SeaPiper 35 – Launched for the first time

We launched SeaPiper #1 !

She is floating right on her lines, is cute as heck and offers wonderful stability due to her hull shape and relatively high ballast factor. We did some initial trial runs up and down the river to get a feel for how the boat performs.

SeaPiper #1 is not completely finished yet: there is some interior finishing to do, transom doors need to be added, bow roller installed, and the side boarding doors need a bit more work, but this won’t take long. We were anxious to get her in the water to get some preliminary test data.


We were most pleasantly surprised by her characteristics: the boat tracks really well, and even though she has a narrow beam she is not tender or “tippy” at all. Once power is applied she picks up speed smoothly and quickly and steering is crisp and responsive. We are going to refrain from listing sea trial speed and rpm data at this time because we need to correct the propeller pitch some more: we have the boat under-propped a bit right now. So stand by for final data, but performance and handling are looking really good ūüôā

Use Examples for SeaPiper 34

Cruise the Caribbean:

Go cruise the Caribbean. SeaPiper has fantastic range, offers comfortable motion, ample speed plus great space on deck as well as in the salon and galley. She will have a wonderful sun shade over the complete cockpit and superior ventilation throughout the interior, both in the forecabin as well as in the main salon. Her shallow draft allows true gunkholing in shallow waters. Her comfortable salon and cockpit allow for great entertaining options.


The Great Loop:

SeaPiper is perfect for doing the Great Loop. Her long range, great cockpit seating and comfortable pilothouse/salon combination are a real asset. She has a cockpit aft as well as the large center cockpit and therefore docking and mooring will be a snap, even single handed: walk out of the pilothouse and drop a line over the side.


Long Scuba Trips:

A great use of SeaPiper is for weeklong scuba trips. Her wonderful access to the water with those boarding ladders make this boat ideal. There is lots of space in the cockpit, and there is lots of space in the storage room under deck for scuba equipment: air tanks can be stored vertically, fins, wet suits, masks etc. You can stay on the boat all week if you equip her with a dive compressor.


Fishing off the Atlantic Coast:

Go fishing off the Atlantic Coast. SeaPiper offers plenty of cockpit area to make this very enjoyable with up to about 4 people. Remove one or both deck boxes to create more cockpit space and make this kind of use even more convenient. She has great range and will allow use very far out if need be.


Lobster and Crab fishing:

Use SeaPiper for small scale lobster or crab fishing: her side entry doors and open cockpit with the deck boxes removed allow for plenty of crab or lobster pots on deck and space to operate and it will be a lot of fun. Ideally mount a very short mast with lifting boom on the factory installed mast support and you can hoist pots with ease. With a bit of creativity the catch could be put in bins in the storage room under the cockpit.


Pacific Northwest:
Cruise the San Juan Islands in the Pacific Northwest. SeaPiper is easy to maneuver, has wonderful directional stability, and is perfectly suited for this environment. Keep the sunshade/rain shade up to make use of the cockpit in any kind of weather. Her practical floorplan with large galley offers comfortable living and the separate forecabin gives a sense of privacy.


Travel to Bermuda:

Travel to Bermuda, which is easily within reach of SeaPiper. Her strong scantlings and four independent watertight compartments will offer great peace of mind on a longer passage like this one.

Deck Sockets and Locking Feet SeaPiper 34

Deck Boxes / Cockpit Seating and Boarding Ladder

SeaPiper 34 offers comfortable Cockpit Seating on Deck Boxes with comfortable seat cushions. These deck boxes offer great storage space on deck and are mounted to the cockpit sole using shallow deck sockets and separate feet made in 316 stainless steel. The feet have external tabs that lock behind corresponding tabs in the deck sockets if they are turned 90 degrees. They are stopped from rotating further by a pin which is pushed through both the foot as well as the sleeve it rotates in.

This locking mechanism is a simple and structurally strong solution that allows the Deck Boxes / Cockpit Seating units to be removed at will and also leave the boat owner feeling secure about the deck box mounts.

The boat comes with a Boarding Ladder that mounts into deck sockets right inside the Side Boarding Door opening and because it uses the same locking mechanism as the deck boxes it offers easy deployment and removal. The boarding ladder can also be installed on the Swim Step aft, again using the same deck sockets and locking pins. Updates with more detail images are soon to follow on the Main Gallery and the Center Cockpit pages.

We will continue to update the News Blog pages with SeaPiper 34 feature highlights and construction updates. People interested in the SeaPiper 34 Trawler please browse our extensive internet website on

Refining design details

Over the past few weeks we have kept ourselves quite busy with refining various design features of the SeaPiper 34. Mundane but very important details such as door and hatch seals were finalized and added to the Bill of Materials. The goal has always been for our boat to be the very best in its class and therefore I feel that spending lots of time refining these details is time well spent.

Then we updated the website with various new images and also added an equipment list and pricing for the boat.

We developed this website to showcase the boat and as a tool to build a list of interested people and we are now seeing inquiries from all over the world. If you have any interest in this design please do not hesitate to contact us. We will gladly answer any question you may have and give you updates on the tooling and production timeline as it stands now.

And most importantly: we know that many of you will have ideas for features to incorporate. Please share these requests with us at this time so we can see about incorporating these into the design.

Welcome to the SeaPiper blog!

SeaPiper 34 was born out of a desire to create something special: a compact seaworthy boat with very long range, with great safety features for boat and crew, and which offers a comfortable motion for the crew on board.

We have been working diligently on getting her design finalized and at this time we are in the last stretch of the design phase before committing to tooling. Starting from a napkin to the current design has been a long haul: Countless evenings were spent doing 3D modeling, going over calculations, doing research on the optimal hull shape for its intended use, creating it in CAD, and thinking through effective technical solutions to sometimes complex problems.

All through the design work we talked to many boat owners about how they use their vessels and what they would like to see in their next boat. We kept refining the design, talked to more people, until everything came together as you see it here: our new SeaPiper 34.

We will keep you updated on SeaPiper 34 news using this blog, and we hope you will enjoy reading about what is truly a remarkable vessel!
