Stern — transom that is ploskosrezannym. Made of sheet of aluminum of 1 mm thickness and redstavleny in the upper part of pine Board with twenty 125 mm wide. Here note that in order to raise outboard motor up higher above the water, the top edge of the transom Board made convex. However, the same was made convex and the upper edge of the Board extension of the bulkhead, but with a different goal — to give the deck bulge to hit her, the water flowed over the side and into the cockpit. In the middle of the transom Board put on the fittings of the steel plate thickness of 1 mm to a mounting bracket of the motor is not damaged the Board.
Although the boat is a double, but the seat (the Bank) one and installed it as usual — across boats, and along it in the middle and slightly obliquely. This arrangement banks are not only much more comfortable for fishing, but allows the helmsman and passenger to occupy any location in the cockpit depending on the congestion of boats and rough water, and if necessary to change places right on the water and even on the go boat risk-free to flip it or fall overboard myself. Accommodation in the boat of the fuel tank capacity of 5 liters, boxes for fishing tackle, drawer under clothes organized, if possible, so that the bottom Ostap almost completely free, that has improved operating conditions and habitability (if that word can be used for small area and open to all the winds of the cockpit).
Big and concentrated, the load on the bottom of the boat passes installed vraspor stand-pippers seat banks. Therefore, the lower end of the strut rests on the washer rather large diameter of duralumin sheet, 3 mm thick Washer placed at the bottom and riveted to the bottom of single rivet with a diameter of 10 mm. and. locking head made in the form of a peg, which is the locking position of the lower end of the tubular rack.
The wooden parts before assembling impregnated with hot linseed oil. Duralumin parts before painting are cleaned by the oxide film (at the same time, given the roughness of their surfaces for better grip), are degreased and primed. The entire boat after assembling its parts into a single structure will be painted with enamel.
Forepeak bale will not be sealed. Therefore, unsinkable boats provide placed in 20 plastic bottles with a capacity of 1.5 l and two cans of 10 l. mounted on the underbody in the aft cockpit of the boat and attached as tank, clamps to the transom.
Vespa tried to make durable, light. comfortable and unsinkable. Represent their design.
The spindle of the paddle is made of duralumin tubes with a diameter of 32 mm and millimeter wall thickness. In the place of connection of the oarlocks spindle increases from the inside cut thick-walled aluminum pipe with a wooden plug, fastened in there with epoxy glue Tube is required to prevent the ingress of water and paddle to the axle-bolt oarlocks not as intense smash a hole in the spindle. Also, to increase wear resistance on the axle between the fork horns of the oarlock and tube Val on both sides of the inserted Teflon washers.
1 — stick (birch); 2 — spindle (tube 32×1): 3 — tube (fir); 4 — amp (tube aluminum Ø30×3); 5 — bracket (pipe aluminum Ø32×4); 6 — rivet (aluminium Ø6, 3 pieces); 7 — blade (made of anodized aluminum, the sheet s2,5)
1 — bushing for pin (steel pipe Ø15×2,25); 2 — panel (steel sheet s2, 2 PC.)
Rowlocks and collection (parts of paddle POS. 5, 6 and 7 are shown conventionally in cross section):
1 — pin (steel 35, round Ø10); 2 — plug (steel 20, strip 20×3); 3 — axis paddle (М6х55 bolt with nut); 4 — gasket (PTFE washer, s2); 5 — spindle paddle: 6 — amplifier; 7 — tube
Revision anti-cavitation agent alocrom plate on the outboard motor “Veterok-8M”
To get the oars are made of sheet aluminum of medium hardness with a thickness of 2.5 mm Along the blade, by bending the stream. Attaching it to the spindle is made not directly but through a transient insert — amplifier root portion of a spindle made of thick-walled aluminum tubes of an external diameter of 32 mm. also with cork. To be able to insert the amplifier in the spindle, one end of the first protochen to the inner diameter of the second. At the other end made the slot for the blade, the end flattened and riveted details. The amplifier is planted in the spindle on epoxy glue. For the strength of the joint in glue, you can add clean small metal filings or aluminum powder.
It is possible to manufacture the spindle oars of fir. In this case its diameter, and thus the distance between the oarlock horns of the fork should be increased in 1.5 times.
The mass of the boat does not even reach 20 kg, but the displacement (total weight of passengers and payload) was about 130 kg.
The boat is equipped with a modified outboard motor “Breeze” with 8 HP (went under the 12-strong). It is important that the penetration shaft of the motor. I have the motor lifted, and to prevent air suction plate anti-cavitation agent widened at the bow and sides to her bottom riveted plate. The planing depth of the screw is about 250 mm, which is sufficient grass and debris floating on the water, until the screw can’t reach.
Yet outboard engine Veterok dismantled the emphasis, and to the rear Board at the bottom of the boat riveted dural area with a block of hard rubber. This suspension of the motor not only dampens the vibration and shock but also reduces the load on the transom. From the latter point the motor mount is in the raised position also dismantled and the engine is now in this position rests on the left side and no stops.
Speed boat with motor “Veterok-8M” 8 HP — 30 km/h, and with 12-horsepower motor — up to 40 km/h.
One driver even under 8-horsepower engine the boat is easily out and on Glossary mode, and under engine capacity of 12 HP, her hull almost completely out of the water. Further riding in economical gliserna mode (fuel consumption) for the motor.
It is seen that in the presence of the water ripple speed to run the boat on plane increases. Happy voyage to you or. as sailors say: seven feet under the keel. Just remember to wear your life vests even if you can swim well
