Introduction
--------------------------------------------------------------------------------
For a long time the drift boat has been the famous wooden McKenzie style built in the 1930s and 1940s by Woodie Hindman or Tom Kaarhus from Norway in McKenzie river country. With the appearance of new materials such as Aluminum and fiberglass we have seen an evolution in design and shape, sometimes for the good sometimes for the worse. A number of drift boat companies got started by a passionate fly fisherman who wanted to make a living building drift boats, but knew little about composite materials in particular and boat design in general. The movie "A River Runs Through It" gave a boost to fly fishing in 1998 and helped those companies to survive for a while.
The way to do it was by making a copy of a copy with little or no modification and no consideration for the esthetic. The result is today a lot of frustrated drift boats owners. For example fifteen years ago, boats were wrongly built with core material into the bottom, today they are falling apart. Potential buyers are very skeptical, because they ave heard the horror stories.
There is no reason however not to expect more than just a floating platform that will get you down the river. In sailing design there is an old saying:
"if the boat is beautiful, she is a fast boat!"
A shiny, waxed and clean drift boat can be the pride of its owner. If a cheap wooden or fiberglass boat will get you to the same fishing spots as well as a more fancy one, in the long run it may worth it to opt for the quality. But quality is time and time is money, some times the size of the budget available leaves no choice.

Design
--------------------------------------------------------------------------------
The main difference between a drift boat and any other boat is that the drift boat goes the wrong way. We don't really need a hull designed for speed as the boat travels at the speed of the water. The only time we need speed is when we want to escape a danger or go back up current. In an urgent situation, a light boat is more important than a sophisticated hull design, but a light boat with a wrong rear end design pushing the water can also be a disadvantage.
Size:
As the principle of Archimedes says, the displacement of the boat will define the draft of the boat--so the measurements and the weight are crucial.
Length:
There are at least two different ways to measure a drift boat: some measure the centerline from bow to transom, which makes sense and is called LOA for length overall. Others measure it along the gunnels which make no sense at all, I would call that an "EGO" complex.
The overall length of a boat doesn't mean much anyway; we should be talking more about length of the water line, LWL. In boat design, the longer the LWL, the faster the boat, we don't really need that for a drift boat as the maneuverability is the most prized quality wanted. In most cases, we could probably cut off a foot or two not needed at both ends of most drift boats, keeping the same floor space but saving weight and limiting windage. Try to picture yourself carrying two five gallons buckets of water attached at the end of a 2x4 on your shoulders as the Chinese people carry loads. If you have an eight-foot long 2x4, you will spin around faster than if you have a sixteen-foot long 2x4.
It does not help the maneuverability to have the front fisherman seventeen feet from the rear fisherman seated way back on the transom. The rear seat placed on a dry storage at the transom is the worse scenario. Most of the time the seat is placed on a swivel but the movement is so limited to a few degrees on each side that the swivel is just here for extra weight.
If the weight is well placed, the boat will spin on a dime. It is also a good thing for the front fisherman to see what's going on under water in the front of the boat instead watching the bow of the Titanic.
Width:
The drift boat goes the wrong way, unlike any other boat. We need a small rear end that acts as front end and that is definitely out of the water in any circumstances. That means at least with three people in the boat and the anchor hanging out, a seat placed at the rear end will put the transom down; pushing the water while rowing back, not good!
We also need a bottom wide enough not to have to counterbalance every time someone leans on the side to grab or release a fish for fear that it is your last trip because you are going to sink and you are not wearing your life jacket. The max width called Beam can be Bmax for maximum width at the hull or BWL for beam at waterline. The BWL needs to be placed at the right place also; The right placement is a combination between the design itself and the options available on the boat. As the boat is relatively small, one person or two in the front can make a big difference. If you have a front bench seat that can fit two people; it is smart to place the BWL where it will balance the weight .
Height:
The distance between the water line and the sheer line is called the freeboard. The professional guides who spend most of their time on the river will have a strong opinion on low freeboard versus regular freeboard and we understand that.
A low side will help a little against the wind but don't think that this is the magical solution when it's windy. If the wind blows, and makes it difficult to get down river, you have then to help by rowing. The the boat is now facing down river . At this point, a low side will reduce the area of the boat offered to the wind by only 10% to 15%. On the other hand the effect of the wind on the gunnels may make it more difficult
It is easier to jump in and out of the boat with low sides especially for an older person or when the boat is in deeper water, but it is also easier to fall over the side in a sudden jerk of the boat. I feel very comfortable spending a night off shore sailing in the ocean, but the river makes me far more cautious. There are many rivers in Montana where I would never take a low side. For a family that makes a trip once in a while on the river, a regular height side boat will be safer for children and more comfortable with very little extra weight.
