SR4.7 project

Starting my SR4.7 project within the next couple of weeks.

First it's going upside down to have the hull chips filled and polished then going to need to buy a new trailer.

Want to buy the best trailer for a balance of easy launching and great hull support for long journeys.

Thinking of one with rear swing beam and carpeted side supports.

Any views

Rear swing beam and a pair of side support rollers will be fine and easy to recover onto.

SR4.7 is so light and easy to handle, just about any type of trailer will be alright, but the swing beam type give you more of a target to aim at, if driving onto the trailer is your thing.

My Main problem is the lack of decent trailer suppliers round my way.
My local trailer supplier is De graff and wasn't at all impressed with them after my brother in law bought a brand new one. First time we winched the boat on, the swing beam rollers were so loose that they buckled over so much they took a couple of lovely big chunks out of the spray rails.

Going to go for Snipe or Rapide.

I may have a good chance of getting a pristine 75 Yam, what do you think on a 4.7?

CLH trailers in St Clears are excellent and will make a trailer to whatever spec you want.
Yam 75 is a lovely motor, but max power on an SR4.7 is 70hp.

I am not connected with De Graaff trailers but I have purchased about four trailers from them in recent years and can only say good things about them. You get value for money the quality is good and being a small family firm they worry about their reputation and give good after care service.

Due to the close tapering spray rails on the Seariders it is difficult to get a roller trailer were at least two rollers do not bridge a rail at the some point on the hull.
I purchased a standard roller trailer from DeGraaff (Blue rollers in pic.) for my SR4.7 and you can see some of the rollers bridging the rails.
With the boat on the trailer (To enable exact positioning) DeGraaff changed and positioned the rollers. The new rollers (Black ones in the pic.) do not bridge any of the rails and it is so easy to lunch.

Lovely SR4.7 there, A.C.

Not so keen on your trailer though - having the roller bunks welded to the main side rails isn't as effective as a swinging cradle system for launch/recovery in shallow water.

They are not all welded/fixed.

The front ones are in a fixed position but bolted to the main frame so can be moved if required. The rear group of rollers are again all bolted and on on a swing frame making it very easy to lanch into any water level without fowling the trailer.
Due to the size of the trailer having just the rear group of rollers on a swing beam is all that is required with the front ones just acting as support.
