船头的固定

[john8848]

上星期卸船时发现，固定船头V－ROLLER的螺母没了，V－ROLLER轴也弯了，吓的出了冷汗。那个WINCH的位置很难固定船头，遇到铁轨，障碍易上下振荡。建议所有的船头另加RACHET直接向下固定在拖车上。

Thanks for sharing your experience, like your bow tie-down transom tie-downs also will help limiting the boat bow from slamming onto the bow roller/axle

好办法，我也照做一个。多谢分享。

Good idea!

我的直觉告诉我，这是好办法。但是感觉，在这个地方应该有一根弹簧。这条带子不仅仅是限位，还要吸收一些能量，减缓冲击。随口一说，未经科学验证。

只要船跟拖架绑得牢為一体，vibration absorbing 的责任都落在拖架wheel axle 的弹簧上、、

楼主用的那款strap的ratchet/toggle lock的鎖力一般，較易鬆掉、、、、

I have two transom tie-downs. I believe that transom tie-down has two functions: 1) Tie boat via boat stern to trailer 2) prevent boat from moving backward.

WINCH的带子必须要把船拉上拖船，船在水里位置底，WINCH的带子要高些，所以WINCH的带子很难把船绑定在拖船上，这个直接把船绑定在拖船的带子绝对有必要，特别是大船，重船。

弹簧 is not good idea. Boat and trailer should be integrated into one to prevent boat from bouncing. Spring is to help to bounce.

for argument's sake....
the bow winch strap stops the boat from falling backwards
the transom tie-down stops the transom from bouncing up and down, moving sideways, and at the same time it also contributes, no matter how small in magnitude, to stopping the boat from moving forward and backwards...
It depends on how the transom, tie-down & trailer framework /bunk (where the tie-downs hook) are configured
