Leisure 17 and 17SL

Designed by Arthur Howard and produced by Cobramold for the 1967 London Earls Court Boat Show,  the Leisure 17 is one of the most successful small yachts ever built.

The Leisure 17 stands up well to her canvas, is light on the helm and a very easy boat to handle. Ideal for short-handed and family crews.

The L17 was produced by Cobramold under Brian Meerloo until 1980 and then by Brinecraft  under Tom Winyard until 1987.   Further L17s were reportedly built in Europe.

SL Version

In 1975 the "SL" version of the L17 arrived. Brian Meerloo designed  and  produced a more modern looking "wedge shape" coach roof  which provided more headroom in the cabin.  See below, "Typical SL Specification".

Unfortunately the company records of Cobramold  and Brinecraft were lost in the catastrophic fire in 1987, but it is estimated that  at least 3,400 Leisure 17 and 17SL's were produced in a 25 year period from 1967 to 1992. 

Read L17  Solo Crossing of the Atlantic

The reputation of the L17 as a tough little cruiser was assured in 1968, after German sailor John Adam,  successfully crossed the Atlantic, single handed,  from Weymouth to Antigua via the Canaries in Eve, one of the first Leisure 17s

Solid Construction

The hull is built in solid GRP and apart from the very earliest models, the cabin top  and sides having GRP linings. This construction provides great strength and maximum insulation.

Cast iron fin or twin keel configurations are available, with the twin keel version having a high aspect ratio hydrofoil section.

Rudder and skeg are glassfibre with stainless steel framework and fittings. 

Engine Power 4/5hp Outboard

Auxiliary power is normally provided by a 4 or 5 hp long shaft outboard on a transom mounted bracket. 

The spars are made of aluminium alloy, originally gold, the spars of later boats are black or silver. Halyards are internal. Standing rigging and rigging screws are in stainless steel.

The large self-draining cockpit has a transom locker for a gas bottle and storage for the outboard when not in use.

However, these days,  larger four-stroke, long-shaft outboards will not fit easily in this locker.

The deck has moulded non-slip areas for safe working.

Accommodation

Down below, a four berth arrangement is standard, two in the fore peak and one either side in the main cabin that run down the whole length of the cabin. 


A camping type gas hob and grill is normally fitted under the companionway. 

Alternatively, a three berth arrangement is possible, with a large cockpit sail locker replacing one of the quarter berths.

Performance 

The Leisure 17 is quite often raced, with significant success in small cruiser classes.

 However, the only racing handicap information we have are Portsmouth Yardstick (PY), Secondary Yardstick (SY), various Recorded Numbers (RN) and Club Numbers (CN) as shown below.

For cruising boats, The RYA has updated the Portsmouth Yardstick scheme with the National Handicap for Cruisers (NHC). 

More up to date information may be obtainable from the RYA NHC site and the Byron  web site.
