my wifes uncle lost his 25' sailboat and asked me if I could tow it back home for him. I've got a 21' trophy with a 1984 yamaha 115 on the back. the tow is going to be about 10 miles across the puget sound. we are waiting for a decent day to do this. any suggestions? I've never towed a boat this large or this far. should I even do this?<br /><br />lingcod

Re: towing a boat

I don't think you have any problems, use a long line and go slow. Why don't he sail in. ;)

Re: towing a boat

Make sure you have plenty of fuel. You are towing a displacement hull so you will need to go slow as suggested. You will quickly find the point where both your boat and the towed vessel are comfortable with each other. The other option is to borrow someones kicker (assuming the sail boat has a bracket of course).

Re: towing a boat

I have a 27 ft sailboat that I have towed a few times, although not in puget sound, but like chief and upinsmoke said, keep your speed down to around 5 mph and you should be good, a sail boat is very easy to get moving in the water as long as you don't try to exceed hull speed (unless it is a catamaran)... also tie the tow line to the bow of the sailboat and to the mid-ships of your power boat, not the transom...if you tie to the transom it may become difficult to steer.... you should have no problem...... :) :)

Re: towing a boat

as a sailor i would find a someone to help sail it back and use this to teach the owner a littel more about sailing<br /><br />even if he had to pay someone it would be a great learning tool<br /><br /><br />tommays

Re: towing a boat

Make sure that your tow line is long and instantly releasable and someone is close to it to release it if required.

Re: towing a boat

Also, while towing, keep the two vessels "in step". This means your tow line should be just the right length so both vessels are on the crest of a swell or the trough at the same time. This will prevent shock loading the tow line and it will reduce stess on deck cleats. Being your towing a sail boat that most likely doesn't have a bow eye, you will need to rig a bridle. The bridle should be a length of rope about 15 to 20 feet with an eye at each end that you will attach to a cleat on either side of the bow of the sail boat. Attatch your tow line to the middle of that bridle. This will prevent the sail boat from yawing too much and it will reduce shock on deck cleats. <br /><br />Getting the sail boat to the dock at your destination can be tricky and I suggest you have a helper. You will want to put fenders on one side of your boat and bring the sail boat along side. Make sure that the stern of the sail boat is a good 5 to 10 feet forward of your stern when you tie the two up. Make sure you run two spring line as well. One from your stern to his bow and the other from your bow to his stern. Snug these line up and you're good to go. When towing alongside it's important to reduce throttle to idle, turn your wheel, and then increase throttle whenever you want to turn. The boat will not respond otherwise. Let us know how it goes and ask any questions if you need to. Good luck. :)

Re: towing a boat

gonna do this on sunday weather provided. we are hooking up to a mooring bouy so trying to dock is not a problem. i tried to lend him my kicker motor but he would rather tow the boat. he said that he has not been out on the boat in 2 years except to row out and have a little party. the boat has not been untied from its bouy in 2 years. what a shame. thanks for all the help, i'll let you know how it went.<br /><br />lingcod

Re: towing a boat

I have towed boats twice my weight many times and that boat will weight twice what your boat does.<br /><br />Yes you must go slow about 5 MPH but here we are talking Water Speed not GPS speed. So if you have a 3mph tide it may help you or almost stop you.<br /><br />Stern Eye bolts normaly pretty strong but check them and make sure they thru bolts not screws and they have big backing washers or a backing plate so they do not pull out. Do not use you stern deck Cleats.<br /><br />If you do not have a towing bridle then you need to make one so you can turn. If you just tie to one side or the other you will not be able to steer your boat. If your stern deck cleats are good and strong then you can use them. Take a short peice of line and at least 3/8 inch (1/2 inch better) and tie to one deck cleat go down to stern eye on that same side and go thru it twice. Now go to other stern eye and go thru it twice, leave enough slack to let line run about 4 feet behind stern then tie off to other stern cleat. If you have any floats you can add them to this line just to make sure has no chance of getting in your prop should you stop or back up. Going thru your stern eyes twice will take most of the strain off you deck cleats. One other reason for useing stern eyes is if tow line should break then better chance the line will hit the back of the boat instead of the people on board. Now Your tow line is tied in a loop around the center of you towing bridle, This way it can slide from side to side to allow you to turn better. If you have any swell adjust the length of tow line so sailboat is on the same part of the next swell as your boat is. When you get to your destination go dead slow and keep line up out of motor. Shorten your tow line. Also need to check the bow eye on the sailboat and make sure it has big backing washers or a backing plate. Bow Eyes normaly very strong.<br /><br />Towing can be very dangerous. Nylon line works fine but if you should pull to hard the nylon line can be deadly. It will streach and if it breaks if will fly at your boat and can break limbs or knock someone over board. On my boat all would wear Life Jackets but then in large water we alway wear them. <br /><br />On the Sailboat I think you should have at least one on board with a radio. They should have a good anchor just in case.<br /><br />Use the largest tow line you have if it is in good shape.<br /><br />If you have a lower pitch prop use it for this tow. Make sure you have twice the fuel you expect to use. Since you have a kicker I would also start it and add some power. Since your motor will be way over proped to pull this weight take it easy and use both motors.

Re: towing a boat

My 02.<br /><br />Have someone steer the sailboat while towing. Have a big anchor in the saiboat's cockpit for emergency stopping. Tow with a nylon with diameter that will stretch and absorb shock loading...1/2" dia is about max size for that tow, I wouldn't go larger. Have a sharp knife ready on each boat to cut the towline quickly. Tow at "sailboat" speeds for best economy and least strain. <br /><br />For safety be aware what can happen...I saw a guy get a broken leg once from standing on the deck next to the tow line. His 35' sailboat was being pulled off a sandbar. The towboat was a big diesel and used heavy throttle to get the sailboat off the bar. The line parted at the tow boat side and whipped back and hit his leg. He spent 10 months with his leg in a cast. He should have been back in the cockpit taking cover.

Re: towing a boat

Make sure the tides and winds are favorable. You don't want to be towing this boat with a South wind and a strong incoming tide the 10 miles will feel like 20.<br />Matt

Re: towing a boat

just got home from towing the uncles sailboat. wow was that a long trip. 2 hours to go 10 miles. slow and steady all the way. no issues though. bridle worked great but should have had a shackle to allow for smoother sliding of tow rope. I can honestly say that unless i'm trolling for salmon, i will never go that slow for that long. hard to stay awake that long. thanks for all the help. as you stated take it easy and it will be easy. i did and it was. thanks again<br /><br />lingcod

Re: towing a boat

Great job, Got her home safe.<br />Yes on the bridle some will use a special roller to allow the rope to move side to side smother. I found if lighten up on the power offten will slide over easy. also the length of the bridle makes a difference.<br /><br />Home safe, Great Job.
