Re: Inboard Diesel Jackshafted Vs. Twins on a Seamark
Check out the pics I posted of the "Hawaiian" SeaCraft. As mentioned the hull is stretched to 26' and has a volvo AD41B 200 hP diesel in it. The boat is fast with the direct drive (low 30 knot range) and burns about 2 gph at trolling speed. They are much faster with the VP Douprop (mid to high 30 knot range). That may be attributed to the back end being flattened out vs. the original deep v of your classic. Most seasoned fishermen in Hawaii run diesel power (unless the boat is too small or they can't afford it) in their Classic SeaCrafts or 24' and 26' Yellowfins (modified SeaCraft hull). The first boats like my dad's were a bit heavier than the newer ones as they used a good amount of wood in the construction. My dad's boat was filled with seven Ahi from 110 lbs. up to 170 lbs. (Hawaiian name for Allison Tuna), over 700 lbs. of ice alone + brine, a crew of 3 weighing 140 lbs., 165 lbs. and 220 lbs. Plus all the rest of our gear (we fish 5 Penn 130's). They came back in 15-20 ft. seas on the windward side of Oahu and the engine still had more throttle. Weather conditions didn't allow my dad to use more power and the motor was over 10 yrs. old. Hope this helps you decide and if you have anything you'd like to ask in specific give me a holler. Aloha, Greg
