keel height on a trailer

Is the any reason I shouldn't try and get the keel as low as possible on the trailer?


I've previously been told that the boat should be high enough off the ground that, if the engine should swing back down it won't hit the ground.

I'm tempted to get it as low as poss as it'll lower the centre of gravity and also make launch/recovery easier ( I has to use 20 m of rope and a lot of pushing at Warsash on saturday)

Low is good - but you MAY discover that the front of the keel will strike some of the axles/crossmembers when recovering. If so, some carpet or extra rollers will help.

Trailers are a curse!

I prefer mine as low as practically possible as long as your careful and don't forget to trim up before you leave you'll be fine
Although I did have a pal who had a waterski slide over and activate the trim switch mid journey which ground the skeg down pretty good

I've got heavy rubber fendering from the back an HGV trailer fixed to the top of the axle with BIG cable ties. Keel sometimes touches it but with engine trimmed out I can drive the boat right up to the snubber, lean over the bow and clip on to the trailer. Makes launch & recovery so much easier.

Yes low down and as far apart as you can get them to give the boat best support

be VERY careful changing anything on your trailer.

i damaged my brand new keel first time recovering due to a poorly setup trailer.

if you change anything then get carpet everywhere to stop taking chunks out the gel.

Unfortunately i can't reach my bow eye by leaning over so if you can do this that in itself would be of use.

Be careful of your fender (or worse, bare tire) rubbing on the tube bottom. That's usually the determining factor in how low you can sit the hull (at least in my experience.) Aside from that and the skeg problem (I use a motor support; takes that one out of the equation), lower is generally better unless you have really uneven roads to travel.

When making changes, remember that launching and recovering puts the trailer in a nose-up attitude compared to the hull. Your first contact point will be deeper than how the hull sits on the trailer out of the water.

I noticed when I was into hard boats that the wider trailers that your laws allow meant that the boat chines could sit lower between the wheels whereas ours needed the boat to be set above the wheels. We have been given and extra 3 inches recently but "EU type approval" still has us using 1940's style rod operated drum brakes.

I fitted and extra bow eye set where I could reach it.
Almost crippled myself climbing over the front of PM's Ribeye onto the trailer on Saturday to get at the bow eye that's set so far back under the bow of the boat.......nightmare.

Is it worth extending your winchpost vertically then so you can attach a short line to it, to hold the boat in place, and then connect the winch to the eye from the outside?
