you do not need a point on the back (stern end). please review the above site for answer’s to your questions.

some tips:

A flat bottom is recommended. A V-shaped bottom is likely to tip over unless the V is very gentle.

The lowest center of gravity is the most stable; kneeling or standing will cause you to tip over.

Longer boats go faster, but they are harder to turn.

Boats shorter than 10 feet are difficult to steer.

For height, allow about 18 inches for you to sit and paddle effectively without the edge of your boat blocking your arms.

For width, figure about 18 inches for a kayak, about 23-24 inches for a canoe. Figure about 30 inches maximum for 1 person, 48 inches for two people.

hope this helps

I have built my own boats for over the past 40 years. The first 10 were all small; canoe, kayak, dinghies, etc. and then I moved up to a small houseboat, then a small tug boat, a sloop, and the last 2 have been 44" catamarans, one sail and one power.

I obviously have a mental problem, I am a silly stubborn old man that still has a youthful passion and fascination for all things boats & boating. I would encourage anyone to build their own. . . but I also know, it certainly is not for everybody.

While you can save a bundle of money by building your own, it is NOT a cheap endeavor. Fact is, you can buy a good used vessel these days much cheaper then you can build.

So, if you are thinking of building you own as a means of getting a boat you otherwise could not afford – think again. You can buy good seaworthy used boats much cheaper then you can build you can build the equivalent boat.

On the other-hand, if money isn’t "the only" factor to consider, then building certainly offers some great benefits.

I built my last two boats for two primary reasons:
1. I knew I would never find one to fit my wants & needs in a production boat. They just don’t make what I want.
2. Money! I don’t have tons of it. Yes, after I just told you that you can buy a used one cheaper – I built my own because I have much-much more time then money. My savings over buying new is my own labor (and whatever labor I can beg, borrow, or trade for with my two adult sons).

So compared to buying a new one, I know I am saving at least 60% off the price of a new one, but still, I could buy a suitable production vessel on the used market for a whole lot less. I just wouldn’t get what I want.

However, if you want to check it out, I have a couple of links for you. One is all about sailing and living aboard. The other will take you to the boat-building, boat plans, website of Glen-L. I have been doing business with these people for 40 years. They are good people, and I highly recommend them and their boat-building plans.

Often if you can cope without having the newest flash boat you can get a competitive older boat that even with a new set of sails will cost much less than new.

You can build very simple PDR (Puddle Duck Racers) with surprising performance for as little as a few hundred dollars rigged, you could build classic designs like the Heron in stitch and glue which might set you back 3 or 4 thousand (or more if you use top shelf everything) Perhaps a lightweight Sharpie for $25,000? You might want to look at some of the Welsford designs, or even just get on a keel boat as crew for a few races to see what it is you really want to get into.

Really the variety and budget is huge – and in todays market very good deals can be got for quite new boats.

Good luck.

It’s a powerful software for designing boats & ships that are a part of modern naval design. It does a pretty good job of building complex marine parts as well. There’s a full library for it.
