Wooden ships comments on this Maurice Griffiths

This yacht was one of the most significant prophets of yachting in the post war period. As long time editor of Yachting Monthly and a keen East Coast yachtsman he was one of the greatest influences in bringing yachting to the people. To this end he designed a wide range of small affordable yachts, many of them aimed at the home builder. Building small Maurice Griffiths yachts was work which kept many small Essex and Suffolk yards in business for years.

Being an East Coast man his signature features were shoal draft to creep over those shallow coastal waters and a cabin top extended out to the full beam thus creating volume in the cabin.

The Tidewater is a classic Maurice Griffiths design and well named. She has his classic shoal draft and the cabin roof is extended out to the full beam of the yacht and thus gives a volume in the cabin which one would not believe in a 30’ yacht. The cock-pit is deep, safe and very sheltered because the dog-house roof is extended aft to cover it. With her buoyant bows, 50% ballast ratio, full bilge and good freeboard this is a yacht which will sail relatively upright, she is a dry boat for her size even in a chop and her 4 ½ tons weight gives her a comfortable motion seldom found in modern designs of a similar size.

Timber bilge keels which allowed a full bodied yacht like this to sit upright on a drying berth were optional.

Despite these features her performance belies her looks and like so many MG designs their windward performance is better than one might expect. While she may not be as scary racing round the cans as some modern small yacht designs she will be steady off the wind and with her long keel she will sail herself.

Planked in iroko fastened with copper nails and roves in the traditional way to steam bent oak timbers.

Varnished capping rail and rubbing rail round deck level.

Fore deck raised to the height of the bulwark to give a lot of extra volume in the fore cabin.

Varnished iroko coach-roof raised to a dog-house aft with a roof over-hang aft which gives tremendous protection to the cock-pit and obviates the need for a spray-hood.

A really comfortable and protected deep cock-pit with a bridge deck across the cabin entrance and  tiller steering.

Oak back bone including oak keel, dead-woods, stem and stern post and related knees..

The steam bent oak timbers are doubled over some 8’ throughout the mid-ships sections of the yacht, the additional laminated timbers carried up round the turn of the bilge.

A heavy section bilge stringer runs full length all adding to the exceptional strength of this yacht.

Massive laminated iroko floors with arms carried well up the side of the ship spread the keel and mast loads more than adequately and allow her to take the ground without distortion.

Long external iron ballast keel 2.6 tons with iron keel bolts.

Dec 2011survey indicates no issues with the keel bolts.

Short, stout, varnished plank bowsprit over the stemhead with fixed stainless steel wire bob-stay. The heel secured between twin varnished oak Sampson posts on the fore deck providing an excellent strong point for mooring warps.

A galvanised fitting with nylon rollers half way out the bowsprit allows a self-stowing anchor each side keeping anchors and chain well clear of the ship’s sides and removing the necessity to lean over the pulpit to launch or retrieve the anchors.

Stainless steel pulpit, push-pit and stanchions with gates both sides. Fender Step fenders each side for the not so nimble.


The deck is laid in marine ply, sheathed with grp.

Laminated iroko deck beams, extra heavy in way of the mast.

The cabin coamings and cock-pit coamings are in iroko, finished in varnish.

Deep self-draining cock-pit, well sheltered by the over-hang of the coach-roof deck.

Two seat lockers each side and a bridge deck across the cabin entrance all at the same height, all in varnished iroko.

Self draining well in Cascover-sheathed marine ply with teak gratings. Cascover sheathing is a well established method of protecting the timber using a woven nylon cloth secured with a resorcinol glue. The method has been largely superseded by epoxy and glass cloth which, however, lacks the enormous strength of the nylon cloth.

Tiller steering to a transom-hung rudder.

Double doors over the bridge deck with sliding hatch above to the cabin entrance.

The doors open right back and sensibly all the nav instrument repeater displays are carried on the inside of the port side door, all clearly visible to the helmsman with the port door open. Under the overhang, this presents no danger of flooding except in the hardest weather when the doors would be closed.


Bermudian cutter rig on gold anodised aluminium mast stepped in a galvanised tabernacle on the deck in front of the coach-roof.

Single spreaders.

All stainless steel standing rigging with twin lowers and cap shrouds.

Twin standing back-stays to the quarters.

Inner for stay to the stemhead with Wickham Martin type roller furling gear, the stay set on a quick release McNaughton Clip so that the stay can be removed and the yacht sailed as a sloop on the genoa set masthead to the end of the bowsprit. (this is how the present owner usually sails)

Outer fore stay to the end of the bowsprit with Wickham Martin type roller furling gear.


Boom.             Gold anodised aluminium. Sheeted to a stainless steel horse on the aft deck.                                  Tufnol blocks, lower block fitted with a jammer.


                        3 x Lewmar 6 single speed halyard winches.

2 pairs of sheet winches on the cock-pit coamings, all fitted with rubber top self-                           tailing rings.


Sails                Slab reefing mainsail in excellent condition. Carbon fibre sail battens.Snap                                     shackle on the reef tack and reefing lines run forward to the mast make for                                     smooth and simple reefing.

Nearly new full genoa

Small genoa

Light genoa

No 1 jib

Storm jib


The present owner sails the yacht as a sloop on a headsail set to the end of the bowsprit. He finds she is most easily handled solo with the full main and the jib and then sails very upright but with power and very adequate passage speed.

Spinnaker pole carried vertically up the forward face of the mast.
