Pictures of trailer bought from Andy Seedhouse in Woodbridge Suffolk, take a look at his website a vast array of boats and well worth a visit if you like looking around boatyards, and a stroll along the river is a must as well to see the houseboats. http://www.andyseedhouseboats.co.uk/
This is a diagram from th Alacrity 19 Yahoo site which has been a huge help in learning about these boats and no doubt will be a source of help when I get stuck!
Well I now have a trailer for Sea Witch as above pictures show. It needs some minor modification but seems sound and has new tyres and bearings seem okay. It used to be for a Silhouette but an Alacrity is only around 200kgs more in displacement from what I have read so I hope it will be okay.
