed these requirements where possible. There's nothing wrong with carrying more PFDs than you need, or equipping more visual distress signals than the rule book says.
Don't forget, these Coast Guard boat requirements are in place to keep you safe. Besides, if you don't follow the rules and end up having an accident, your insurance company won't pay you a dime if you didn't take the necessary precautions.
