What Wentworth by the Sea Marina does
Wentworth by the Sea Marina, doing business as Safe Harbor Wentworth by the Sea, is a premium full-service marina located at 116 Morgans Way in New Castle, New Hampshire, within Little Harbor and minutes from historic downtown Portsmouth. The facility accommodates recreational vessels from 36' to 200' LOA (max beam 35', max draft 12') across wet slips, transient slips up to 220', and seasonal wet winter storage. On-site amenities include a 24/7 self-service fuel dock selling ValvTect marine diesel and gasoline, a ship's store (ice, apparel, bait), vessel detailing, courtesy vehicles, and an on-property waterside restaurant (Great Island Eatery). Charter experiences are offered through three on-premise partners: Seacoast Boat Charters, Ledge Runner Charters, and Shoals Fly Fishing. The property holds a verified 5.0-star rating across 137 reviews on the Safe Harbor website.
The marina is wholly owned and operated by Safe Harbor Marinas, LLC, a private limited liability company that controls a network of 100+ premium marina locations across the United States. Technology is limited to a parent-managed marina management and booking platform, with third-party transient reservations processed via the Dockwa marketplace. Revenue is generated through subscription-style annual and seasonal slip rentals, pay-as-you-go transient dockage, winter storage contracts, per-gallon fuel sales, retail and charter referral commissions, a restaurant lease, and on-site vessel detailing. Pricing is quote-based and not publicly disclosed. GTM is primarily direct field and inside sales for wet slip and storage contracts, with self-serve transient booking via Dockwa for short-stay customers. The Safe Harbor membership program extends the property's addressable market to traveling boaters who purchase network-wide access. The marina employs 23 people and operates as a single-asset property within Safe Harbor's broader national portfolio; no standalone financial statements are publicly available.
