Talk about SUF, well not so short (pun intended)
There's even a Short Singapore (earlier virant of the flying
pontoon featured).
Short S.5, S.12 and S.19 Singapore

Twin-engined biplane flying boat. The Singapore III was the first
all-metal flying boat of the RAF. It was powered by four engines in
two tandem pairs between the wings. The Singapore I and II had been
unsuccessful prototypes. A few were still in service at the
outbreak of WWII. About 40 built.

Four-engined, biplane, general reconnaissance flying boat with a
crew of 6.
One of the mainstays of the RAF flying-boat squadrons at home and
overseas in the years just before the war, the Singapore III was
the last of a long series of Short biplane flying boats and the
immediate predecessor of the Sunderland. The Singapore III was the
final service version of a design which originated with the
Singapore I (N 179) of 1926. The Singapore I was powered by twin
800-hp Rolls-Royce H 10 engines driving tractor airscrews, and
differed also in having a single fin and rudder and a pronounced
overhang on the top wing. A Singapore I was loaned by the Air
Ministry to Sir Alan Cobham for his memorable 23,000 mile flight
round Africa in 1927-28. In 1930 the Singapore II (N 246) appeared,
this being the first version to mount the twin tandem engine
lay-out so characteristic of the Mk. III.
The Singapore I did not go into production, but in August 1933 the
Air Ministry ordered four development aircraft from Shorts to Spec.
R 3/33 for trials at the Marine Aircraft Experimental Establishment
and with squadrons, these being the first Mk. IIIs. The first Mk.
III (K 3592) flew on 15 June 1934. Production terminated with K
8859 in June 1937 after 37 had been built for the RAF. The five
production batches were K 3592-3595, K 4577-4585, K 6907 - 6922, K
8565-8568 and K 8856-8859.
Singapores first entered service with No. 210 Squadron at Pembroke
Dock in January 1935. First Singapores sent overseas were No. 230
Squadron's, to Alexandria in October 1935 and in Singapore from
January 1937. In September 1937 Singapores on Nos. 209 and 210
Squadrons were sent to Malta to institute the special anti-piracy
patrols as a protection for British shipping during the Spanish
Civil War. Temporarily based in Algeria, they returned to England
again in December 1937. Nineteen Singapore IIIs, by then in full
camouflage war-paint, remained in service at the outbreak of war in
1939. No. 205 Squadron, based at Singapore, retained four
Singapores on its strength until as late as October 1941 when it
handed then over to the RNZAF.
