Admiral trailers made me one that can be adjusted for any type of RS Aero trolley or a laser. It was also much cheaper than a Mersea one.

Thank you Issy and Jonathan.
I understood now I have a MK2
The MERSEA I am interested into has a distance aft clip to fwd pin of 270 nad my trolley is around the same. It should work.

Tommy, I have measured both of our trolleys for you. The mark 1 trolley is 230cm from the tang on the front to the front of the axle. The newer trolley (jan 2019) is 258cm. The newer one fits perfectly on the Mersea 250-275 trailer I bought new in September 2019. The older one is too short to reach the retaining pin on the trailer even when adjusted. If you measure your trolley from front of the axle to the tang that attaches to the road trailer that should tell you which one to get. Hope this helps

Hi Tommy,
If you're in the UK or Europe then there isn't one standard trolley; there have been three.
Mk1 - short A-Frame, short gunnel arms, and short handle. Very easy to ground the transom, perfectly balanced for moving the boat around the boat park, good for roof topping, and easier to fit into a Mersea multi-stack trailer.
Mk 2 - longer in: A-Frame, Gunnel Arms, and handle. Much less likely to ground the transom, needs care roof topping on shorter roofed cars, less likely to fit the shorter road base. There is a dimensioned diagram of this trolley in other threads in the same vein on the Forum. I do recall the length from front holding pin centre to front of axle is 250 mm. This is the dimension referred to on road bases when the say it's a 225 - 250 or 250 - 275, to be sure I'd advise you to check.
Mk 3 - I'm not so sure on this version but I believe it is the same dimensions as the Mk 2 but with Gunnel arms that can be adjusted in height between the Mk 1 (low) and Mk 2 (high).
The holding pins on the Mersea trailers, as they are on other makes, are adjustable over a limited range; what is not usually specified is the maximum width of trolley A-Frame.
I carried a Mk 1 home on a Mersea 250 - 275 OK. I've also carried the Mk 2 on one.
Unless you know exactly which Mk # trolley you're going to be trailing then I suspect a Mersea 225 - 250 maybe too short.

Hi, I bought mine in September from RS and it is the 250 - 275 West Mersea one. I have an RS Aero that was made in January 2019 so it has the most recent trolley style. The new trolleys are slightly longer than the one that came with the very early Aeros. My husband has an early one and it’s too short to reach the locking bit on the front on the trailer but mine is perfect. So if you have an older boat with short trolley (the one that has the really low down handle for pulling the boat around) you need the West Mersea 220 - 250 trailer and if it’s a newer one you need the 250 - 275 trailer. Hope this helps. Isabelle

Hi All, Is the 250 WEST MERSEA the correct one to be used with the standard RS Aero trolley?
Thank you
