Running through HullSpeed (a part of our Maxsurf ship modeling program suite), the result is a light hull built in our standard material epoxy-glass-plywood composite construction. The deadrise is 58 degrees at the cutwater, about 16 midship and 10 degrees at the transom, the Mushulu 14 has enough vee to handle choppy seas without problems and her moderate beam produces great stability and lift for planing at low speeds.

As the chine rise is very progressive, the Mushulu 14 does not have an obvious hump in its transition from displacement speeds to planing, resulting in a good moderate speed boat. Overall, the Mushulu 14 is able to maintain moderate speeds between planing and displacement without pushing a huge bow wave.
The following drawings will be supplied. Back up service is also provided as needed.
All plans provided are drawn on 2ft by 3ft sheets
Amateur Home Builder
We have boat plans (both yacht designs, catamaran designs and power designs) for all sizes. From the 12ft Mushulu Dinghy stitch & glue yacht tender to the Oceansky 57 catamaran. We design timber boats, plywood boats, strip plank boats, fibreglass composite boats, steel and aluminum boats to very modern styling for both monohull designs or multihull designs, powerboat or sailboat and in round bilge, multi-chine or radius chine hull forms.
Design Brief:
Based on the successful Mushulu 14 series, the Sandy Strait 14 is the same design but with a different interior. Keeping with the same concept, the Sandy Strait 14 has to a simple open plan design, with the priority being for easy planing at low speeds, great stability whilst at rest, and reduction in fuel consumption without compromising the strength, durability and safety of the design. Careful consideration was given to loads of storage lockers, side shelfs for all that fishing gear that needs to be kept handy and comfortable seating throughout, whilst still providing a stable platform for fishing or other recreational activities without compromising safety for those on board.
The principles on which our boats are designed are for strength, safety, seaworthiness and comfort. We will not sacrifice these in order to gain high performance. Nevertheless, our boats have a reputation as excellent performers. They are also known for their strength.
Designed also for ease of construction for the first time builder, the Sandy Strait 14 is light enough to be easily trailerable for adventures in distant places. But overall, it had to be simple and easy to build, without spending everything you have.
Australian Builders Plate
The purpose of the Australian Builders Plate
The Australian Builders Plate is a national initiative that will make boating safer by providing vital information about the capacity and capability of boats. The Australian Builders Plate requires boat builders to determine boat-specific information and display it on the plate in a standard format. The information that needs to be provided includes:
- recommended maximum engine power rating and engine weight for outboard engines
-
recommended maximum person capacity and maximum load
Flotation used (basic or level)
CHOOSING YOUR HP REQUIREMENTS
To determine speed and Hp requirements, simply look up on the graph what Hp you would prefer and scroll down to the speed given. This is for MAX Hp vs Speed.
For "cruising" speed, simply "multiply" the max Hp chosen by .8 and then note the speed for that given new HP.
Example:
Chosen Max Hp = 25,
Speed = 28 kts (32 mph/ 52 kph)
25 Hp (max) x .8 (80% throttle) = 20 Hp
refer graph: Cruising Speed = 26 kts (30 mph/ 48 kph)
