Being a fairly new Norman Boat owner (2 years) I am wanting to understand which type of trailer I need to transport my Norman 20 on the road. I have been looking at bunked trailers and roller trailers but have no idea what sort I need to buy. Any one out there who can advise and you may also know of someone who has an appropriate one for sale.
A bunked trailer is suitable. A twin axle would be best It took me a long time to find mine I needed one to carry my 32. A wanted add works well. I have bought many items with a wanted add. Although I bought my trailer on a buy it now on Ebay. Have a look at it on here listed as my new boat
A roller trailer is much easier to use to launch a boat than a bunked trailer. A roller coaster trailer which has the rollers on swinging beams is even easier still and can be used on a shallower slipway.
For a Norman 20 you need a trailer that can take a minimum load of 1 tone but the weight of your boat could exceed this with all your stuff in it etc. A single axle trailer is easier to manoeuvre by hand than a twin and had one less axle to maintain. A twin axle will allow greater payload and means more security if you pick up a puncture.
Make sure you check the brakes and bearings of any trailer you buy by raising each side and spinning the wheels. Listen for any noises and then apply the brake by hand. Ensure the cables move freely. Take the trailer for a ride around the block and feel each hub for undue heat and any signs of significant rust or brake dust on the inside of the wheels.
A galvanised trailer will last so much longer than a painted one.
I'm happy to give this advice as I learnt it all the hard way and have had to replace all bearings and brakes on a trailer I bought on eBay

Consumedbynature has pretty much covered it. Rollers make launch and recovery so much easier, but drive the price up. A twin axle trailer is not necessary for a N20 - there are many single axle trailers that can handle that payload. Check for adjustability of the rollers/bunks on the trailer, especially if it was previously used for a different boat. On mine, they are all attached with clamps and U bolts, and it gives loads of adjustment, which is useful for getting the nose weight right.
Depending on your budget, don't be surprised if a trailer needs new wheel bearings and/or brake servicing. They are pretty much a consumable on a boat trailer since they are regularly getting dunked - especially if it's in salt water.
You may well need B+E entitlement on your driving licence (if you passed your test before 1997, you should have that already).
