Location: Marshfield massachusetts usa designing a fast rowboat I live in New England (USA) and we have a growing sport of open water ocean rowing racing. Location: Lake Michigan I don't claim to be an expert, but for speed, little to no rocker is good.
A race boat would have to be longer (the longer the better) and a bit wider (but not much wider).
Location: Cornwall, England Take a look at a gig, they don't come any faster or sweeter (but I'm biased, we've raced 'em in Cornwall for the past couple of hundred years! Location: Eustis, FL Build her light and put some foils on her, so you can spank the fleet. Location: Marshfield massachusetts usa Safewalrus, We have the gigs here too.
Location: Marshfield massachusetts usa Terhohalme, Very interesting piece of work, I'd be interested to find out more about your boat. Location: Trondheim, NORWAY I think you could try minimum wetted surface, long waterline and optimize the Cp for your speed.
Location: Marshfield massachusetts usa Safewalrus, That Flashboat, VERY interesting can you point me to plans? Length must be an important part of the speed equation,a long narrow boat will always be faster than a short wide one.
1 ) A fast rowboat will probably be as long as possible and because of its length will be able to have as narrower beam as permitted by the required displacement.
Bow steering ,yes like you guys I am concerned about bows digging in and directing the issue.


There must be a point where the trade off between wave making and wetted surface is at an optimum..

It was popular in the Rangeley Lakes of western Maine where it was used to row for lake trout. Looks like a very fine entry and straight run with a lot of flare in the mid sections to get enough spread for oars on gunnels ( a requirement in our class). A skeg continues forward with an 1-inch keel, with a brass keel strip for added protection. My ideas come from eight years of racing and constant observation of our own two boat as well as the boats we race against.
Weather prediction for our 4 mile race on Saturday is for temps to be 53 degrees F and winds to be 10-15 kts. Rules are almost non existant and are limited to number of oarsmen,fixed or sliding seat, or general clasification ie: work boat or livery boat.
I had hoped that this thread would bring out the real designers and a discussion of general design theory.
To win, a boat must be able to stand up to some tough conditions yet have enough speed to achieve 6 knots+ in calm conditions.


I'm learning a computer program for boat design and have a couple of promising sketches worked up. Might put a look of dismay on the Cornish boys faces - to be beaten by a yankee 'flashboat' 'specially if they don't know you have one!
Tad Roberts,a designer in Washington State, a forum contributor, was kind enough to send me a set of limes showing his concept of a fast row boat, and they gave me a lot to think about. I would appreciate a general discussion of design factors from people who are more knowledgeable than myself. A large part of his ideas will show up in my next boat if I can just get the station molds to print out on my program. The boat is surprising light, about 100 pounds, and could be car topped, but I prefer a small hand trailer or a small boat trailer. The hull is made of cedar strips; the rails and decks are mahogany, and the seats are cherry.
Whatever she does, it's a fast boat (good crew too ) Does semi-planing happen, is it good or bad? Current plans are to put some rocker in forward to reduce bow steer and reduce wetted surface.
