Worth a look if

Latex mattress traced to your berth

Good

Trace your own berth with the free kit; hinges, splits, bevels and any shape are included, in 6″, 8″ or 10″.
2 firmness choices: Luxury Comfort (most popular), Luxury Plush (extra soft; 8″ and 10″ only)

A trawler owner said Portland already had his boat's pattern on file, the fit was perfect and the mattress very comfortable.

Think about

There's no trial or return: the guarantee covers fit only, and the mattress is cut a bit smaller than the berth for sheets.
A Catalina 34 owner's three-piece latex V-berth mattress (2014) arrived too small. He was told only afterward that it is cut 1/2″ smaller all around for bedding, which left gaps in the V. It was re-cut free, but only the next season.
Owners call it expensive: one said 'not cheap', and the Catalina owner said he paid over $2,000 CAD.

Questions

What is it made of?

Made-to-measure latex boat mattress. A quilted top of plush foam and fibers in a 'CloudTouch' fabric sits over a premium latex comfort layer and a 'MarinePure' latex base, with a waterproof vinyl bottom ('AquaGuard') to keep moisture out of the core. The Plush version swaps in a softer latex comfort layer. Made in Maine.
