3.Most centerboard boats can be trailered and easily launched and hauled out on boat ramps (larger centerboard boats may require deeper ramps).

大部分活动龙骨船只可以被拖车运载，并很容易通过船舶下水滑道(boatramp)放入水中(当然，大型的活动龙骨船可能需要使用更深的滑道)。

4.Finally, some historic craft have leeboards instead of centerboards; these boards, mounted outside the hull on both sides, can be pivoted down like a centerboard to resist leeward motion.

最后，一些历史上著名的船只使用下风板(leeboard)取代活动龙骨板；这些下风板悬挂在船只底部的两侧，可以像活动龙骨板一样被放下来以抵抗侧向晃动。

5.The centerboard can be raised to decrease displacement to allow the boat into shallower water - and it should swing up and back if it hits the bottom when sailing with it down.

当船只需要进入浅水区域时，活动龙骨板可被提起，以减小船底深度——即使不将其提起，它在船只行驶中触碰到水底时也会来回上下摆荡。

6.Shallow draft centerboard vs. deep fixed keel - trailerable vs. launched by boatyard.

12.When the centerboard is lowered, the boat gains more stability against the wind.

当中心板放下时，船在风中的稳定性增强。

作文

Sailing has always been a passion of mine, and one of the most intriguing aspects of sailing is the design and functionality of different types of boats. Among these designs, the use of a centerboard (中心板) stands out as a remarkable innovation that enhances a boat's performance and maneuverability. A centerboard is a retractable keel that can be lowered into the water to provide lateral resistance, allowing the boat to sail more efficiently against the wind. This feature is particularly beneficial for small sailboats, where stability and control are crucial. When I first started sailing, I had the opportunity to learn about various types of boats, including those equipped with a centerboard (中心板). I was fascinated by how this simple yet effective mechanism could drastically change the sailing experience. Unlike traditional fixed keels, which can limit a boat's ability to navigate in shallow waters, a centerboard can be raised or lowered depending on the conditions. This flexibility allows sailors to explore areas that would otherwise be inaccessible, making it an essential tool for adventurers like myself.The mechanics of a centerboard (中心板) are relatively straightforward. It is typically housed in a slot in the hull and can be lowered using a line or lever system. When lowered, the centerboard creates significant drag, which counteracts the sideways force exerted by the wind on the sails. This means that the boat can maintain a straight course even when the wind is coming from the side, a situation known as 'beating.' The ability to beat effectively is what separates experienced sailors from novices, and having a centerboard can make this maneuver much easier.Moreover, the centerboard (中心板) also plays a crucial role in enhancing the overall balance of the boat. When sailing, weight distribution is vital, and the centerboard helps to lower the center of gravity, contributing to a more stable ride. This stability is particularly important during rough weather conditions, where a well-balanced boat can make all the difference between a smooth journey and a tumultuous one.In addition to its functional benefits, the centerboard (中心板) also embodies the spirit of innovation in sailing. Many modern sailboats incorporate advanced materials and technology to improve the efficiency of centerboards. For instance, some manufacturers use lightweight composites to create centerboards that are both strong and easy to handle. This evolution reflects the ongoing quest for improvement in sailing design, where every ounce of weight saved can lead to better performance on the water.As I continue my sailing journey, I have come to appreciate the significance of the centerboard (中心板) in enhancing my skills and experiences. Whether I'm racing against friends or simply enjoying a leisurely sail, the presence of a centerboard allows me to explore new horizons with confidence. It serves as a reminder of the beauty of sailing—a blend of nature, technology, and human ingenuity. Ultimately, the centerboard is not just a piece of equipment; it represents the freedom and adventure that comes with sailing, encouraging us to embrace the open waters and all the possibilities they hold.

航行一直是我热衷的事情，而航行中最引人入胜的方面之一就是不同类型船只的设计和功能。在这些设计中，使用中心板（centerboard）作为一种出色的创新，提升了船只的性能和操控性。中心板是一种可伸缩的龙骨，可以降入水中以提供侧向阻力，使船只能够更有效地迎风航行。这一特性对于小型帆船尤为重要，因为稳定性和控制力至关重要。当我第一次开始航行时，我有机会了解各种类型的船只，包括那些配备中心板（centerboard）的船只。我对这种简单而有效的机制如何极大地改变航行体验感到着迷。与传统的固定龙骨相比，中心板可以根据条件升降，这种灵活性使得水手能够探索那些原本无法进入的区域，使其成为像我这样的冒险者的重要工具。中心板（centerboard）的机械原理相对简单。它通常安置在船体的一个槽内，可以通过绳索或杠杆系统降下。当降下时，中心板会产生显著的阻力，抵消风对帆施加的侧向力量。这意味着即使风从侧面吹来，船只也能保持直线航行，这种情况被称为“迎风航行”。有效迎风航行的能力是区分经验丰富的水手和新手的关键，而拥有中心板则可以让这一操作变得更加容易。此外，中心板（centerboard）在提升船只整体平衡方面也发挥着重要作用。在航行过程中，重量分布至关重要，而中心板有助于降低重心，从而增加航行的稳定性。这种稳定性在恶劣天气条件下尤为重要，良好平衡的船只可以在顺利航行和动荡之间产生巨大的差异。除了其功能性优势外，中心板（centerboard）还体现了航行中的创新精神。许多现代帆船采用先进的材料和技术来提高中心板的效率。例如，一些制造商使用轻质复合材料制作既坚固又易于处理的中心板。这种演变反映了航行设计中持续追求改进的过程，在水上每减少一盎司的重量都可能导致更好的性能。随着我继续我的航行旅程，我越来越欣赏中心板（centerboard）在提升我的技能和体验中的重要性。无论是与朋友比赛还是享受悠闲的航行，中心板的存在让我能够自信地探索新的地平线。它提醒我航行之美——自然、技术和人类智慧的结合。最终，中心板不仅仅是一件设备；它代表了航行带来的自由和冒险，鼓励我们拥抱开阔的水域及其所蕴含的所有可能性。
