Seidelmann 25 Buyer's Guide
The Seidelmann 25 is a Bob Seidelmann-designed recreational keelboat built by Seidelmann Yachts in Berlin, New Jersey, and now out of production. On the used market it appears in the United States, where buyers will find a 24-foot-6-inch masthead sloop with a fin or optional shoal keel and tiller steering.
Layouts on the Used Market
The interior sleeps four, with a bow double V-berth and two straight settee berths in the main cabin. The galley is to starboard just forward of the companionway, fitted with a two-burner stove and sink. Headroom is below average for the length, so taller buyers should sit below before committing.
Equipment and Common Upgrades
The masthead sloop rig uses 66.8-foot, 5/16-inch halyards for main, genoa, and spinnaker, with 24.5-foot genoa sheets and a 61.3-foot mainsheet, all at 3/8 inch; a viewing should confirm the running rigging matches those lengths and diameters.
What to Inspect
Some owners have complained about poor construction on these boats, so inspect the fiberglass hull and deck for inconsistent laminate, weak joints, and sloppy wood trim where it meets fiberglass anchor. Because the design is tender in heavy air with its narrow waterline and soft bilges, check the keel-to-hull union and ballast integrity for any prior stress cracking or repair that could worsen the inherent heel behavior. When viewing, confirm the head just aft of the bow cabin on the port side and the starboard galley are securely mounted, as loose fixtures signal neglected joinery.
Availability and Buyer's Takeaway
Seidelmann 25s are found in the United States. Before you buy:
- Inspect hull and deck laminate for poor construction signs
- Check keel union and ballast for stress repairs
- Verify halyard and sheet lengths match rig spec
- Test headroom comfort below against your height
- Confirm galley and head mounts are fastened securely
