| The main features of the TUNA line of sport utility boats.
Tuna 25 Walkaround is the first configuration available. The boat will also be available as a Centre Console, Full Cabin and an Inboard Outdrive engine version. Please inquire. Hull characteristics. 1. Relatively high deadrise at transom(19.5 degrees), makes her much more comfortable in sea way than the majority of boats this size, whose deadrise is generally in the 13 to 18 degrees range. 2. Chine flats are 9� wide aft, gradually narrowing to 2� from amidships forward. The wide chine flats aft give the hull extra lateral stability, while narrow chine flats forward prevent slamming against oncoming chop. 4. The hull itself is 25 feet long, 27 feet including the engine bracket/swim platform. Including the outboard engine, the boat is just over 29 feet long. |
| Construction.
1. The maximum beam is 8�-6". This is the legal width limit for a trailable boat in B.C., without special permits. 2. Whenever possible, welds are avoided: entire cockpit sole(from the bow to the engine bracket) is made of only two pieces, welded together, welded to topsides(side plates) around the perimeter, and slot welded to structural members underneath. Each hull half is one piece, so are side plates. This aproach yields a much fairer hull. 3. The hull is framed longitudinally, which, again, produces a fairer hull, eliminating the "hungry horse" look of many metal boats. 4. The structure consists of longitudinal girders and transverse frames, which �egg crate� into one another to make assembly quick and accurate. 5. I believe in being able to access and remove the fuel tank, if necessary, even after the boat is completed. This is acomplished by locating the fuel tank under a �soft patch� in the cockpit sole. 6. Materials: Bottom - 1/4" - 5086 H116 Sides - 3/16" - 5086 H116 Cabin - 1/8" - 5052 H32 Function. 1. Transom height is 25�. Using the engine bracket, instead of mounting the engine(s) on the transom, allows the engine(s) to sit a bit higher and further aft of the end of the hull. This improves the "hole shot" and allows the propeller to work in less turbulent water flow. The use of a 30" leg is not necessary. 2. Recommended power for this hull is from 150 hp to 500 hp, single or twin installation. Tuna Walkaround with a single 300 hp Mercury Verado achieves a speed of 50 m/hr, plus. 3. Custom alterations will be considered (additional and/or different configuration of lockers or seating). 4. Cockpit is self-bailing. 5. Built into the cockpit sole, on centre, is a 50 USG fish hold, with a flush lid, built-in drain and a removable liner. 6. It is possible to make the boat unsinkable(not required legally at this size), by filling the unused cavities under cockpit sole with foam. CLICK HERE TO SEE A FREE PDF STUDY DRAWING |
