Do Hydrofoils Work???
Thanks for the advice.
Randy "kshoaps" wrote in message ... Seems to me that adding 215# of sand in a small boat will degrade performance also. Interesting to know if a fin or the extra weight causes more decrease in performance--my guess is that you'd be better off with the fin. "Larry" wrote in message ...

I have a Glastron SX 195 with a 5 liter 220hp motor and I would like to be able to be on plane at a slower speed. I usually have to be going about 15 or 20mph to get on plane. Any Ideas??? Randy Before you go whole hog with the dragfin, have you tried a little weight and balance adjustments? Go to a hardware store and buy some empty sandbags. They're real cheap. Fill them at the beach and put them in a plastic kitchen trash plastic bag to keep the leakage to zero. Pack a few into the bow, way up into the point, and hold them there with some kind of strut like a 2x4 or boat paddle. 100# of sand way up in front, even just sitting on deck, is like adding a 250# passenger to the bow when the boat is plowing just before planing....without 150# more weight. The mass also helps keep the bow from bouncing up and down with the pressure from thrust and wave action....makes it ride smoother. I have a little Sea Rayder F16XR2 16' jetboat with the 175hp Merc Sport Jet power. There's 125# of sandbags in front of a wooden dam up in the bow forward of the bow seat locker to make the boat plane faster and act "bigger". Keeps the pounding down, too, in waves. On the port side, up inside between the cockpit bulkhead and hull higher than the waterline is a row of sandbags weighing about 90# as far up as I can stuff them, again held in place by a wooden dam to keep them from shifting. This counterbalances some of my weight driving from the starboard driver's seat while alone. When a second passenger is added (think bikini clad female on the way to the beach), she sits in the CENTER seat next to me, not way "over there" on the left because when she came aboard the boat was already "balanced" for the driver. She's just keeping it balanced on centerline.....(c; No underwater or stern fins are necessary draggin on the speed and performance. Larry W4CSC "No, NO, Mr Spock!
