The RNLI had lifeboats similar to the USCG's lifeboat, the CG type "E" (blue hull) was based on the RNLI "Liverpoole" lifeboat. The Liverpoole boat was oar propelled as opposed to the American version which was gas engined powered (the sails and oars were auxillary power).
I would imagine a pilot boat or a fishing smack could be built using the Glencoe hull. I've seen some "O" guage rail road layouts using the 36' as a commercial fishing boat. As an example of a different configuration, look at the picture with the gray hulled boat. It represents the "Arctic Cruiser" the Coast Guard used on the icebreaker "Eastwind" in WWII as a survey boat. The freeing ports in the lifeboats hull were deleted and its self righting ability was eliminated. The "saddle" of the deck was more in line with a conventional cabin cruiser of the time. Post war the CG painted the boat white to match the icebreaker. These modified lifeboats served aboard the icebreaker fleet when new 50 foot survey boats were put into service in the 1960's.
