Decided the Visby class would make an ideal project so started to accumulate the necessary bits.
Another modeller donated a pair of used KMB 28mm waterjets, but missing the reverse / steering nozzles. After this stroke of luck, turned to obtaining the missing nozzles. Thought getting a pair would be easy!

Made innumerable attempts to make contact through the KMB website. Then E mails and even telephone calls from Canada to place an order, got absolutely no response.
Finally, in desperation, thought as “RN in Munich” lived in the same country and speaks German, perhaps he would be able to make contact locally. Doug gave his usual generous support.
After many attempts - nothing (thanks again Doug – now I know what Fleet Admirals are for!). Fortunately, we both gave up.

By now had obtained some scale GA drawings and printed them off at the appropriate size. Discovered that the KMB jets were too big to fit in the stern recess anyway!
Searched for alternatives and found there are many different sizes available.
Through AliExpress, found a 22mm jet unit made by MSQ. With some trepidation, ordered a pair.
These arrived quite quickly and were nicely manufactured. Think they are 3D printed, but not sure. Anyway, they look good and robust. With minor modifications, they will be fine. The KMB are the black and the MSQ white in the photo.
With the wisdom of hindsight, it might be easier to install an even smaller unit, but too late. Anyway, the 22 mm should move more water than a smaller one.
As the original vessel could do some 35 knots, this should make max. speed more realistic.
The challenges of squeezing these units into the available space do not look insurmountable. Rather too late anyway as now have them.

Been trying to find an interesting model for my next build and was intrigued by the articles on a semi-scale waterjet powered Finnish stealth corvette in the Model Boats magazine. Thought that a similar model would be an interesting introduction to the world of waterjets.

Quickly discovered that to make a scale model with a manufactured glass fibre hull (my preferred construction), would have to find a similar vessel as nobody offered a GF hull for that ship. The author of the article had made his semi-scale model by adapting another hull.

After searching around, discovered then decided on the Swedish Visby class. This was an early version of a stealth corvette and has had excellent reviews in the various defence forums. Was waterjet powered and of similar dimensions, meeting my requirements.

Concluded this would make a nice project, so started to accumulate the necessary parts.
Researched the class in more detail and found Swedish naval vessels are also know as “H.M.S.”, but in Swedish! The Swedes have a proud naval tradition and use a similar nomenclature to the British. They are referred to as “H.Sw.M.S. XXX” amongst the Naval fraternity.
