10 Metre Trailerable Monohull

This is a custom designed 10 metre I have designed for DIYNO Kitset Boats. The boat is being transported home to the owners shed after the hull and deck have been fabricated.
The boat will run an IVECO 400Hp engine and a Konrad sternleg.
The owner wanted a boat that would cruise comfortably at 18 knots so the hull has been optimised for that but it will have a top speed of 32 knots.
I design alloy jig/trailers for the DIYNO KItset Boat range. The alloy jig becomes the boats trailer. And they are the best trailers available. Hull matched to the boats hull so easy to launch and retrieve and so quiet on the road. They fully support the hull with no point loading.

WASP 915 composite pleasure boat

Shown are the preliminary sketches for a 9.15 metre WASP powercat. Designed to fit into a 30 foot marina she is 9.14 metres long with the motors down. Accommodation features 3 double beds, separate shower and toilet. There is small lounge below decks and a dining/lounging are in the raised wheelhouse which also houses the galley. The cockpit is two steps down from the wheelhouse and features seating both sides. I have used a plumb bow design mainly to maximise the hull parameters within the 9.15m berth restriction.
Power will be 2x115-150 Hp outboards or there is an option for twin jet drives. The owner chose the WASP hull for her shallow draft with exceptional sea keeping qualities and the volume of accommodation provided by the WASP hull form

Rêvo Boxta 45

Rêvo Boxta 45.
4-5 seat Non Reinforced Plastic (NRP) jet boat.
The big strong silent type.
Commissioned by an owner of the smaller Boxta who said "the boat is so good I don't want to boat in anything else now". But he did want to be able to take family and friends aboard so commissioned the Boxta 45.
Here is what he said about it:-
The boat is so smooth and quiet and handles rough water so gently without banging.
Performance and handling are superb. So responsive.
She planes so quickly and at such a low speed. Coming down river is very safe. You have so much control.
She just goes where you point her. Handling is superb.
Can't believe how easy it was to get the boat back to water. And when we got it there it required so little water get planing. About one third of other boats this size.
It is one tough boat. We ran it 40 metres high and dry. No damage at all.
The boat is so easy to work on for maintenance. The full engine bay and cover is brilliant.
I couldn't be any happier. She is perfect.
Fully fabricated Polyethylene hull professionally designed/engineered and professionally built using new technology for an even better stronger boat more accurate hull shape.
Chevy L86 alloy V8
Scott 852 water jet.
This unit is fitted with a trim nozzle but the owner does not use it. He does not need to alter the trim at any speed. It is all set by the superior design which increases efficiency and improves handling making the boat faster and safer. No chine walking at speed in this boat!
125 Km/Hr top speed.

This 8.8 metre jet boat is a custom design for DIYNO Kitset Boats. The owner/builder was originally looking at a standard 801 but his choice of engine put it outside the skope of that hull so we have done this custom design for him. This is the largest boat to utilise my alloy jig/trailer option. The alloy jig becomes the trailer once the hull is constructed. Very good light, strong and quiet trailers which are easy to launch and reteieve the boats from. The full weight of the trailer is about half of a steel trailer weight, which in this case puts the all up weight of the boat with fuel and trailer under 3,500Kg.
The boat is 8.8 metre hull length, 2.75 metre beam. Engine is a Duramax putting out 450Hp coupled to a Hamilton Jet 274.
Speed will be 41 knots. I will post progress of the build as it goes.

This is a small water taxi being built in Fiji for the tourism sector there. It utlises my WASP powercat hull form which is ideal for this type of boat.
Key features of the design are:-
Able to operate at any speed
Very dry boats
Very safe in all sea conditions
Great load carriers without detriment to performance
Very stable but without the quick motion of other powercats
Leans inwards in a turn
Very efficient without the use of foils
Great access on and off from the bowramp steps.
Also good boarding platforms both sides at the stern

The first boat will run a single 60 Hp outboard engine centrally mounted. It will carry up to 18 people at 16-18 knots. Two subsequent boats will run twin 60 Hp outboards.

WASP 825 Whale Watch Boat

This boat is being cut now and will be in FIJI ready to start assembly prior to Christmas. This open model is for whale watching with 10 passengers but there is a semi-enclosed version also for guest transfers to and from resorts in Fiji. Benefits are very stable, very dry comfortable ride in open water and very efficient without the the expense and problems of a foiled hull.
The whale watching boat has side doors in the hull to get passengers in and out of the water to interact with the marine mammals.

Construction started on the Rêvo WASP 1302 45 passenger ferry

Covid 19 slowed progress but the kit set finally arrived at Cobra Boats Fiji. They haven't wasted any time getting the boat finished to hull and deck stage. The boat is on hold until the boarders are open at which time final fit-out will happen. Another quality build from Cobra Marine.
LOA 13 metres
2x 325 horsepower Suzuki outboards
45 passengers and crew combined
Two heads, male and female
Speed 25 knots laden.

Remedy 31 powercat nears completion in Fiji

My new 31 foot semi planing powercat is nearly ready to launch. Designed for charter work in Fiji, she carries 18 passengers and 2 crew. Powered by twin 150 horsepower outboards for a top speed of 23 knots laoded. The boat has two heads, forward in each of the hulls and has a bow stair and stern ladder for easily taking onboard and disembarking passenger. She draws less than conventional displacement powercats and has the ability to fully plane when in light ship mode giving a top speed of 29 knots. But most of the time the boat will operate in semi displacement mode at around 15-18 knots.
