Wooden Ships Comments on this Harrison Butler Z4 Tonner
Harrison butler Z4 tonner, designed by T. Harrison butler and built by Alfred Lockhart (Marine) Ltd of Brentford in 1938.
Refitted by the current owners in 2023 with a thorough refit, full list of works below.
The Z4 is one of the well known designs of T. Harrison Butler, an amateur yacht designer and Opthalmic surgeon by profession, who produced some very fine, well mannered and capable yachts. The name is derived from the Thames Tonnage of the design, a measure of useable interior volume.
The boat has a comfortable cabin with 2 good sized single berths and ample sitting headroom. The compact galley with a Taylors stove is crisp and practical. The Forepeak has a heads compartment with sitting headroom under the forehatch.
A very smart and well presented example of the class with a detailed recent refit history and seemingly very much ready to go.
Length on deck 22’
Beam 7’
Draft 4’
Thames Tonnage 4TM
2023 Refit List
- The hull was carefully taken back to bare wood to remove many paint layers and after repairs the hull was primed with three coats of Epifanes Underwater Primer and two coats of Seajet Antifouling.
- All the strap bolts were replaced and all the related plank areas were repaired.
- Straps were cleaned in situ and cold galvanized and then protected with two coats of Zingatarfree. A system we’ve used elsewhere that seems to work well.
- The iron keel was mechanically abraded to bare metal and coated with three coats of red lead paint, then antifouled.
- Where the hull opened while drying, or where repairs had been carried out, the seams were cleaned and the areas re-caulked. About 1/3rd of the hull was re-caulked.
- New engine beds were made and fitted. The keel bolt under the engine bed was replaced. This was made and galvanized for us by David Webster at Deep Blue Engineering.
- The metal engine bed frame was removed, shot blasted, cold galvanized and given three coats of Zingatarfree.
- While working on the hull we came across the previous sockets for beaching legs. We repaired these and have restored them. Legs need to be made.
- On the deck the tabernacle was removed and re-galvanised and the four holding boats were renewed.
- The stem protection strip that runs from deck to keel had rusted and this was removed and replaced with stainless 316 and re-fastened.
- The stemhead fitting was cold galvanized and rebedded.
- We inherited stanchions, pulpit and pushpit with the boat which some previous owner had made and which had subsequently been removed. We galvanized these and they have been refitted with dyneema lifelines.
- David Webster at Deep Blue re-built the boomkin which was found to be weakened by rust, and at the same time he fitted an attachment method for a Pacific Light self-steering. The Pacific Light is not part of the sale but it in first tests is seen to work well.
- David Webster at Deep Blue remade and galvanized the upper and middle rudder pintles and these were refitted to strengthened transom mounts.
- The lower chain attachments for the boomkin were repaired and all the fastenings and chain replaced.
- The fuel tank was removed and cleaned and fitted with an extra shut-off valve and proper breather pipe.
- The fuel tank was changed from hanging by a few screws to sitting on a new beam and then rigidly fixed.
- The filler cap to fuel tank had previously been leaking and this arrangement was changed and improved.
- The central Ringframe was found to be weakened at the base by rust. The rusted area was cut out and repaired with a 316 stainless strut – also made by David Webster at Deep Blue.
- A reconditioned engine was fitted after complete service to all systems.
- The interior of the boat has been repainted from bilge to deck ceiling.
- The relatively new Collars mast was stripped of fittings, which were regalvanised, and the mast given 11 coats of varnish.
- An improved VHF aerial was fitted to the mast with better wiring and stronger mount.
- The boom was given the same treatment as the mast with fittings removed, galvanized and with 11 coats of varnish to the wood.
