towing

Hello everyone! We just bought a 2101 seaswirl striper (21' walk around) to tow behing our 38' marine trader.* The*striper has an outdrive* (I/O)* so I will not be able to get the prop out of the water when towing.*My question is when towing should I leave the striper in or out of gear as we speed to our 8 knot cruise? Thank you for the site and for everbody who will reply!* Brett

towing

With a small outboard I've towed them with the motor down and in neutral.* Otherwise the motor has a tendency to crank up.* I'm assuming you're talking about an I/O so that might not happen so easily.* Freewheeling an outboard won't hurt anything, don't know about an I/O.

RE: towing

I have the 140 HP OB in neutral and up.* However, the Run About has a deep V hull and tracks straight behind the Eagle. I use the anchor bridle as a tow rope which also help to keep the run about centered. If the boat is flat bottom you might have to have the engine down so it tracks straight.* As for neutral or in gear I would call the dealer.*

RE: towing

Woody, when you say the outboard has a tendency to "crank up" do you mean it can, or will*start?***From the water flow turning the prop? Even at slow trawler speeds?

I have heard people talk about that but never thought it could actually happen, have you seen it?

thanks Steve W.

RE: towing

wI towed a i/o for years tilted up in neutral behind a planing boat. No problem. It was a merc.

RE: towing

I have an outboard deep vee (classic 1975 20' Seacraft CC) that tows well with the outboard in neutral and tilted up so just the skeg and a little prop is in the water.* I also have a 20' shamrock inboard that tows great (it is a keel drive) but I 'block' the drive shaft with a shaft lock I made up as the freewheeling heats*up the transmission too much for me to be comfortable. I would think with an I/O you could trim the drive up enough that it would not freewheel (or not much).

Towing puts a huge load on both boats, I recommend you get a good tow eye (check out toweye.com) made up that mounts just above the water line on the Sea Swirl and*to use a bridle on the trawler.

You now have imho about the best 'dinghy' ever!* When we are in the Bahamas, we spend almost every day on the runabout and cover much more area that we would with just the big boat. When at home in the marina,many times we just take the runabout out for a few hours and it's a blast.

*Yes, if you had a small one, like 5HP, and it was a two stroke, and not set up as a kicker, *and you left it at WOT, and then dragged it at maybe 9 Knots, it might start and then it starts running all over the place.

The OP had a much bigger engine so this is probably not applicable.* Just thought I'd mention it.* I tow a dinghy sometimes and I make sure it is in neutral, but I also pull it out of the water.* I find that the length of the painter is more important than whether or not the lower unit is in the water.

I have towed an inflatable soft bottom without the motor.

*You have to keep an eye on it in the wind. I have seen my fly like a kite in 30 knt winds.

Actually leave the water.

RE: towing

Before I put the electric winch on my crane I used to tow my dingy around a lot.
12' tinny with 15 hp.
It didn't make any difference if I had the motor tilted or not she still towed nice and straight.
Have allways used a bridle tow arrangement .

RE: towing

Last summer I towed my 20' comp ski boat all over on the Columbia and Snake rivers.. on a river I never even knew the ski boat was back there... except it cost me a 1/2 knot of speed. I have towed our 12.5' hard bottom 40hp dinghy in some pretty boisterous conditions.. the tow line length becomes pretty important to get it to track straight.

I watched a 100' yacht with a 25' fishing boat in tow doing at least 20kts on what must of been 400' of tow line.. the loads must of been huge on both ends!. They were headed up the middle of the Straits of Georgia. I guess no matter how big the yacht someone will always want a dinghy that is too big to load on top!

RE: towing

bringing back this towing thread...

how much line should be used for towing a 13 RIB?

Not having done this before, what are the big NO NO's?
guess backing up into the tow rope would be one problem...

RE: towing

If you are using a tow rope and not the painter Be sure it is a floating line.

Tow her back far enough so she rides just behind the hump and stays on an even track not to much wallowing back and forth.

RE: towing

If you want max efficiency, I would put it on the front side of the hump so it surfs....but like SD said, it has a tendency to wallow around back there like that. So your choice, stability or efficiency...there is always a trade off.

RE: towing

just a follow up to this thread..
we towed our 11' RIB recently

on the way out we used a 350# floating line as a bridle with the outport in the down position.
the line broke at seas, i was able to re-trieve the RIB and re-tie it using two docklines tied together.

on the way home, i raised the outboard and it went much better.
i would not recommend towing with the outboard down, it adds significant drag.

we were going around 9 - 10 knots on the way out and 12-13knots on the way home
btw, when maneuvering we would pull it up real close to no chance of rope meeting the props.

What if you need to come to a stop for some reason. The tow rope could easly sink under the boat if you can't get back there to handle the line.

For instance I am cruising along and find myself surrounded by a commercial fishing line strung across my path. I need to stop and figure out how to get around the lines. If someone else is at the helm fine. I can handle the tow line. If it is my brotherin law. I have a tow rope in my prop for sure.*

With a floating painter. No worries

*I managed to do it.* Just got sucked under somehow.* I always shorten the painter or move the dinghy to midships before maneuvering.* I've seen some people put the painter through a "fun noodle" which looks quite effective though.

RE: towing

Yeah, but the chances are it won't happen as often.

*Or perhaps if you do have a sinking line you will be more carefull about where the line is at all times.

I have trouble keeping track of my car keys.

You are probably right.* I will be more aware. I just have never had it happen to me.

Famous last words.

RE: towing

Several years ago I saw a sailboat suck his floating line into the prop and it was down a ways. It was a bit of a combination of suction but also backing over the line and forcing it under the water. Several of us yelled but of course too little, too late.

towing

This sailor doesn't look the least bit worried about the line to his dinghy.



This is the southside of Carquinez Strait, betwixt Crockett and Port Costa; sailor is heading eastward to the delta, and the cruiser is anchored in a flood tide.* During the 19th and into the early 20th century, there were many commercial docks here, as evidenced by the many long-remaining piles.
