Raf Rescue boat 1502 this was based in Tocyn Brwyn Pwllheli and was looked after by my Grandfather WJ Gould who was also a coxswain On the Pwllheli lifeboat.

As I dont have a plan of the actual boat but do have a plan of a resuce launch by Barrie Griffin the baisic hull is pretty much the same on all the craft so new upperworks will be assembled freelance so to speak.

ST 1502 was built in Hythe by the British Power Boat Co Ltd in 1942. She saw wartime service in various part of the UK and was armed and fitted out for Air Sea Rescue duties. She came out of RAF service in the mid 1950s and went into private hands to be converted to a pleasure craft. ST 1502 continued to give fine service in this capacity but eventually fell into disrepair and was taken on by the British Military Powerboat Trust in the late 1990s to be restored to her former glory. This task was given to a party of ex-RAF sailors from the Air Sea Rescue & Marine Craft Sections Club, (Hants & Dorset Branch). The project began with the complete strip down of ST 1502 to bare bones. From there, the vessel was rebuilt. ST 1502 was originally built of wood, designed on the hard chine principle with single diagonal mahogany side planking and double diagonal bottom planking, also of mahogany, on frames. The superstructure was fabricated from wood and extended aft from the wheelhouse to the cockpit. The superstructure roof was of Flexopy, covered with canvas and supported by mahogany beams. She was powered by twin Perkins S6M diesels, Meadows gearboxes and direct drive to Nickel Aluminium propellers. Later craft of this kind had a fuel capacity of 130 gallons, a range of 150 miles and could attain a maximum speed of 23 knots, with a continuous cruising speed of 20 knots. By November 2008, ST 1502 had been waterborne for three years and was operational in the Southampton area. In 2009, she was transferred to the Portsmouth Historic Dockyard open to view by the public.

The hull is being built form Balsa wood for lightness but the hull stringers and the actual hull sides will be form light ply 


All the bulkheads prior to being glued to the balsa

Glued to the Balsa planks

These were all cut from the planks with a scalpel ready to be glued to the keel

As I needed some stringers bent to go around the hull a jig was built up using some nails as a former,A Kettle was used to steam the wood for it to bend and was left overnight to dry

As I need to do the deck a Boat stand was needed so it was out with the profile Guage to get the profile of the Hull so it could be transferred to wood for the stand

With the stand made attention was then moved to a deck,the hull was placed upside down of a piece of play and scribe'd around to give a deck

Right then filler work,I use this stuff in work or Top Stop or Easy light these are the best fillers on the market in my opinion far far superior than your Milliput,P38 etc,These are superfine and so so easy to sand

Raf Rescue Launch ST 1502 47276690642_04617d6e64_cIMG_3082 by David Jones, on Flickr

Having applied some filler it looks a lot more on a pic than actually was put on

The hull was then coated with laquer to seal the wood then with filler primer ,this will be a good base for painting later on

Right then the part I wasnt looking forward to but it cam together quite  well in my opinion....well I would say that

First of all some measuring of the other hull and superstructure to get some idea on cabin heights and lengths etc and I deicided in the end what was pleasing to the eye was right.Must admit looking at pictures it isnt far off to be honest with you 

Guesswork and reworking on one side and it works

A Bit More back ground information


ST 1502 was the third craft of the third batch of this type to have been built by BPB as their Yard No. 1888. The craft was taken on charge by the RAF on 24.03.42 and immediately despatched to be used by 51 Air Sea Rescue Unit (AS RU) under control of Coastal Command at Penrhos and Pwllheli in Wales. The tender remained based at the unit for virtually all of her WWII service before being transferred to No 56 ASRU based at Portaferry. The allocation was recorded as 30.05.45, however ST 1502 was not received at her new base until July the same year.
Within a few months the craft was on the move to be based at Alness, in Scotland, still with Coastal Command. This allocation was dated 18.10.45 and the craft recorded as received at Alness in November 1945. Post war the ASRU's were deactivated and replaced by Marine Craft Units (MCU). Thus ST 1502 was allocated to 1100 MCU on 23 .08.46 which was based at Invergordon. In line with RAF policy at that time, most surviving wartime built seaplane tenders were "converted" or had a role change and were thus redesignated as Range Safety Launches. Several of the original Mid craft including ST 1502 were upgraded to MkIA specification in the early 1950's. ST 1502 was taken in hand at 238 Maintenance Unit (MU), Calshot on 17.5.50 for conversion on authority dated 14.2.50 (A73418). On completion RSL 1502 was returned to be based at Invergordon/Alness until she became surplus at the end of 1955. The craft was stricken off charge by the RAF on 31.12.55 and subsequently offered for disposal as lying at the RAF base at Calshot.
