Living at Sea - My goal of living upon the oceans
Special Focus:HIGH SEAS SECURITY
by Frank Camper
Just as carjackers roam the highways in search of easy victims, so pirates roam the seas, killing passengers and crew before making off with the loot or the boat itself. This book shows how to protect your vessel, passengers and crew from a variety of real threats. Subjects covered include: Preparing for sea-borne defense; Alarms; Weapons; Flares; And much more, including sources for the items covered. The author has worked with U.S., Mexican and Saudi Arabian forces in the Gulf of Mexico, the Caribbean, and the Red Sea.

GULLIVER: a voyaging powerboat
World-traveling cruising Cat
VOYAGER was a direct out growth of an earlier design for Allan & Brenda Guenter, which at 50' was the largest catamaran we had attempted up to that time. Having seen Allan use a 3-axis milling machine at IMD in St. Johns, NF, to mill the molds for a 50' cat, when the opportunity to create this design came we didn't hold anything back, even the most complicated shapes were now easily achievable. As the name implies, we stole the general pod configuration from Startrek Voyager and adapted it to the requirements laid out by the customer, but as any designer will tell you, that is only the starting point, after that the designer adds everything that he wants also !!!!!!!. http://members.aol.com/advtransys/private/voyager.htm

Power-Vent Surface Drive Technology
The power vent system lets exhaust gases and outside air flow directly at the propellers and makes thereby fast gliders still stronger.
Particularly formed ventilation holes in the side panels of the boxlike construction give its name to the power vent system. The initiated engine exhaust gases and outside air sucked in by injector effect are led by the exactly calculated holes of the box into the area of the propellers. The direct ventilation reduces flow resistance in the wake of the propellers. In practice Don Smiths 8 tons heavy 4èr thereby came clearly faster into sliding travel and could increase its maximum speed by considerable 32 % from 33 kn to 44 kn. Section-dipped drive systems, like the Surface drive of Howard Arneson led in theory and practice to quite new realizations how one moves a ship fast by the water. With surfaces (Surface) drive only the propellers have and the Skeg contact with the water, reduce the Stroemumgswiderstand, make fast and save sprit in sliding travel. The drives installed at the tail are easy to install and have fewer depth than the conventional drives with reversing gearing, inserted under the boat soil, which is inclined nevertheless rather to the cavitation as at the Oberflaecher ventilating Surface drives. Beyond that surface drives have the advantage that they can be raised and lowered while driving like a Z-drive. Thus one reduces depth and Stroemumgswiderstand and always brings the boat (almost) into the optimal swimming position.
Mark of Small, owners of one in Florida resident engineer and Enwicklungsfirma, still refined the successful concept of the surface drives with its ultramodern drive system. With its power vent it does not however only concern an easy advancement. Powerboat enthusiasts believe rather firmly in the fact that with Smalls drives a type revolution occurred. At least in the world of the speedboats.
However want opinions, which cause sport boat drivers to thinking about it, whether the performance gain of the part-dipped drives counts itself at all, do not grow silent. Critics are afraid additional maintenance costs of the complicated mechanics, the hurting barness of the drive unit hanging on the tail and the long acclimatizing time, which are needed for perfect trims of the drives under constantly changing weather conditions and rates.
Smalls power vent system does not only want to solve these problems, but to offer still additional advantages beyond that. But we regard first the system.
Power vent system: nothing new
Professor Dr. Hartmut Brandt commentates
The ventilation been made with the part-dipped propeller from the free liquid surface and with the full-moistened drive, like in the available case, by appropriate channels. This method of the artificial ventilation is a well-known measure for the avoidance of cavitation. Waves, wellenboecke and the bosses contribute substantially to the resistance. These resistance proportions omitted with the conventional part-dipped propeller and are at least reduced with the power vent system by the forced ventilation. Thus a speed increase in the comparison with the normal drive is enabled ". Likewise it is conceivable that with accelerating by the adjustment of the air supply the proportion of the ventilation on the wing areas can be controlled. It is unfavorable with the part-dipped propeller that only the dipped wing area contributes to the thrust. Here the full-moistened forced-draught propeller is superior. It is just as correct that by the ventilation noises are absorbed. Thus does the power vent system have only advantages? That is not like that. If soil structure and appendices are included into the overall efficiency, the propeller freely part-dipped behind the mirror has a slighter resistance. A disadvantage during restrictor travel. Here a substantial additional resistance is to be overcome by the unfavorable soil structure and the wasserzulauf the propeller.
Complicated change
The power vent system is fixed constituent of the trunk construction. Honest way must point out one clearly that it cannot be inserted during a nachruestung without extensive changes at the trunk. If one decides, a boat with this system to out or re-tool, the rear fuselage end section is modified in such a way that a particularly designed boxlike structure within the soil area of the V develops ". Double engines are used installed as, and installed the propellers onto solid waves under the trunk. The side panels of the boxlike construction have particularly formed ventilation holes, which give its name to the power vent system.
If the boat moves by the water, the initiated engine exhaust gases flow for the front end of the box, while in the rear end of the box by the using Injectorwirkung air is sucked in. The water, which occurs the holes at the pages of the box with high rate, produces negative pressure, whereby outside air and exhaust gases are led by the particularly developed holes of the box into the propeller area. Since air tries natural to rise upward the water is ventilated around the propellers. The quantity of the application of pressure, i.e., the vertical admission surface is limited by the above trunk and by the amount of air flowing by the ventilationsoeffnungen of the box. The direct ventilation reduces flow resistance in the wake of the propeller. Size and form of the openings adjust the ventilation. The promised adjustment of the height of level of the unbeluefteten water at the propellers is surely not possible however. Everything else perfectly, becomes nevertheless faster the boat fits.
Smalls power vent system is contrary to the complex mechanical surface drives a passive system without mobile sections. Although calculating size, form and arrangement of the ventilation openings is a complicated affair, the technical concept is a rather simple and elegant solution. Whether also in practice functions, should show roughly.
Don Smith, former offshore world champion, installed the new system at its built high speed boat.Fewer depth
Smiths'12,62 m long 4èr weighs 8 tons. With two 350 HP strong Yanmar diesel engines and conventionally immersed propellers brought it the boat on a top speed of 33 kn. The same boat was fast after the modifications in the trunk construction and the installation of the power vent system with the same 6-Zylindermotoren 44 kn. For the 32%igen rate increase the 20 " x 27 " large five-wing propeller of Nibral were jointly responsible. Higher rate is not according to Smith the only advantage power vent. The noise level is reduced by the exhaust which is under water clearly and the engines with critical changes of direction and with small running speeds is loaded evenly. Thus those comes scarcely 10 t heavy Smith 42 with somewhat already more than 12 nodes into sliding, and achieves from the deadlock accelerated in a little more than 12 seconds of sliding travel with 22 kn.
The depth amounts to then times evenly 0.60 m. counts one in l/sm moves owing to the high rates also the fuel consumption of two 350 HP strong Yanmar engines on moderate level. 2.8 is moderate l/sm with 3100/min and 37 kn cruise speed. With full power with 3400/min and 44 nodes the two Japanese self fuzes consume together 3.1 l/sm.
The man to control needs, in order to achieve the optimal efficiency to not constantly adjust the angle of incidence of the drive units. The propeller trim is fixed adjusted and the amount of air by the ventilation soeffnungen automatically regulated. Thus the power vent system can be served more easily.
