Hello, I just took my Dauntless 13 out for the first time this weekend. Itís a great boat, but to get on plane someone has to be sitting in the very front to balance the weight. We would like to be able to sit on the rear bench seat and not have to sit in the front getting wet. We take about 450 pounds of gear and people. Would a doel fin allow us to get on plane with all this stuff in the back where itís a better ride and drier? The engine is a 50 horse Yamaha 2 stroke.

Note, I might put in a 27 gallon gas tank, so I will have a lot of weight in the stern.

Other then that it did fine in the Delaware Bay on Saturday. We took it out to the shipping lane, but coming back we had to fight thru some serious waves at 4 mph. Foolish, yes, but we have been trying to get the new boat out before our guarantee expires.

So, will a doel fin help? I read back and some people say they do, and others take them off.

I put a Doel-Fin on my Sport 15 and it made an unbelievable difference. I just put one on my Montauk and it helped, but not as dramatically as it did on the '15. I would say go for it, it will probably help. Also, if your bow is normally too high, try lowering the trim pin (proper term?) on the engine.

I would, but the way the swim platform was put on I can not get it out to reset it without taking the engine off. Its a shame, but o well.

I ran a Dauntless 13 with a fin for five years. In my opinion it does need the fin, running without it greatly reduced the ability of the boat to get on plane. The hull does not have a lot of lift area in the stern. I think it was designed around the old 177 pound Mercury 40 HP 4 cylinder engine.

You didn't specify what engine you were running and if it had power trim. Come back with some more information.
Doel Fins, etc, react differently on different hull and power combinations. It's a cheap try for an improvement. If it works, great if not there is little lost.

I put on a Davis Doel Fin from west marine. I couldn't find my right angle drill, so I got a little creative with a grinder. This weekend i will take it out.

I put on on my 13' sport with a 25hp Honda and I love it. I put on the SE Sport 200 from Cabelas $39.95. Before I had to get up to 16+MPH to get on plane, now I'm on plane at a little over 12 MPH. I don't know if it hurt my top end.
