                                                                                              THE  TROPIC 12

      Think of a place you want to go on the water and the "Tropic 12" can get you there. Whether you're fishing, diving or just having fun, the Tropic 12 is an ideal family/ multi species fishing boat. Easy on the pocket and packed with features left only to your imagination, the Tropic 12 maximizes it's space with a wide beam, stable hull and an open and roomy interior for loads of storage and fishable cockpit space, whilst out on the water.

      The heart and soul of the Tropic 12 lies in its modified-V hull, designed for the tough demands of fishing or family excursions, whether your running the estuary's of the Gulf or fishing the freshwater river backwaters and lakes. But the real beauty of the Tropic 12 is its wide beam and shallow draft, enabling you to navigate across shallow flats, up coastal rivers and even into tidal creeks. Overall, it's the perfect all rounder that's easy to handle, easy to trailer and more importantly...easy to build.

The Tropic 12 is in a class of its own. Her lines easily distinguishes it from any other boat, even at a glance. While enhancing style and function, the Tropic 12's wide-open cockpit, soft dry ride, ample storage, "V" hull (not flat bottom) and a list of features limited only by your imagination, allows the Tropic 12 to perform like no other boat in its class.
As an all round fishing boat, it makes it an unbeatable choice for the fisherman who wants a serious boat that is easy to trailer, yet delivers the absolute best in safety, reliability, and angling adventure.

   The Tropic 12 Specifications 
I'm happy as the proverbial pig.
Went for another trip in the boyne river today but in a different area. This spot is just upstream from the bruce highway bridge at Benaraby. Not exactly a ramp, more like a depression in the river bank as the pic shows. The Tropic 12 doesn't need much water to launch. 24kts according to Lowrance
 It was a lot of fun though :lol:

 Boat Designs with "Reel Flare"

         We have boat plans (both yacht designs, catamaran designs and power designs) for all sizes for the amateur boat builder and Professional boatbuilder. From the 12ft Mushulu plywood stitch & glue power boat design to the Oceansky 57 strip plank composite multihull design. We design and build, plywood boats, strip plank boats and fibreglass composite boats to very modern styling for both yacht designs, multihull designs and power boat in round bilge, multi-chine or radius chine hull forms, including aluminum drift boats, aluminum landing craft, aluminum monohull boats, aluminum catamarans, aluminum special purpose boats, and aluminum RIBs

The construction is epoxy-fiberglass-plywood composite, a stitch and glue composite system designed for efficient and fast building. To put it another way, the hull material is engineered as a fiberglass laminate whereby the plywood is treated as a thick, yet weaker laminate within the fibreglass schedule.
Building the boat is easy. The builder simply assembles the hull as a plywood boat first, then glasses the outside and inside with fiberglass, to produce a strong composite hull without all the time consuming woodwork associated with traditional plywood on frame. Bog, fair, paint then time for the internals. Its that easy
