Opportunity to buy aluminium dix 38 pilot.

The owners of the aluminium Dix 38 Pilot "Imagine" have enjoyed her for nearly 14 years but have now reached a stage in life when they can no longer do justice to her, to voyage with her as she is intended to do. They have decided to sell "Imagine" to someone who can take her on new adventures.

"Imagine" was built in Italy, with the structure by Aluwind and completion by Alto Adriatico Shipyard in Monfalcone. She was launched in the Adriatic Sea in 2010 and her cruising since then has been confined to the Adriatic and Eastern Mediterranean. She was built and equipped to EC requirements for ocean voyaging and is well-maintained.

She is a true pilothouse in design and build, with dual-station steering, engine controls and electronics, one of them in the cockpit and the other in the pilothouse. Cockpit steering is on a pedestal and the pilothouse has a bulkhead steerer in the navigation station. Also in the pilothouse are chart plotter, radar, VHF and the electrical panel.

On deck "Imagine" has a double-headsail sloop rig, with roller-furling Genoa, hanked staysail, mainsail and spinnaker. She has folding dodger and Bimini to shelter the cockpit.

"Imagine" is currently berthed in Trieste area. Asking price is 280,000 Euro. If interested in buying her, send me an email and I will connect you with the seller. 

This is a well-proven design, with two steel versions having done high latitude cruises to the arctic regions. Go to the Dix 38 Pilot web page for more about the design. I will let her photos tell more about her.

Building the didi 120 "passion xi" - finishing the hull.

David Edmiston, amateur builder of the Didi 120 “Passion XI”, is getting as much of the work done as he can while the hull is upside-down. Each time that I have turned the hull of one of my own big boat build projects it has rained the next day, turning my hull into a paddling pool. That possibility encourages a builder who doesn’t have a workshop large enough to house the new build to do much work that might otherwise have been left for when the boat was upright. I once visited a builder of a Didi 34, with the hull still inverted. He had the interior almost fully complete, including all painting, trims varnished and locker and cabin doors varnished and hung. All of that work had been done by a meticulous builder to a standard that few can achieve.

Photo 36. The hole through the hull has been enlarged to suit the fibreglass stern tube and the P-bracket has been wedged at the height and angle need to align with the shaft. The dowel is fitted through the cutless bearings of the stern tube and P-bracket exactly as the final shaft will be. The P-bracket has wooden wedges securing it at the correct height and angle for least binding of the dowel in the bearing. If the stainless steel shaft is available then it can be used instead of the dowel but the light weight of the dowel makes it much easier to work with. The dowel must be truly straight and round or accuracy will be sacrificed.

Photo 37. The stern tube and P-bracket have now been bonded into the hull with filled epoxy. The stainless steel shaft is now being used to ensure absolute accuracy of the installation. 

Photo 38. This shows the installation of the P-bracket on the inside of the hull. A plywood gusset has been glassed into the hull, making a solid mounting that is braced by the bulkhead. The P-bracket has been trimmed to remove unneeded length and bolted to the gusset. The hole through the hull is cut slightly over-size so that the P-bracket can align itself precisely with the shaft, with the epoxy filler taking up the slight slack.

Photo 39. The engine end of the shaft has been accurately set up on a board that is bolted to the engine bearers to coincide with the intended output shaft alignment, both in height and angle from horizontal. In this design, the stern tube is long enough to pass through and be bonded into a hull frame for long-term rigidity. This area of the hull has been made very rigid by extending the engine beds aft as girders to minimise hull flex in a part of the hull that might otherwise bend under heavy backstay tension.

Photo 41. The hole for the fibreglass rudder port has been cut through the bottom of the hull and the port dry-fitted in place for setting up accurate shaft alignment. The rudder will turn in acetal bushings that are fitted into the port and the fitting through the cockpit sole. Without that upper bearing to ensure accuracy of alignment of the rudder port, so this is done with temporary framing and clamps, seen at the bottom of the photo.

Photo 42. The rudder shaft has been suspended at the correct level to allow checking of all machining.

Photo 43. The rudder port is braced on the inside with plywood gussets fore/aft on centreline and transverse. The fore/aft gussets land on the backbone and the transverse gussets land on plywood doublers that reinforce the bottom plywood. The gussets are glassed over, with the glass extending onto all adjacent structures, making a strong and rigid structure to contain the loads applied by the rudder.

Photo 47. After completion of the epoxy coatings and final fairing, primer coats have been applied, followed by topside paint and the bootstripe.

Photo 48 . Fitting out and painting the interior has continued whenever weather conditions prevent work being done on the outside. Here is owner and amateur builder David Edmiston wielding his paint brush on aft cabin cave lockers.

The next post in this series will cover hull turning and the start of deck construction.

Dh550 "friends forever" finds new friends.

 JJ Provoyeur and Richard Bertie, with a team of artisans, built the DH550 "Friends Forever" on a golf estate in Devon Valley, near Cape Town South Africa. She travelled on a boat transporter along 30 miles of country roads and highways to her launch at Royal Cape Yacht Club , into Cape Town Docks.
