Looks like the Slipway Trent – not sure of the scale but see they have fittings for 1/16 scale Trent on their website – under lifeboat fittings – but no kit . Unfortunately these would be too large as the Trent was nearly 47' – this 20" hull appears to be 1/28 approx – at 1/16 would only be 33'.

However the pics of the fittings might well give you an idea of what is needed

Model Slipway produced a little kit called the Rescue Boat (so as not to offend or break the copyright of RNLI). It was essentially a mini-Trent and mainly vac-formed styrene, like the Puffer and Drifter kits. This is the kit pictured. It was one of Lawrie White's "Why not?" projects; you might be able to contact Jackie White for possible further details either via their website or through The Other Forum where she posts as Model_Slipway.

When I built mine, the "fittings" were, depending on the item, either vac mouldings on the sheets, or wire that could be cut, shaped and soldered. Things like life rings, deck cleats and bollards, when the need came for replacement, I just got the right generic size from Reade Models, who were exhibiting at a show at the right time.

It was never intended as a comprehensive super-scale model.

I diverged from the instructions a time or two – instead of using the supplied cross-hull shelf for the battery, it lived fore and aft on top of the prop shaft. Better stability, and it became possible to use a 7 cell pack. The shelf was good for mounting the radio, ESC and servo. I eventually used a speed 400 motor and a smaller prop.
