Merlin was designed as a compromise between Strider and Gwahir. See the Strider page for deck and interior layout, but basically it has a bunk in each "corner". An optional cuddy cab be fitted, as in photo above

The hulls are finer than on the Strider for improved strong wind performance, but the hulls have more free board and the cabins are longer than on Gwahir, making Merlin a more attractive cruising boat. The interior layout is the same as Strider/Shadow.

We owned a Merlin for 5 years and sailed it in British Columbia, living on board for several months each summer. Shown below is the racing rig

Owner Comments:

"Top speed so far is 20 knots (reaching in a F5 under main and genoa). I am very satisfied with the boat" Wigo, Sweden 

Despite racing three up a Merlin has twice won the "fastest Multihull in Holland" prize

"We have sailed twice with good results. Today we maintained 10 to 12 knots for about 24 miles in 3 foot seas and the boat remained flat and true (and dry!). We get a lot of closely spaced "chop" here, so it was truly a good ride."

Merlin is still easily trailed behind a small car