Weight:
A boat becomes heavy not by choice but because of the way it is built. There is no logical reason to build a heavy boat. A light boat will be easy and fun to row, very responsive, and easy to load on trailer . Heavier boat will take longer to respond, will have a bigger impact when hitting a rock. It will be deeper into the water and it will drift down river faster, but it will help a little on a windy day. Watch for differences in the weight indicated on the description list and the real weight of the boat and watch your back.

主要 区别在漂泊小船和什么条小船之间是漂泊小船去错误方式。我们真 正地不需要船身设计为速度当小船旅行以水的速度。当我们需要之 时速度是我们想逃脱危险或去候补潮流。在一个迫切情况, 一灯塔 船比一个老练船身设计是重要的, 但一灯塔船与一个错误尾端设计 推挤水可能并且是不利。
大小:
因为Archimedes 的原则认为, 小船的位移将定义小船的 草稿-- 如此测量和重量是关键的。
长宽:
有至少二种不同 方式测量漂泊小船: 一些测量中心线从弓到气窗, 有道理和叫LOA 为长宽整体。其他人测量它沿没有道理根本的gunnels, 我称那" 自 我" 复合体。
小船的整体长宽不意味无论如何; 我们应该谈反而关于吃 水线的长宽, LWL 。在小船设计, 比较长LWL, 比较快速小船, 我们 真正地不需要那为漂泊小船因为操纵性是最得奖的质量要。在许多 情况下, 我们能可能切除一只脚或二没需要于多数漂泊小船的两末 端, 保留同样地板面积但挽救重量和限制爆风。设法生动描述运载 二五加仑水水桶附有于一2x4 的结尾在你的肩膀如同中国人运载装 载。如果你有一只八脚长2x4, 你将转动在快速附近地比如果你有一 只十六脚长2x4 。
它不帮助操纵性有前面渔夫十七脚从后方渔夫坐的方式后 面在这扇气窗。这个后方位子安置在干燥存贮于这扇气窗是比较坏 的情节。这个位子被安置在转体的多半时间但运动如此被限制几程 度在各边这个转体是这里为额外重量。
如果重量很好被安置, 小 船将转动在一角钱。这并且是一件好事使这个前面渔夫看见什么正 在继续在水之下在小船的前线反而观看弓Titanic 。
宽度 :
漂 泊小船去错误方式, 什么条小船。我们需要作为前端并且确定地是 出于水在所有情势的一小尾端。那意味至少与三个人在小船并且船 锚停留, 位子安置于尾端将投入这扇气窗下来; 推挤水当荡桨, 不 好!
我们并且需要底下足够宽不必须每次抵消某人倾斜在边劫 掠或发布一条鱼为恐惧这是你的上一次旅行因为你下沉并且你不正 在穿着你的救生衣。这个最大宽度称Beam 可能是Bmax 为最大宽度 于船身或BWL 为射线于waterline 。BWL 需要并且被安置于正确的 地方; 正确的安置是一个组合在这个设计之间本身和选择可得到在 小船。因为小船相对地小, 一个人或二在前线能产生大变化。如果 你有可能适合二个人的一个前面长凳位子; 它是聪明安置BWL 它将 平衡重量的地方。
高度:
距离在吃水线和纯粹线之 间称freeboard 。在这条河上花费大多数他们的时间有关于低 freeboard 的一个坚强观点对规则freeboard 的专家指南并且我们 了解那。
低边将帮助一点反对风但不认为这是这种魔术的解法当它 有风。如果风吹, 和使它难得到在河下, 你有然后帮助由荡桨。小 船现在面对在河下。这时, 低边将减少小船的区域为风提供只10% 到15% 。另一方面风的作用在gunnels 也许使它比较困难
它比较容易跳跃 进出小船与低边特别是为一个比较老的人或当小船是在比较深的水 中, 但它并且比较容易下跌在边在小船的一个突然的jerk 。我感 觉非常舒适的消费每夜在离岸的附近航行在海洋, 但这条河做我比 较谨慎。有我从未采取低边的许多河在蒙大拿。为做一次旅行时常 在这条河的家庭, 一条规则高度边小船是比较安全为孩子和比较舒 适与非常一点额外重量。
重量:
小船变得重不是由选择但由于这个方 式它被修造。没有逻辑原因修造一条重小船。一灯塔船是容易和乐 趣荡桨, 非常敏感, 和容易装载在拖车。比较重的小船长期将需要 反应,有比较大的冲击何时击中岩石。它是比较深入水并且它快速地 将漂移在河下, 但它将帮助一点在一有风天。手表为在重量表明在 描述名单和小船的真正的重量上的区别和观看你的后面。
