Refits (Annual)

SCORPIO undergoes comprehensive annual refits far beyond the scope of most pleasure yachts. For the last 12 years SCORPIO has worked as a very successful term charter yacht plying the waters of the Lesser Antilles (the Windward & Leeward Islands) of the Caribbean. In order to keep her updated, looking her best & in a well maintained condition to minimize the risk of breakdowns during the charter season, SCORPIO is hauled annually in Trinidad (south of the Caribbean hurricane belt) for the sole purpose of refitting. As well as the "normal" annual maintenance tasks - re-antifouling, replacing anodes, engine/mechanical gear servicing, re-varnishing, etc., we try to take on a more major project each year - to give some idea of this here is a brief description of recent years refit projects:


  •  Aug -Nov 2019 - Numerous smaller maintenance tasks relating to the upkeep of the boat were undertaken this year- these include extensive re-varnishing, upgrade & replacement of safety gear in preparation for Atlantic crossing. All stanchion bases (original & corroded) were replaced with new & stronger aluminium ones.
  • July-Nov 2018 - Prepare and respray the entire hull topsides and deck areas - applying Snow White Awlgrip 2000 paint and KiwiGrip non-slip deck paint. Additionally, all cabin sole floorboards were removed, stripped and re-varnished using 2 part polyurethane varnish.

The binnacle mounted Raymarine sailing instruments were all either replaced or manufacturer refurnished - replacing the lcd displays which had deteriorated over time through UV degradation.

All interior headlinigs were replaced and new ceiling mounted led lighting fitted throughout the accommodation.

  • July-Nov 2017 - De-rig the boat, lift mast and strip all parts from mast & boom. Sand-blast mast & boom to remove all paint & prepare aluminium surface for etching & repainting. Inspect mast and repair any suspect stress cracking before repainting. Re-step mast, replacing old partner wedge chocks with Spartite Mast Seal System. Replace Forestay, Inner Forestay & Cap Shrouds. Overhaul Genoa & Staysail Profurl Roller Reefing Systems. The island seat in the saloon was made by a local cabinet maker & was designed to contain an additional fridge/freezer unit - it was also fitted on stainless steel slides to allow it to sit partially under the table when in the stowed position but be slide out to allow comfortable seating when desired.

All deck hatches & the saloon coachroof windows had new plexiglass fitted replacing old UV degradation.

  • July-Nov 2016 - The aft double cabin en-suite heads compartment was originally fitted with a bath tub! With a shower & curtain above it this proved to be singularly impractical for those forced to use it. The bath tub was therefore removed & the entire compartment re-modelled to include fitting a separate shower stall. One notable feature of SCORPIO is that, in order to minimise the number of through-hull fittings & seacocks, both heads handwash basins & the bath tub (now replaced by a shower unit) are drained through a simple internal plumbing system into the wet bilge sump and hence pumped overboard by the automatic bilge pump.

A bespoke drinks cabinet and bookshelves was constructed & fitted to the saloon.

The original Volvo Penta 120SE saildrive unit (which had been overhaul the previous year was still proving difficult to select reverse gear) was replaced & upgraded will a new Volvo Penta 130S unit.

All through-hull fittings & seacocks were checked - several were replaced.

  • July-Nov 2015 - All underwater hull areas were stripped of the build-up of many years of antifouling. The hull surface was then prepared and 3 coats of epoxy coating applied before re-painting with ablative antifoul.

The engine was given a full top-end overhaul including replacing & re-seating the valves, replacing the coolant pump & replacing the cam belt. The injector pump was replaced , as was the starter motor. The gearbox on the 120SE saildrive (which had been proving difficult to selecting reverse gear) was also completely overhauled.

The deck decking on the aft decks & in the main and helmsman's cockpit was entirely replaced.
