right here that the only advantage of a 10 h.p. motor over a 5 h.p. motor 

 is that you can go faster from one place to another and thus extend your 

 field of operations, but you cannot get any more in your dredge, or if you 

 do, it is apt to stay on the bottom. 



Even though there is never enough room on a small dredge boat, I 

 would recommend that your boat be equipped to sail. I would also advise 

 that you learn to sail it before your motor fails during a heavy sea, and 

 you have to. The narrow stern is about the only drawback to a dory as a 

 dredging boat. However, its redeeming features of seaworthiness and 

 adaptability more than make up for the cramped quarters. 



One very great advantage of a dory using an outboard motor over a 

 boat using an inboard motor, is that you can always take the motor out, 

 land through the surf, put the boat on a trailer, take it somewhere else, 

 launch it through the surf, and dredge there. 



There is no doubt about it, power boats with inboard motors are by far 

 the nicer to dredge with, especially if they have a power winch to pull up 

 the dredge. However, here even more than with rowboats, be sure to get 

 a seaworthy craft, as you are likely to wander miles from shore and 

 possible aid. 



If the boat is large enough it is advisable to rig some type of derrick or 

 frame on the stern to facilitate getting the dredge aboard. 



Dredge Line. The simplest type of dredge line is rope. Some prefer to 

 use 1/2 or % inch manila rope as it is large and easy on the hands. This is 

 very good if one is dredging on a shallow, rocky, or shale bottom and does 

 not get it permanently fastened to the bottom. This heavy rope, however, is 

 too bulky for anything but very shallow dredging (5 to 20 fathoms) and 

 is also much more expensive than the smaller rope which is just as good 

 and sufficiently strong. My father and I have dredged in as deep as 50 

 fathoms with 14 '"^^h rope by fastening small weights to the rope at 

 several places. These weights are necessary in deep dredging with rope 

 as it has a tendency to float and pull the dredge off the bottom. 



To dredge in more than 20 fathoms with rope, it is necessary to devise 

 some sort of windlass on which to wind the rope. If you do not use a 

 windlass, it always seemed to me that the rope becomes more tangled when 

 an attempt is made to coil it when dragging in the dredge than if simply 

 allowed to fall naturally. If you buy a full coil of rope as it comes from the 

 manufacturer, be sure to ask the dealer the correct way to open it and 

 take out the rope, as it will be full of kinks, one for each coil of rope, if 

 not done correctly. Incidentally, if this should happen, pull in the rope, 

 stick the end up through the hole in the center of the coil and pay it out 

 from there. This will remove all of the kinks and the rest of the rope 

 will not be kinked. 



If you are going to dredge very deep (50 fathoms or more), it is much 

 more convenient to use cable, as rope has a tendency to float and pull the 

 front end of the dredge up. The chief objection to cable is the cost. A 

 thousand feet of good cable probably would cost about $100. We have
