I’ve just purchased an armor 700/MG classic. I’ll need to trailer it out of the marina it’s currently living in.
Does anyone have hull dimensions or trailer dimensions from their own trailer/boat so I can confirm things like bunk height, wheel clearance etc?
I have a tyrone snell breakback trailer, it has a spine of rollers and some adjustable height bunks, I ideally need to know how much higher the bunks need to be than the rollers, I am under the impression these are very flat bottomed, the bunks are 1.4m apart, I could move them out a little more if need be, or inward. I was under the impression that 0.7m from the centerline is approximately 20cm up, but I am struggling to find any concrete info on this.
Welcome to the club. I do nut fully understand what you are trying to say.
Most important is that the trailer can handle the weight of the boat. Rollers are adjustable on most trailers, and with the keel up your boat should fit on a shallow trailer (you’ll just have the hull form to fit)
Post the specs, and maybe a foto of your trailer, and we might be able to help you further.

I’ve got the same problem. I recently bought a Vlemmix 1800 trailer, but I don’t know how high the side rollers should be set. What’s the difference in height between the rollers in the middle of the trailer and those on the sides?
Can I lift the boat out of the water on the trailer whilst the rollers are in their lowest/ a low position (what height?) and then raise them further once the boat is on the trailer, or is the boat too heavy for that and do I have to have the boat hoisted the first time and adjust the side rollers to the correct height whilst the boat is still suspended from the crane?
How does that work in practice? I am a novice in trailer country
this is the trailer in it’s current state. The images are a little deceptive, those d rubbers are about 30cm above the central rollers, at 1.4m separation, I can shift them out further if need be, and lower them a lot more, but I am under the impression the boat is very flat, so I may need to worry about the mudguards contacting too. (I can move the upper frame up to lower the wheels and mudguard if need be too)
I intend to add an inner set of bunks to act as a guide for the rollers too. Like a V.
It all feels like guesswork until we’re soaking wet in the water. Poking at a boat and trailer!
If yours has centre rollers, I believe most of the boats weight can sit on the central rollers and the side ones are largely to stop it rocking from side to side. I think if you can’t get it hoisted, very slowly trailering it out, getting extremely wet and adjusting the roller heights to suit is probably the way to go. My worry is my rollers are too low so I my boat will be sat on my mudguards, it looks like your trailer won’t have that issue at all.
I think you can change the side bars for rollers too, if they are adjusteable, hoist the boat out with a crane, lower it and adjust the rollers to fit. After that is done you should be able to trailer the boat in and out of the water.
What is the maximum weight on the axle? Most trailers have double axles to be able to carry the boat
Ah, was not clear to me this is the same boat as a New Classic 700. This weekend, I can measure the postion and heights of the rollers on my NC700 trailer. I can make a simpel drawing if that helps.
I did take measurements of my NC700 trailer and made some overview drawing. Probably way too complicated but I hope it helps you.
The measurements are in mm which suggest an accuracy that is not there. I did try to measure everything with 5mm accuracy with a roller tape and some reference beams.
photos trailer
First of all some photos of the trailer for reference.
As the side and bow roller are on a frame which can pivot (see photos) I can not directly measure the roller positions. Therefore I defined the reference of the rollers where they pivot. I will first tell where there reference points are and then give an overview of the reference points of the rollers for the whole trailer.
The center rollers are easy. I took the midle of the rotation axis as reference point:
Now the reference points are defined, here’s the overview of where the ref points on the trailer. For the height reference I took the plane defined by the trailer beams as the zero plane.
Note that the center roller right before the axle lies 60mm below the zero plane. The keel is actually resting on this roller and it’s about 5cm below the hull. The side rollers here are actually also slightly (15mm) below the zero plane.
Top op mud gards are 190mm above the zero plane and are there is 170cm room between them.
Rated max load
My trailer is rated for 1700kg which I think is on the low side. Technically the trailer should be able to carry a higher load. The axle itself is rated for 2000kg.
I hope this helps (although I made it probably way too complicated).
there are swing keel sportina’s but the hull with the keel lifted is the same, only the keel, and the inside of the cabin differ. (the harbour where my boat lies, has a sportina with a swing keel)
