    Default Atkin "Elon Jessup" Outboard Skiff

    I’ve been looking for a design for a traditionally built skiff. My father-in-law has a place on the water in Maine and I want to build a boat I can leave there, so we don’t have to trail a boat with us when we go up to visit.
    The design that drew my attention was the Atkin “Elon Jessup” outboard skiff. I bought a set of plans and I have been lofting them up in my barn. I thought lofting was all complete and I have started on building the station molds and gluing up the transom. A couple of nights ago, though, I came back to this forum to see if anyone else had built this design and posted it on the forum . To my delight someone else had. Here is the link. http://forum.woodenboat.com/showthre...My-Elon-Jessup
    “Doctor B”, did a fine job of building this boat and the thread that documented it, is a pleasure to read. She surely is a beautiful boat. At the end of the thread, of course, there are a couple of posts about the launch. However, it becomes clear that when an engine is mounted, the bow is too far out of the water and in order to sit close to the designed waterline, Doctor B has to load her up with sand bags at the bow.
    Reexamining the drawings, I can see that there is probably too much rocker at the back of the boat. The transom is fairly narrow and the weight of a 10 to 12 HP engine hanging off it, pulls her way down.
    I have two options, I could abandon this project and find another design that doesn’t have this problem or I could make some changes to this design to fix the problem.
    I know that many of you will get the RAGE!!!! because futzing with someone else's design is sacrilegious. I get it, but clearly the design could do with some improvement.
    I figure, station molds 8 through 12 could be dropped to the line that I have indicated in the plan and it would fix the problem. The molds would not have to be altered in any other way What does everyone else think?

    You are on the right track. I would try to preserve the sheer line/deck line so that the boat looks original. Drawing the bottom dead flat from transom to heel of stem will perform better than the way you have it drawn. The belly will make the boat ride bow-high, and pull a wave train aft at lower speeds. If it were my project I would redesign the bottom, and probably pull some of the pinched stern out.

    Look at these two examples of good flat-bottom pointy-bow 16' designs with tiller outboards:

    Thanks for your comments "Skiff Man" I was actually thinking of flattening the bottom at the bow end too, and, as you suggest, widening the transom a tad. Looking at the two examples you linked to, I can see even they have a slight rocker to the bottom.

    I too would flatten it out aft, or use very low power. (4hp maybe) For 10-15 hp, a bit less rocker seems like a benefit.

    OK, well, I think I need to start a new post in the "Design and Plans" part of this forum, as I clearly need to go back to the drawing board.

    Tapsnap have a closest look at one of the nicest boat designs in your size range.
    The Jericho Bay Outboard Skiff.
    Meets all your size needs.
    Has traditional roots - 1950s style. Simple strip plank construction.
    Can handle from 10hp to 25hp.
    Squatting at planing speeds has been designed out of it with a hook in the hull.

    Don, that is a beautiful boat. Certainly a possibility. Here is a link to a thread I started in the "Design and Plans" section of this forum. http://forum.woodenboat.com/showthre...drawing-board) Take a look and let me know what you think.
