CHB Senator

The published record on this model and what owners report, with the questions worth asking while a boat is still a listing. This page covers the model. Every boat still needs its own homework.

A Taiwan-built single-diesel sundeck trawler with economical hull-speed cruising, but wide unit-to-unit build variation makes condition matter far more than model.

The CHB Senator (commonly a ~35' sundeck trawler, with a larger 43' also built) is one of many near-identical Taiwan trawlers from the Chien Hwa (CHB) yard, whose hulls were farmed out to small family yards for completion. That completion process means build quality varies widely boat to boat, so a thorough survey plus a separate engine survey with oil analysis carries more weight here than model reputation. Senator-specific documentation is thin; most findings below come from the broader CHB/Taiwan-trawler owner community as a reasonable proxy and should be verified on the specific hull. Powerplants vary: single Perkins 6.354, single Perkins 135, or (on the 43) twin Yanmars have all been reported.

Build & Provenance

CONTEXT
CHB hulls were completed by varied family yards, so quality varies widely The basic CHB hulls were farmed out to small, family-run yards in Taiwan for completion. Some yards used sound practices, others cut corners, so two boats of the same model can differ sharply in build quality. For this family of boats, the condition of the specific hull matters more than the model name. src: BoatTEST; Trawler Forum (CHB/Taiwan trawler owner discussion)
CLAIM
Commonly a ~35' sundeck trawler, with a larger 43' also built One quoted Senator 35 spec sheet lists roughly LOA 34'4.5", LWL 31'6", beam 12', draft ~3'3". A Senator 43 sundeck was also built. Dimensions vary by hull and should be confirmed against the actual boat. src: Trawler Forum, 'Senator 35' (JR Yachts spec sheet quoted)

Handling & Range

CONTEXT
Economical hull-speed cruiser at around 7 knots This is a displacement trawler, not a fast boat. Senator 35 owners report cruising near 7 knots at ~1950-2000 rpm with fuel burn right around 1.8 gph; the twin-Yanmar Senator 43 cruises ~7-8 knots at about 3 gph. Comparable single-diesel CHB 34s report roughly 2 gph at hull speed. That economy suits the Loop well. src: Trawler Forum ('Senator 35', 'Senator 43')
CONTEXT
Usable range depends on tank capacity, which varies Fuel burn is favorable, but actual range hinges on installed tank capacity, which varies by hull and can be reduced by age, contamination, or partial condemnation of old tanks. Treat range as a function of the specific boat's confirmed usable capacity, not a fleet number. src: Trawler Forum

Systems

QUESTION
What is the age and condition of the fuel tanks? On Taiwan trawlers of this vintage, original fuel tanks are a common concern and can lose usable capacity or develop leaks with age. No Senator-specific tank data was confirmed, so the specific boat's tank material, age, and condition should be established.
Your move: Ask the owner for tank material, age, and any replacement or repair history, and have the surveyor inspect and (if possible) pressure-test the tanks.

Air Draft & Bridges

CLAIM
Sundeck/flybridge layout tends to raise air draft The Senator's sundeck with flybridge is exactly the configuration that pushes air draft up. No verified Senator air-draft figure is documented. Owners in Senator threads repeatedly asked each other for bridge clearance without firm answers, and the quoted spec sheet omits it. A lowerable mast and hinged radar arch are the common way boats in this class reduce height. src: Trawler Forum ('Senator 35'), Yachtway
Your move: Physically measure the actual air draft with antennas, mast, and arch both up and down, and identify exactly what can be lowered; do not rely on any listing figure.
