The basic specifications are set out in the table below. There are variations between all Seacracker-Trintella's, so the data below is from Sergeant Pepper - you might then want to look at her inventory; amazing what you can fit into a small boat!

Engine
The engine is a three cylinder 20 HP Volvo 2020 marine diesel installed in the Summer of 2000. This is mounted below the bridge deck/cockpit sole.  The engine drives a three bladed fixed propeller via conventional flexible shafting and a Hurth reduction gearbox.  Full engine control (single lever) is provided from the steering position.

The fuel tank is mild steel and has a capacity of approximately 25 gallons.  This is placed aft of the engine, just below the cockpit sole, and uses gravity feed via copper fuel lines.

The engine has a dedicated starting battery which is and also has a 60 Amp-hour alternator.  The house supply is provided by two independent 12 V batteries which are charged via the engine alternator.  Isolating switches are fitted as is a Volvo split charge relay. 

Rigging
The mast is deck stepped with a keel mounted support below decks.  The mast, boom and spinnaker pole are of anodized aluminum and the standing rigging is made of 7 mm stainless steel wire.

The jib is roller furling and the mainsail fitted for slab reefing. The standard sails include a half battened main, 156% roller reefing genoa, 100% (working) jib, storm trysail, and spinnaker.

Sergeant Pepper has a removable inner forestay which is taken from just below the masthead to a point on the stemhead fitting. Fitted in 2001, this enables her to carry a proper working jib or storm jib in heavy weather, with the roller reefed genoa firmly secured. The forestay is tension with a SeaSure Hyfield lever as used by the Royal Navy for securing large life raft canisters.

Deck
Twin bow rollers lead off a dedicated stowage compartment for the anchors.  A stainless steel Sampson post also serves as a hawse pipe.  Fitted throughout with lifelines and leading aft to a stainless steel pushpit, the deck is made safer still through the provision of deep scuppers and stainless steel jack lines. 

On Sergeant Pepper, the ground tackle is as follows:

Main anchor:
25 # CQR + 175' x 5/16 chain.

Storm Anchor:
35 # Fisherman +  60' x 3/8" chain + 150' x 3/4" braid.

Spare Anchor / Kedge:
20 # Danforth + 60' x 3/8" chain + 150' x 3/4" braid.

All lines are lead aft fairly to two single speed winches and the sheets to two dual speed self tailing Harken 44ST winches.  The lines are not interfered with when the heavy duty spray hood is fitted.  The deck has a moulded -in non-skid surface and has several teak grab rails for safety.  The cockpit has one of the two Henderson manual bilge pumps ready for use, the other being located within a locker in the cabin.

Steering is via a laminated wood tiller, supplemented by a Raymarine Autohelm 4000+ control for use under power.
