Abstract

A motor boat that can have its key performance characteristics such as fuel efficiency, load carrying, speed, sea keeping ability, number of engines, horizontal stability and lateral stability quickly changed by varying the number of hulls of the boat. A bolted connection method is utilised to quickly add or remove hulls from the motor boat. This connection method uses beams that pass through each hull. At the point of entry into the hull, the hull curves inside and around the beam which is provided with a flexible material such as rubber or foam at these points. Bolts are then passed through the curved in hull and beam, securing the beam in place. Using this connection method the motor boat can be assembled and disassembled quickly. The beams and any smaller hulls can fit inside larger hulls for optimal storage and transportability.

Description

I

New design to change characteristics of powerboat performance Existing Powerhnat A powerboat is any boat that is pmpelled by an inboard or outboard engine.

All existing powerboats boats have fixed hull fbrm that is designed and built with a specific role in mind. No true multi role motor boat exists today, primarily due to the inability to reconfigure the bull itself. If the hull is fixed in terms of length or width then the key parameters of that motorboat (fuel efficiency, load carryin speed, sea keeping abilit>c number of engines, horizontal stabilit>c lateral stability) are fixed as well.

New Design for Powerhoats The desire behind this invention is to create a multi-hull powerboat that can be rapidly re-configured to provide significantly difirent perfonnance characteristics.

The ability to re-configure a power boat hull allows for the emergence of a true multi role power boat. This proposed design is an answer to the need for a new and highly efficient powerboat.

This new design provides for the quick reconfiguring of a multi-hull powerboat via the adding or removing of hulls to have a mono-hull, catamaran or trimaran powerboat.

As a mono-hull powerboat is a powerboat that has a single hull (fig 1, fig 2, fig 3).

As a catamaran powerboat is a powerboat that has two hulls (fig 4, figS, fig 6).

The hulls can be of any length and any width apart. For the purposes of this patent the longer hull (fig 3) is 9m in length and the two smaller hulls (fig 9-i and ii) are each 4m in length. The two smaller hulls (fig -i and ii) can be either identical to each other or minor images of each other.

The longer hull has three connection points (fig -i and ii and iii) of which two or three can be used fur the different hull configurations. Connection points can be added or removed to increase or decrease hull connectivity strength.

The connection method on the longer hull (fig 13) uses horizontal beams (fig 13 -i) that pass throughthe hull(fig 13 -ii)andareboltedinplace(flg 13-iliandiv).Theboltspassthroughthe beams.Thelongerhullcurvesinattheholesforthebeams(fig 13-vandvi / fig 15-iiiandiv) thus the bolts are going tbmugh part of the hut This design also allows for the addition of an optional fixed shelf (fig 13-vii) below the beams on the longer hull, allowing for addition bolts to go through if an engine of significant power output is used.

The connection method on the smaller hulls (fig 14) is to use bolts that pass through the beams (fig 14 -i and ii) to secure the beam on top deck of the smaller hull. The smaller hull deck is reinforced with a metallic sfrip (fig 14 -iii) at the area of bolting.

The beams (fig 9-i, ii and iii / fig 13 -i) are made out of a material of sufficient strength to handle the forces applied to them without breaking.

By reconfiguring the number of hulls of the boat (contact points with the water) one can dramatically change the number of passengers, the cargo weight, sea keeping ability, number of engines, speed, horizontal stability, lateral stability, range and fuel efficiency of the powerboat

Claims

I) A powerboat that can have any or all of its key characteristics of performance (speed, fuel efflcienc)ç cargo weight, sea keeping abffit number of engines, horizontal stability, lateral stability) significantly and quickly changed.
2) A hull connection method that uses horizontal beams (fig 13-i) that pass through the hull (fig 13-ii)andareboltedinplace(fig 13-iiiandiv).Theboltspassthroughthebeamsand there can be fmm I to 6 bolts as each connection point however more can be added if desired as part of this claim. The longer hull curves in at the holes for the beams (fig 13-v and vi / fig 15-iii and iv) thus the bolts are going through part of the hull. This design also allows for the addition of an optional fixed shelf (fig 13-vii) below the beams on the longer hull, allowing for addition bolts to go through if an engine of significant power output is used. The surface of the beams at the bolting point are coated in rubber or foam (fig 13 -viii and ix / fig 15 -i and ii) providing shock mitigation for the beam.
3) A powerboat using the hull connection method as described in claim 2) that can have from one to n where n is an unlimited number of such connection points on the hulls.
4) A powerboat according to the preceding claims that can be quickly converted for different roles such as rescue, racing, fishing, leisure.
5) A powerboat according to the preceding claims that can have different hulls that are fitted out for different purposes quickly added or removed to the boat 6) A powerboat according to the preceding claims that can be disassembled. The connection beams and smaller hulls can be placed inside or on top of the larger hull to reduce storage area.7) A powerboat according to the preceding claims that can have any damaged hull or beam quickly replaced.
